Like do they do that in commercial pedals as if they use some specific batch of opamps that they know how to bias them excatly? Also I´m not sure if everyone who builds clones can hear those little imperfections in their builds.
vvv wrote:I´m yet to familiarize with the biasing-thing, instead, I built a few more pedals and I still haven´t got a single lo/medium gain overdrive to sound right. From 20+ built pedals only fuzzes and some higain overdrives and distortions have sounded like they should. I think many builders just don´t care about their builds sounding wrong or they can´t hear it. I´d really like to hear a sound clip of some Vero-built lo-gain overdrive pedal where somebody plays an open chord gain set quite low and lets it ring and fade out.
It would be good to know what circuits are more sensitive to those problems and just skip building those because I have already spent quite a lot of time with builds I never got to work right...
Maybe I should do some build I have already build once this time using higher quality components and even try to do one with same brand components to a pre-made PCB to see if that makes a difference.
Do you always do biasing in every build to get things right? Is it like a basic prosedure in building?

vvv wrote:Yes, most of the builds I call "broken" can sound just fine like with only single note played, maybe just lacks some sustain, but some specific chord might give really ugly fading. That´s what makes me think most builders think their builds work just fine
vvv wrote:There must be something they are doing differently in commercial pedals as I have yet to hear a broken sounding commercial pedal. They kind of sound "fine tuned" and I have also A/B tested some of clones I build with orginal ones and difference is really clear

It probably doesn't matter in a mix. I think it's more of an op-amp thing, try a transistor based design like a Les Luis.

It was a bit woolly, and yes maybe a wee bit gated at the very tail of a complex chord, it might depend on the particular opamp used (metal can mojo notwithstanding).
