Your sound should reflect your unique artistry.

Custom Amplifiers

At Golden Phi Amplification Engineering, we provide our customers with the highest quality service and personalized products. Your sound should reflect your unique artistry. Since we build our own line of custom tube amps, we are highly skilled and able to build something that is uniquely yours. Whether you play the guitar, ukulele, harmonica, bass, or harp, we can create an amp specific to your instrument needs. We are sound experts. If you can dream it, we can build it.

Repairs and Modifications

Sometimes an amp just needs a little love. We are adept at any repairs and modifications you might need. Sometimes a simple tune-up or tube replacement is in order, other times major repairs are called for. Whatever you need, contact us for a free and fair appraisal and time estimate. Prices vary depending on the scope of the project, but we love a challenge!
