Inspired by a Dumble "a box later", this is my take on the circuit. It's an active loop for pedals/amps, a signal attenuator, a unity buffer, and a +24db clean boost. For use with a 1590BB, 1590BBS, and 1590BB2 sized enclosures. DIY includes the footswitch board, the signal board, and the faceplate.
