Wiring Diagrams

We have a lot of wiring diagrams available to help you make your instrument sound great. We work hard to make installation as simple as we can, but you need to have some technical and mechanical ability to do it well. Soldering isn’t difficult, but it takes some skill and tools. We highly recommend finding a professional guitar tech to do installations.
