About AMI Guitar Upgrades
Who Is AMI?
We design Made in U.S.A. upgrades for electric guitar and bass. They give you more unique pure analog pickup tones than your "stock" instrument can produce.
Our family of Pickup Switch UpgradeTM products are designed to give you all the additional hidden pickup tones that you cannot get from your stock electric guitar or bass.
Our products are "Lego-like" easy-to-connect-and-use upgrades for your electric guitar and bass. Now you can finally have all the possible pickup tones from your instruments to give you the ultimate in pickup tone power.
​
We use the term "Pickup Coil" (instead of "pickup") that our upgrade products control. This is because some 4-wire humbucker pickups that have two separate controllable pickup coils. There are also "triple-bucker pickup" (one with three separate pickup coils). To avoid confusion, we describe the total number of pickup coils that each of our upgrade products control.
Here are the "core" pickup switch products used in our electric guitar and bass upgrade products. In addition to being bundled with our other upgrade products, these core pickup switch products are also available separately, either as Assembled and Tested version or Kit version.
