    I posted it above, but when I realized a Fuzz Face was a schmitt trigger things made a lot of sense.

    Put it first in line, get a nice amp tone going where the pedal pushes it into distortion. Try the impedance all the way up and all the way down and roll your volume back in both cases to see how it interacts.

    Usually if it’s a high input impedance it’ll be fine anywhere in the chain, the lower impedance will cause more interesting things to occur which could be beneficial or not based on what you want.

    Can't beat a common sense approach to these things. I never thought about it either, but I'm also not a fuzz or vintage pedal guy.

    Don't forget impedance. Just as important. I'll make a new thread.

    Surprisingly, the Fuzz Face circuit is affected not just by a buffer in front,but also by one after it.
    Turns out that downstream loading can actually be used to tune its sound.
    I only recently realized this.

    One solution would be to mod the fuzz with a cap to ground.
    With true bypass, it can be done in a way that won't affect your tone when the pedal isn't engaged.

    They don’t. The input impedance of the TU-2, TU-3 and TU-3W are different. Reportedly the TU-2 was 1M, the TU-3 is 2.2M and the TU-3W is 1M or True Bypass. If you compare the TU-3 to the others you might find it slightly brighter if it’s the first in line.

    ehdwuld, I think your DS-1 plan sounds good. if you find weird things happening when you engage/disengage a pedal, you can consider an output buffer. Technically it’s “better” to have one, but “technically” a Fuzz Face is a Schmitt Trigger that doesn’t belong anywhere near an audio path!


    The reason for the output buffer is to make the impedance relationship between the pedals and the amp input common. In rare cases you could step on a delay or chorus pedal and all of a sudden you are driving the amp input differently causing a tonal or gain change. I had this happen with the Belle Epoch, when turned it on the tone changed (which in some senses it’s supposed to, but I had it set as transparent as possible) but I didn’t like a volume bump when the delay went on. Switching it to buffered/preamp always on was great. That was it was a little extra goose into the amp’s input all the time.

    What kind of tune is it? If it's a Boss TU it has a buffer.

    Easier than that. A buffer needs power to work. If you unplug the pedal and still get sound, it doesn't have a buffer.

    Usually I only keep buffers on my distortions because that's what the guitar sees first. After that I don't particularly care so long as it's not a crappy buffer, but you don't see those too much these days.

    Depends on the fuzz you have. Fuzz faces and primitive type fuzzes (tone benders, etc.) usually like to be first. A big muff doesn't care.

    The DS-1 is buffered. I'd put the tuner after the fuzz and DS-1 - just kick off the gain to tune and kick it back on when you're done. This way you've only got one pedal before the buffer.
