Luthier for Fender Guitars and Basses
We inspect Fender guitars and basses in a workshop approach: diagnosis, setup, frets, headstocks, tremolos, and passive electronics.
Taller
Cómo trabajamos Fender
If you're looking for a luthier who truly understands Fender guitars and basses, the first step is to separate myth from real symptoms. Many Stratocaster arrive with tremolo instability when the problem is a combination of nut, springs, and setup; many Telecaster arrive with fret buzz that is actually due to improper action and nut balance; many P and J basses arrive with noisy electronics due to neglected output jack or ground.
At Raven Custom Guitars, we work with these families every day in setup, maintenance, frets, nuts, bridges, and electronics. We are not an official Fender service: we are a workshop in southern Madrid that applies a diagnosis protocol before recommending a refret, pickup change, or any major repair.
We also do not promise timelines or parts without seeing the instrument. What you can expect is a clear technical reading: what is fine, what should be corrected, and in what order it makes sense to do it.
This page summarizes how we approach the brand, which models we document in our catalog, and what you can expect when requesting a in-person inspection with your Stratocaster, Telecaster, or Fender bass.
Construcción y uso
Información técnica
- Origen
- Estados Unidos
- Notas técnicas
- Las Fender más habituales en el taller combinan mástiles atornillados, escalas cortas o largas según modelo y radios y geometrías que varían según modelo, serie y época. En Stratocaster y Telecaster vemos diapasones de arce barnizado o palorrosa sin barniz, con implicaciones distintas al nivelar o retrastear. Los puentes sincronizados de seis tornillos permiten configuración apoyada o flotante; los de dos pivotes en algunas series requieren otro criterio de reparto de muelles. En Jazzmaster y Jaguar entran vibratos de superficie y electrónica con circuitos propios; no comparten el mismo mapa de ruidos ni de ajuste que una Stratocaster. En bajos, Precision y Jazz difieren en anchura de cuerdas, separación de pastillas y respuesta del puente, lo que condiciona acción e intonación. Los trastes suelen ser de níquel en instrumentos estándar; cuando se solicita acero inoxidable valoramos dureza, instalación y touch resultante. Las cejuelas originales pueden ser de material sintético o hueso según serie; un cambio mejora la afinación solo si el slotting es correcto. Tolerancias de fábrica, intervenciones previas y condiciones ambientales explican por qué dos instrumentos idénticos sobre el papel no se comportan igual. Por eso medimos antes de ajustar el alma, contrastamos humedad relativa cuando hay movimientos estacionales y documentamos modificaciones antes de proponer piezas aftermarket. En Fender pueden encontrarse radios y configuraciones diferentes según modelo, serie y época; deben verificarse antes de realizar trabajos sobre trastes o diapasón.
- Materiales
- Arce, palorrosa, pau ferro, aliso y fresno en cuerpos y mástiles; trastes de níquel o acero inoxidable bajo solicitud; cejuelas de hueso o materiales sintéticos; componentes electrónicos pasivos y hardware compatible con cada familia.
- Acabados
- Poliuretano y poliéster en series actuales; nitrocelulosa en determinadas líneas vintage o Custom Shop; acabados satinados o brillantes; instrumentos relic o aged con necesidades de mantenimiento distintas. No asumimos un único acabado para toda la marca.
- Compatibilidades
- Raven trabaja guitarras eléctricas Fender, bajos eléctricos Fender y, cuando procede, algunas guitarras acústicas de la marca. Atendemos instrumentos de distintas series, épocas y mercados, con hardware original o piezas aftermarket siempre que su compatibilidad quede verificada por modelo, año y medidas reales.
- Mantenimiento
- Evite cambios bruscos de humedad y limpie el mástil con productos adecuados al acabado. Revise periódicamente tornillería de muelles y clavijas, lubricación del trémolo y estado de cuerdas. Tras un cambio de calibre, planifique un reajuste. No gire el alma sin medir el relief; un desgaste avanzado de trastes se notará antes en cejuela y acción que forzando el mástil.

Workshop experience with Fender instruments
At Raven Custom Guitars, we review Fender guitars and basses in our workshop with a careful approach: first understanding the instrument, then proposing the work. Each unit arrives with a distinct history — caliper changes, previous interventions, fret wear, electronic modifications, or simply years of honest use — and that conditions any setup or repair.
Our regular work includes diagnosis, truss rod and action setup, nut and bridge inspection, calibration of Stratocaster tremolos, leveling or refret when necessary, nut replacement, passive electronics upgrades, and preventive maintenance. We do not substitute physical inspection with assumptions: what works in a neck may not work in another even if they share the same brand and family.
How do we approach each inspection
We measure the relief, check the neck straightness, evaluate the condition of the frets and nut, listen to the electronics, and compare symptoms with the actual use of the instrument. Only then do we decide whether a setup is sufficient, whether leveling the frets is appropriate, or whether a refret makes technical and economic sense. This order avoids unnecessary repairs and returns an instrument consistent with its construction and context.
Fender Guitars we work with
Most of our experience is focused on the families that come the most to the workshop: Stratocaster and Telecaster, in American, Mexican, and other origins. We also work on Jazzmaster, Jaguar, Mustang, and derivative models when the owner needs a setup, maintenance, or repair.
Stratocaster and Telecaster
They are common references in the workshop. On Stratocaster, we usually check floating or fixed tremolo systems, pickup height, balance between springs and nut friction. On Telecaster, the focus is usually on the nut, three-string fixed bridge, action, and simple but sensitive electronics.
Jazzmaster, Jaguar and other families
These models have particularities — surface vibrato, custom electronics, scales and distinct ergonomics — that require specific diagnosis. We do not treat them as a Stratocaster with another shape: we adapt the inspection protocol to their hardware and real response.
Fender Basses we work with
We work on Precision Bass and Jazz Bass from different series, as well as Mustang Bass, Jaguar Bass, and variants like Aerodyne when they come to the workshop. On basses, the balance between truss rod, nut, frets, and bridge marks playability just as much as on a guitar.
Precision Bass and Jazz Bass
In Precision Bass, we check string definition, height on the last fret, bridge symmetry, and noise in passive electronics. In Jazz Bass, we add attention to the balance between the two pickups, separation, and possible interference when the instrument has been modified.
Other bass lines
Shorter models or those with specific setups require checking tension, intonation, and component compatibility without assuming they share the same setup as a standard P Bass.
Setup and maintenance of a Fender
A full setup on a Fender is not just turning the truss rod screw. We check the relief with the instrument tuned and in playing position, check the action at high and low frets, measure the nut height and intonation at the bridge, and evaluate whether the tremolo—if present—maintains balance with the installed caliper.
Caliper, tuning and electronics
Changing the caliper involves checking the nut, truss rod, and often the tremolo. Humidity variations in the Madrid area can move a maple neck over time; regular seasonal maintenance avoids guesswork. In passive electronics, we check the ground, potentiometers condition, selector, and output jack before suggesting replacements.
Frets, leveling and refret
Not all fret buzz requires a refret. Many times a truss rod and nut setup, or a spot leveling if there are raised or localized fret wear, is sufficient. Confusing symptoms can lead to costly and unnecessary interventions.
When to set and when to refret
Leveling corrects inconsistencies between frets without changing their overall height. Refretting replaces worn frets and can alter the feel of the fretboard. On maple fretboards with a finish, the procedure is more delicate and should be considered by hand. We also take into account the radius, fret material, and the guitarist's touch expectations.
Bridge and tremolo Fender
On Stratocaster, the synchronized bridge may rest on the body or float depending on stability priorities and vibrato usage. In both cases, the spring distribution, string action on the nut, and proper string installation affect the tuning.
Stability without shortcuts
Before blocking a tremolo, it is advisable to check for a worn nut, loose tuning machines, or an imbalance between the springs. On Telecaster and basses, the work usually focuses on intonation, string height, and the condition of the strings at the bridge.
Electronics and pickups
Most Fender guitars and basses that come into the workshop use passive electronics. We check ground continuity, shielding, switch condition, and induced noise. In single-coil, a certain level of interference is normal; the goal is to distinguish what is expected from a real failure.
Thoughtful Modifications
If changing pickups, potentiometers, or adding preamps is considered, we value reversibility and compatibility with the existing wiring. A well-planned upgrade respects the instrument's character; a hasty one may cause noise or inappropriate potentiometer values.
Common problems in Fender guitars and basses
Common inquiries include fret buzz on the first frets, action misalignment after a string gauge change, fret wear in high-use areas, jack or selector noises, tremolo instability, and too low or worn frets. We do not present them as factory defects: they often combine use, environment, and previous maintenance.
When a technical issue is documented in our editorial catalog, we link it from the brand's public listing. If it has not yet been published, we handle it in diagnosis without promising links that may not exist.
Related services
Fender instrument owners often require a full setup, basic or advanced maintenance, fret leveling, refret, nut work, electronic inspection, tremolo calibration, or pickup change. In the workshop, we select services from the catalog based on what the inspection reveals, not according to a generic list applied to all models.
Maintenance, pre-recording inspection, or structural interventions are only performed when the instrument requires them. You can consult the Raven services catalog to view the scope and general conditions.
Frequently Asked Questions about Fender
We collect common questions about tremolos, necks, headstocks, scales, and bass maintenance P and J. The answers are written to guide, not to conclude a remote diagnosis: year, series and modifications change the final recommendation.
On the public page, the selected questions for this brand are displayed; the internal catalog may include other reusable entries for different contexts.
Request review or diagnosis
If you have a Fender guitar or bass that isn't responding properly, isn't staying in tune, or has fret buzz and electrical noise, the most useful step is to have it inspected in person. Explain which calibrations you use, if the instrument has been modified, and what symptoms appear in its usage context.
You may request an inspection or diagnosis through the contact channels of Raven Custom Guitars. From the inspection, you will receive a clear proposal of work, without generic budgets or promises that depend on seeing the instrument in person.
If you are still unsure whether you need a simple setup or a more extensive intervention, describe calibres, modifications, and symptoms when requesting an appointment. That information shortens the initial diagnosis and avoids assumptions about the instrument, which can only be fully understood at the workbench.

FAQ
Frequently asked questions
The serial number must be crossed with country, format, components and official tables. Some plates, neck and bodies could be assembled at different dates.
No. There are bridges of six screws, two pivots and different spacings. It is necessary to measure posts, screws, block and separation of strings.
No. Jaguar, Mustang, Duo-Sonic and some bass or special models use other scales.
No. Fender has used nitrocellulose, polyester and polyurethane according to time, factory and series.
There is no universal calendar. It depends on usage, humidity changes, caliper changes, and whether the instrument has traveled or remained unreviewed for a long time. Many owners in the Madrid area notice seasonal movements in maple necks. If new fret buzz, action variation, or tuning instability appears, it is advisable to have the instrument checked even if a fixed period has not passed. Preventive maintenance makes sense when the instrument is used daily or before recording and performances.
Tuning instability is not usually dependent solely on the bridge. It can also be influenced by friction in the nut slots, string installation, the condition of the springs, the support points of the tremolo, the tuning machines, or an incompatible setup with the gauge used. Before blocking or replacing components, it is advisable to check the entire string path and correctly balance the bridge, tension, and tuning. In the workshop, we review the entire instrument before recommending an intervention: year, series, and previous modifications can change the applicable response for your Fender.
It depends on how much you use the tremolo and what level of stability you expect. A bridge with support usually facilitates tuning if you hardly use the tremolo; a floating bridge allows for up and down adjustment with more margin, but it requires balanced springs and a properly adjusted nut. There is no single answer for all Stratocaster models: the caliper, bridge height, and musical style influence the decision. It is sensible to configure it after inspecting the instrument. In the workshop, we inspect the instrument completely before recommending any intervention: year, series, and previous modifications can change the applicable response for your Fender.
Almost always, it is at least necessary to check relief, action, nut, and, if it has a tremolo, spring balance. A string gauge change modifies total tension and can move the neck over time. Sometimes a minor adjustment is sufficient; other times it may be necessary to modify the nut or springs. Changing the strings and assuming that "it will sound the same" often leads to fret buzz or unstable tuning in the first few weeks. In the workshop, we review the instrument completely before recommending an intervention: year, series, and previous modifications can change the applicable response for your Fender.
When there are frets that are higher or lower than their neighbors, resulting in fret buzz in specific positions, dead notes, or buzzing that cannot be fixed simply by adjusting the nut. A level does not replace a refret if the wear is deep, but it can eliminate minor irregularities. It is necessary to measure with a fret ruler or fret measuring tool and compare with the current relief before deciding. In the workshop, we review the entire instrument before recommending an intervention: year, series, and previous modifications can change the applicable solution for your Fender.
When fret wear prevents a comfortable setup even though the nut and truss rod are correct, or when there are marked depressions in areas of use. If fret buzz is corrected with a setup, a light leveling is sufficient. Refretting involves cost, time, and possible work on the fretboard finish if it is maple with a finish. We consider remaining height, expectations of touch, and the instrument's value before recommending it. In the workshop, we review the instrument completely before recommending an intervention: year, series, and previous modifications may change the applicable response for your Fender.
Yes, but it requires a more careful intervention than a fretboard without a finish. During the extraction and installation of the frets, it may be necessary to protect, repair, or partially redo the clear coat near the fret slots. The procedure will depend on the wear, the type of finish, and the desired aesthetic result. It should be budgeted after physically inspecting the neck. In the workshop, we review the entire instrument before recommending an intervention: year, series, and previous modifications can change the applicable solution for your Fender.
Correct shielding, solid ground connection, and good quality potentiometers reduce part of the unwanted noise. Shielded pickups or noise-cancelling systems change the instrument's character; you have to decide whether you are looking for silence or the original tone. Before replacing pickups, it is advisable to rule out a loose jack, defective cable, or incomplete ground. In the workshop, we review the instrument in its entirety before recommending any intervention: year, series, and previous modifications may change the applicable response for your Fender. Request a in-person review if the symptom persists after a basic setup.
