    Hi friends,
    I own the 70’s version (brown with the yellow text and tone switch).
    Do you find this pedal usefull? It does have sustain to die for, but the fact that it has no tone knob makes the sound very thick or very thin, no inbetween. Additionally, it seems like there are almost no difference when moving from the neck to the bridge pickup.
    What is your opinion? How / with what other pedals do you use it?

    Try it in front of a wah or a phaser :love: Muffs always sound great with filters, IMO.

    Or you can mod it — that board is a 1322 board from a regular full size big muff but with resistors across the pads for the sustain and tone pots. Throw a trimmer on each them you can set the sustain and tone the way you like em and it’ll sound just like a 1322 IC Big Muff. Although I think it’s set for max sustain, as though the pot was turned hard clockwise. The stock tone settings are pretty bad though. icepick or blanket take your pick.

    But where do i place the new pot? in the case, i mean.
    I wounder if someone use it as is…

    Not a whole pot, just a little trimpot. or you could just experiment with different resistor values to mimic the pot at different settings, but a trimpot will let you solder once and then fiddle with it til you get it sounding the way you want it.

    Here’s a pic of a trimpot I put in my 3034 BMP as a noise gate (you’re supposed to remove that white thing once it’s set) so you can see what I’m talking about.

    The LBM has pads for volume, tone and sustain, because it’s a BMP EH1322 board.
    You can kinda see them across the bottom of the this out of focus pic:

    You can see the resistors soldered across them.
    …or pop it out into a NYC RI box and you have an IC Big Muff pi.

    Great idea, thanks.
    What value should i use for the trimpot?

    I think the pot values for a BMP are: Volume, 100k; Tone, 10k, Sustain, 10k. All linear
    Anyone care to verify/refute/provide more detail?
    So, I’d try a couple of 10k trimmers and see how you go.
    In the above pic, both pads are jumpered with 10k resistors, so you could just try different resistor values too in that range.
    What are you trying to do? Less treble / less sustain?
    There’s good info on Big Muff mods here: “http://rkerkhof.ruhosting.nl/Taas/Mods/Big Muff.htm”
    (you’ll have to cut n paste that URL, this board doesn’t handle spaces very well)

    Can anyone help me find the modern-day equivalent of this pedal that EHX makes currently. I want this pedal But I don’t want to shell out $200+. What are the similarities and differences between the op-amp big muff and the vintage little big muff? My goal is to find the pedal that resembles the vintage little big muff circuit the closest while also being affordable. Thanks 🙂
