  • True Bypass VS Buffer

    ok so I like the long instrument cables

    Josh at JHS, says I need a buffer on either end of my Pedalboard to make up for my cables and ton of pedals
    so I got a tuner and a Fuzz first
    then I can stick the Boss DS-1 in after the Fuzz and just not turn it on
    this gives me my first Buffer

    I have some Behringer reverbs and such I can stick at the end of the line before it hits the front of the amp

    Since Behringers are copies of Boss
    do they have the same buffer?
    Seems like the would

    What about any other pedal not labeled "True Bypass"
    would they have buffers by default or is it just a crap shoot
    I have a Biyang Tri Reverb that does not say True Bypass on its switch
    does anyone know if it is

    is there a test with a meter that can tell if it has a buffer or not?

    On a true bypass the signal will go through even if the pedal is unpowered, because it should act as a piece of cable when not engaged. Unpowered buffered pedals will not let your signal through. At least according to my limited knowledge and experience....

      The half-assed bypass switching arrangement will also pass signal in bypass mode with no power. These pedals always have the input of the pedal circuit connected to the incoming signal, so that even with the effect powered up but in bypass, the input impedance will still be connected in parallel with the input of the next pedal in line.

        thanks for the link that clears a lot up
        and it explains why that old script orange phaser swirls no matter what

          In my experience you usually want to put a buffer as close to the cable that comes out of your guitar as possible. After the buffer you can run a lot of cable and pedals without really caring too much about tone loss. Also important to note - most pedals will act as a buffer when on . . . so when in doubt you can always just stick a clean boost at the front and leave it on all the time to accomplish this.

            Well Josh said not before a fuzz

            So tuner
            then Fuzz
            Then some boost or the Boss DS1

            Like in the Op

            So any pedal at the end of chain will work?

              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.

                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.

                every time I had to play while people sat there drunk,

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

                    I don't know if all Boss pedals have the same buffer, but I changed from a TU-3 to a TC Polytune 3 because the buffer clipped/compressed with hot pickups. I could literally see it when I recorded DI's from the both the main and parallel outs. That's unacceptable, IMO.

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

                        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.

                        Oh no.....


                        Oh Yeah!

                          Well, I guess that means it doesnt have a bypass buffer. It could still have an input buffer or an output buffer in the part of the circuit that is in-line only when the pedal is on.

                            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.
