Big Muff w/ Low-pass

[Thunderscreech]

I had a thought about a Big Muff with a low-pass filter on it. has this been done?

[thombo]

it's cool... the sustain in the muff can make for a synth like sound when pushed into the lpf, though it can be hard to control. it will sound more like a synth lead, not the grainy muff sound.
i like the sound of a lpf before the muff. the lpf will act like a noise gate, minimizing/controlling the muff sustain. the sound is basically a bassballs w/ more knobs to fine-tune with.
*i use a moogerfooger mf-101 and a little big muff

[thombo]

it takes up a lot of room on a pedalboard too.

I sorta meant a little LPF modded inside the muff, like a hax of some sort

i don't know what you mean, both "hax" and 'inside the muff'... are you saying you want to add a lpf somewhere within the actual circuitry of the the muff?

i know bass->lpf->muff->amp, and bass->muff->lpf->amp.
i can't even conceive of bass->part of muff->lpf->part of muff->amp

you're getting into some weird electronic stuff. it might be a fun project if you get a diy muff diy lpf kit. i would caution, b/c of the different stages of circuitry in a muff, the placement of the lpf might sound drastically different depending on it's placement inside of the muff. also, would this take two different power inputs or just one?

I just changed the tone stack on my GGG-tuned Big Muff and added a mids knob. With the mids knob maxed, I get a mid boost when the tone knob is at 50%. The lows are also boosted slightly from where they are with the GGG-tuned values. Along with the jumpering of the first diode pair, I'm getting good low end and plenty of mids.

The tone pot on a Big Muff is essentially a blend between a high pass and low pass filter. If you go rid of the low pass then you'd loose most of the fuzz from the pedal.

That's my thinking. John Davis mentioned in another thread (I think it was your thread rcubed) the possibility of a fuzz with a blend where the clean signal was sent through a low pass filter.

I think THAT would be a cool idea.

But sending a fuzz signal into a LPF or sending a low passed signal into a fuzz would just kill the fuzz sound almost completely. I do this now intentionally with an expression pedal controlling the cutoff of the Moog. Starting around 60 Hz the fuzz is not even noticeable. But as the cutoff is raised the fuzz starts to be heard.

Do you mean an envelope triggered LPF, or a static LPF?

+1 to this whole thing. That thread had me thinking that a a fuzz with a clean blend, and a lpf on the clean side, would be my kind of a 'synthy' fuzz- a muff or something gated would be great.

Happynoj - I'm pretty sure the OP was talking about a static resonant lpf, as that was the topic of discussion in rcubed's thread, and what a good topic!

i know realize that this is where my suggestion went wrong.

I guess rcubed will get to it before i do. I have no funds at the moment.

I'll add that to the lists of projects to work on. I want to figure out the Cream Pie circuit next (I'm really close) and try some mods to it based on some complaints I've heard.

Slap my face and call me Sally.

If you get that one worked out be sure to drop me a PM. I'd be very interested.

You know what I'd like more than anything? A really bassy, gated fuzz that worked well with actives. Like a Mammoth but with more character. That's what I've been looking for forever.

It seems like all the good gated fuzzes either don't like active basses or if they do they are too nasally/not focused enough in the bass range for me.

Funny you mention a Mammoth that works well with active basses because that's on my list to do. And I'm pretty sure I know how to do that now.

Seriously, if you get some of this stuff built and are willing to build for other people, let me know because I'm definitely interested.

Will do. I'm sorta using this thread as "blog" about what I'm working on and plan on working: R³ Effects

BigO, have you tried any of the Devi Ever stuff? She has a few different gated fuzzes, and they have all played nicely with actives in my experiences. Maybe they're not the tone you're shootin for, just thought I'd throw that in

[Jared Lash]

Actually I haven't.

I was actually under the impression that Devi's stuff DIDN'T play nice with active basses.

But if they do, then I've been missing out since I've dug a LOT of DE clips on guitar. Is there one that you know of that is both really bassy AND gated? If so, I'd like to check it out.

Well my main bass is an active Carvin, so I feel confident saying that they play just fine with actives. I did a review of the Bit about a year ago with a bunch of clips, which is a good starting point, as that one is really gated. I would also check out grygrx's review of the Devi Bass Fuzz, I think he has some clips with an active bass on there. The 33 is also gated, but I know of no bass clips on that one. Also, the OK is very gated, and I can try to whip up clips of that one in the next day or two.

EDIT: Here is that thread of the Bit

Yup, I've got a mod that I'm tuning as well. So far, so good.
