Mozztronics - EX-1 Expandrive

There are many variants on two common designs. The tube screamer uses diode clipping around an op amp feedback loop. The distortion + has diode clipping to ground after the main gain stage. Often the distortion stage is followed by a low pass filter to smooth off the sharp clipping caused by the diodes. While these designs sound good, there are some features you can’t “dial in” with these types of pedals. Some people use different diodes with different forward voltage to get a different sound.So this is the Mozztronics take on this style of pedal. We use the diode clipping to ground arrangement, but we have added adjustable asymmetry, and an expansion control which will control how much the character of the distortion changes as you push the guitar harder.
