I ordered one and use it with my TC-50. I really like it a lot. I keep it at pretty much the standard 0 gain/max level setting with the gate set at about noon. I did notice I need to dial back the tone quite a bit (and even dial the treble back a little on the amp), as it seems to really accentuate the highs. Great pedal IMO. Curious to see if I feel the need for it with the Invective.
