Dual Amp Driver

The Dual Amp Driver is my version of the A-B box. Its purpose is to drive two amps with one instrument without loosing signal strength. You can choose either amp "on" individually, or both amps "on" together. This pedal can sound crystal clear or supply a gentle signal boost that can be regulated by an internal trimmer. A little extra gain can be very convenient when you want to add body to your tone or drive more efficiently subsequent pedals or effect processors. One of the problems with almost every A-B box on the market is this: when in "both amps on" mode, there´s no way to know which amp will sound when you go back to "single amp" mode. To solve this, I designed a clever 4 LED´s circuit that indicates which amp will be selected when you go from two amps to one amp only.
