Op Amp = Sonic difference?

According to several sources I've seen/read/heard, the Op Amp is only a tiny part of the overall sound of a distortion pedal, to the extent that worrying over which one is in there is pointless. The presenter of CS Guitars on YT makes this claim, as I believe, does Josh Scott who fronts the JHS channel, also on YT. Both of them have stated it's the rest of the components - along with the Op Amp - that makes the character of the pedal, and simply changing the OA itself wouldn't make a real sonic change.

I don't know enough about circuitry to argue either way, and without definitive evidence, I say the claim in the article is debatable.

Rat similar to DS-1?

Is the circuit topology really all that similar to a DS-1? A Rat has an opamp that is biased hot enough to distort easily going into hard clipping, going into a simple low pass filter. A DS-1 has a booster transistor stage that is biased slightly hot for a tad of transistor distortion, an opamp stage that doesn't distort at all, hard clipping (same diodes as Rat2), and a big muff style tone control that scoops bass at the right side, treble at the left side, and mids in the middle.

They both follow the formula of boost->clip->tone, but maybe there's a better way to word it to avoid possible confusion that they are based around the same circuit design. 57.140.108.17 (talk) 11:57, 20 June 2024 (UTC)[reply]
