So I bought one, it's very nice. But it sounds a bit different than I remember my original sounding, and my other clone as well. So I opened it up, expecting to see a 4558 opamp, instead of the correct TL072. Well, the opamp is correct, but surprise, surprise, CSW has reduced the circuit. There should be two (2) TL072 opamps, but there's only one (1). What the hey? Can someone with the understanding of how this junk works explain to me what they might have done, and why? I expect it's to get the pedal to fit in that little box. But what has it done to the sound?
