Wait, what is the blend knob for?
Just got mine. Blend is just what it says... you can blend the raw input signal with the VT output. With the blend all the way on, it is all VT.
Nice pedal... good quality, lots of Ampeg-like clean and overdriven tones, and 'high output settings' for both the 1/4" and XLR to drive most power amps nicely if you want to use it as your primary preamp. The 'brite control' does that super Ampeg bright crunch tone if you want it.
