Interesting. As usual, seeing the real thing explains a lot.80hinhiding said:Anyway, here are my circuits. I just drew them up. I think I should probably add a resistor off the + input on the op amp too.
You could, but you don't have to. 3 Hz as the lower cutoff is good enough for rock'n'roll (and most other types of music I would imagine).80hinhiding said:Oh, 3.3uF for the inputs on the op amp. I remembered seeing those values on another schematic a while back and decided to try them for this one. I'll increase those.
Maybe you should make something (loosely) based on the tube screamer pedal? With a low gain there's not much distortion and the clean sound is always mixed in.80hinhiding said:I've found input impedance and the bias definitely impacted that for me. So I think this might tell me I like some clipping or maybe I like the compliment of a clean tone mixed with a slightly clipped/distorted/compressed one.
Depends on what gear you have in mind. For power amplifiers, what they call bias is more about how much idle current that flows with no signal being input. This is done to avoid crossover distortion, but here it's a single transistor in class A, so it's more about getting it to the point where it operates without clipping.I guess maybe this is why I've seen bias controls on some gear.
Figure out what you actually like? Then analyze the signal to bits That's what I do anyway - it might not work for you. Run test signals through it and look at the results - model it in spice, etc.I'm kind of confused as to what I should do.
