Bass Big Muff ~ Blend pot.....

I want to do a big muff for a friend, he's a bass player so I think a blend pot would be a very good mod for him. I've looked at the fender blender schem and thought that this may work:

(schematic taken from www.generalguitargadgets.com, modified by me, if you want the real schematic go to ggg. I reprinted for reference ONLY, not trying to say it's mine or piss anyone at ggg off, they're good people)

The fender uses a 5k pot. would this work here? If not what would be a good pot value?

Also what should I do to the tone stack to make it work well with bass. I figure a flat eq would work great, i'm going to put the tone pot on the inside w/a trim pot so the blend knob is going to be on the outside. I'm going to use the ggg kit.

Thanks!

I like this question. I'm also curious about the blend pot.

Also, I just made a BYOC Muff Clone and modded it to have switchable mids (scooped/flat/boost).

I have yet to try it on bass, but i think that more versatile EQ would be helpful.

Bump.

I think i've read somewhere that Keeley does a "sparkle drive" mod to some pedals, tubescreamers etc. Where it incorporates the ability to mix in the clean.

Ill bump this, good questions!

it can be done, and i'm not 100% sure how. BUT.... if you're building one from scratch, you may not need it. i just got an old green sovtek big muff, and it has every ounce of lows intact, even at high treble tone settings. not sure why the old sovtek's are better on bass, and i didn't believe it until i tried... but oh man. blows my NYC reissue out of the water.

looking at that picture you posted, if im not mistaken you just running the output back into the sustain section, which is past a gain section. If you wanted to blend a clean signal in, woudlnt you want to blend in the original sound of the bass from the input? and blend that with the output?

Yeah, but wouldn't there be weird volume issues or something?

Rather than mod the Big Muff, I would recommend taking a different approach. I just got through building the Splitter-Blend at www.runoffgroove.com and I would HIGHLY recommend it. I'm a bass player and it's good for that, but it also makes a really cool tool for guitar players.

Basically it provides two parallel buffered effects loops with a pot that pans between them. You can leave one loop with no effects plugged in and that will give you your clean blend. You can use it for your whole effects chain and you get nice unaffected tone combined with effected tone.

For guitar, the uses are endless. You can do two trems in parallel, or a trem and a wavery phaser. Fuzz and clean. Compressed and raw. Wah and clean. Wah and auto-wah. LOTS of possibilites.

Try it, you'll like it!
