    Yes there will still be very subtle tonal changes as you adjust the tone knobs, its insignificant IMO.
    You can completely bypass the tone stack but its a lot more work.

    I’m about to mod my Black Russian Big Muff (Black -> Green), and I have one key question: I know the resistance value of the three resistors I need to obtain, but not the wattage. Could you help me?

    1/4 watt.

    Resistor Mod for Big Muff Pi.

    I know most people increase the resistors as part of the Creamy Dreamy mod. Does anybody know what value to replace them with? Thanks,

    Here’s good list of resistor values for different Muff versions from the BYOC cloners http://www.bmfeffects.com/byoc_large_beaver_mods.htm

    All my big muff and other pedal mods links are updated and working! (Sorry it took so long)
    :)

    ATTENTION BIG MUFF MODDERS!

    I noticed a mistake (due to lapse in concentration likely) in one of my diagrams. The directions were correct but two wires were backwards, it is now fixed.
    I advise anyone who has used the following diagram (now corrected) to check the work you done and fix it if need be. Sorry about that!

    Just to be safe I have also gone over all the other ones I posted and they are fine.

    Kind of off topic relative to previous pedals mentioned on this thread, but still within the realm of the thread’s subject matter. I’m planning on adding a jack to my Stereo Polyphase to allow for expression control of the rate. Does anyone know the value of this pot? This will help me find an expression pedal which I can take full advantage of the rate sweep with. I also asked this in a separate thread but thought it might get more visibility here ;).

    You may be able to email EHX about it: info@ehx.com.

    The EH man will likely know though.

    hello guys,
    i’m going to be getting a holy grail in the next couple of weeks and was wondering if it was possible to mod it to have a battery, if i’m not mistaken its only dc useable.

    Anyone else having problems uploading the pics from the small stone “blend” mod? They won’t open for me.

    I’m trying to get an idea of how to mod my DEM RI with a blend control, tb, and possibly volume drop. Anyone know how I would go about adding a blend control to it? thanks alo!

    So, this is my first pedal mod EVER so just to be clear here:

    I think my initial confusion is just coming from not being entirely clear on how a dpdt switch breaks up a circuit.

    I want to do the tone bypass mod on my Russian muff. I know I run a lead from one leg of those two components (a resistor and capacitor, I forget exactly which ones right not) together but then……

    Could I put the combined lead onto, say, the first lug of the dpdt switch? If that were the case, what other lugs would then be used to reground the two components and cause the tone circuit to function normally?

    Also, how is it that these two components are bypassed by being ungrounded if they are still connected to the PCB? Do you clip a leg?

    Pardon my ignorance on all this. I haven’t even bought a soldering iron yet.

    This should help. Let me know how it works for you. http://www.beavisaudio.com/techpages/BigMuffToneControl/

    I have been speculating the possibility of the modify the little big muff and make a bridge between the input jack and output jack for a get a clear channel, and use the volume as a blend, the idea is to do the same as the bass big muff …. I play guitar and bass and use the little big muff for both …. my question is, how can I do it? there are some precautions that I should take? … can I use the volume as a blend ?…. what are the bedst materials should i choose to use?…. have you some recomendation???…etc etc etc
