Routing Guitar Bodies For Pickup Installations
Electric guitar pickups are available in a variety of different shapes and architectures. Changes to a pickup’s magnets and winding specs can have a profound impact on its tone. However, being that the structure determines the size/style of magnet and the number of coil windings that can be fit on a pickup bobbin, the profile of the pickup itself is a major tone defining factor that cannot be overlooked.
Sometimes an instrument’s body is not built to accept the client’s preferred pickup configuration. In these situations, routing may be necessary before the body will be ready to accept the new components.
Deepening A Pickup Cavity For Noiseless Pickups
This instrument came to us after the client had already performed a pickup replacement. Unfortunately, when installed, the new pickup is not capable of being set low enough to avoid interfering with the strings as they are fretted in the upper register. We have to fix this issue before a proper setup can be performed.
After removing the pickup, we measure that the cavity is approximately 23/32″ deep. This was plenty deep enough for the instrument’s original single coil style pickup.
The Fender pickup model pictured is a “noiseless” model. Technically a type of humbucking pickup, it is made from two coils stacked on top of one another. As such, it is nearly twice as tall as a traditional single coil telecaster neck pickup.
Unfortunately, the body is simply not cut deep enough to properly accept this type of pickup.
Using a router, we carefully remove wood from the bottom of the pickup cavity only. The added depth will allow the guitar body to accept the client’s preferred pickup type.
After routing, the pickup cavity is now 7/8″ deep. We believe that this will now accommodate full adjustment of the pickup to meet any desired spec.
With the pickup reinstalled, we are now able to set the height exactly where we wanted to keep the instrument sounding good everywhere on the fretboard and there is a range of adjustment available should it ever be needed.
Widening A Pickup Cavity For Humbucking Pickups
Oftentimes pickup types are categorized by the instrument model from which they originated. For example, a “Stratocaster pickup” brings to mind a pickup much like those shown in the top left corner of the photo (1).
In search of the perfect feel and tone, many players like to mix and match elements from different styles of instruments. Accommodating these requests sometimes requires adapting the instrument to fit new components of different specs.
The top right corner of the photo (2) shows that this instruments body had been cut to accommodate single coil “Stratocaster style” pickups. At the bottom left (3) we see that wood has been removed from the body in order to house the larger size of the humbucking pickup the client requested installed in the bridge position (4). Routing away the wood from the control cavity allowed the clients desired replacement pickups and pickguard to fit onto the instrument.
