It also has a hybrid circuit of tubes and solid-state op-amp to drive the tank, and recover the signal from the tank. This one is pretty simple. One op amp gives 40dB makeup gain for the reverb tank's output, one buffers the dry signal, one is an inverting mixer to blend the dry & wet signals, and the last is an inverting output stage with variable gain (inverting the output is a sin, I think, so I felt the need to invert back to correct). Design a template pedalboard online with Pedal Playground. It can be used to improve an instrument sound or used to make a poor singer sound better. We provide you with the latest news, reviews, and info about the gear you love from brand leaders in quality & innovation.
