Making a GGG Fuzz Face (70's option), what mods do I need ?

[surfingbird1]

I am building the ggg fuzz face late 70's option.

I want to mod it for bass, but I dont want floppy lows, who has any thoughts.

Also, what should I use, silicon, germ, combination of both?

late 70s schematic!!

thx in advance

It depends on whether or not you have an all tube amp. I easily get loads of low end out of a Fuzz Face with whatever cap values are in the Dunlop Jimi Hendrix Fuzz Face, but folks with solid state amps seem not to.

And if you have a solid state or hybrid amp and/or active bass and/or any buffers of any kind you plan to place before it and/or a sansamp you plan to place after it or anything other than a high output passive bass, few if any other (true bypass) pedals, and an all tube amp you can crank into compression, I highly recommend a "permanent off" mod, so that the pedal won't engage, ever. Fuzz Faces require particular gear to sound good, and particular playing technique at that. It's not just an overdrive box that you can throw in anywhere with any gear and some people will think it sounds good.

the "permanent off mod" means dont build it right, i dont speak fecetian very well, but I have seen many fuzz faces modded for bass, the ox fuzz, etc

I have active emgs in all my basses, I have a sansamp, I have a hybrid bass amp, so now what are my options?

I am building this thing its in my house as we speak, so its happening, I am just curious what I can do to make it better suited, I am comfortable with a soldering iron

thx

Yes I was being facetious haha! Well if you're insistent, check the size of the input and output caps, if we know what they are then we will know whether you need to change them.

If you don't want floppy lows, I find the caps in a regular silicon Fuzz Face to be just fine, so you might be ok. Depends on what you've got there.

Just be aware that there's a good possibility that you're going to hate the sound of this thing when you complete it, and that's not the pedal's fault. It's really not designed to be used with the gear you're going to be using it with.

Just socket a few key spots in your layout and TRY it with different values and components.

I doubt anyone here can help you more than that.

See the previous posts to prove my point.

+1! That's the beauty of DIYing! Try lots of different combos until you hit on the right combination which works for you. Problem is, you'll have plenty of "failed" experiments. Believe me, my pcb graveyard gets bigger by the day....

Well if the OP was playing an amp like mine, a .047 output cap might do the trick as it has for me, and I suspect that's what the kit came with, but others who have tried the same pedals through solid state amps found that wasn't enough so he'll probably need something bigger.

Mark, if you're referring to your "Your Face", it's got a .1uf out-cap.

[Wren and Cuff]

Also, for the op. Your active pups on your bass are going to make the fuzz face sound frizzy and unpleasant. If I were u I'd pick a different dist to start. There are many cool projects that'll sound great with the emg's but the FF probably won't sound so great. Purely my opinion. Good Luck!

This is something you might want to read up on to help with the problem previous poster's are warning about.

Also, if you're up for adding more knobs/trim pots, research the Woolly Mammoth. It could give you some mod idea's.

[vigor&kandor]

do the 'zvex mammoth' mod.

Right yeah I figured that had a bigger cap, but I was referring to my Jimi Hendrix Fuzz Face, which I use for the silicon sounds. But to be honest I'm not certain what's in that either .

[Wren and Cuff]

I believe you are correct... May have to steal your bass face samples BTW!

[Mark Olson]

Sure, I've got them in .wav if you'd like sometime. I've also got one that I did with flats/fingerstyle for something different. I'll add that on my thread now.

[surfingbird1]

ok so far this is what I am doing, I am doing the woolly mammoth bias mods with an input pad for the impedance issues, and the beavis audio phat mod (switchable of course), and a yellow LED

[Mark Olson]

Just so you know, a simple input pad will pad the input, but unless you have a buffer converting your low impedence signal to a high impedence signal more like passive pickups you're still going to have the impedence issues people experience with Fuzz Face based circuits (like the Wooly Mammoth) with active pickups.

[rcubed]

Make the input and output caps 0.1uF at the minimum.
