Tweak Fuzz Double-Tweak Mod

[stilwel]

I own 3 of these Seymour Duncan Tweak Fuzz pedals.  I love them so much...absolutely my favorite fuzz box.

I sacrificed one of them tonight so that I could do a double-tweak-mod to one of them.  Added a 2nd footswitch that selects between the 2 different Tweak knob settings.  Makes an already super-cool pedal even more flexible and useful.

Cool mod. I always liked that pedal, should have bought one years ago rather than building and buying a bunch of different fuzzes to figure out what I like.

Cool, I always thought the Tweak Fuzz was a cool concept. The other fuzz faces and clones have replaced it for me, but I like the input cap selection.

Any pics of the whole board? How is that Boss ES-8 treating you?

The ES-8 is amazing...although not without fault. There are a couple of things I'd like to see changed in the firmware and they way they handle going in/out of the modes, but they aren't deal breakers. Loving it so far.

Here's what my board looked like up until very recently. I'm going through a slight re-layout this week.
The purple box top-right is a rehoused Tweak Fuzz. I'll be putting my double-tweak-fuzz on the board in the place of the H9 and need to make room for a Zoom MS-70CDR somewhere.

Yep, super cool pedal. It's totally holding it's own against a good selection of fuzz boxes that I have on hand right now. The Tweak knob makes it so versatile.

Re: Tweak Fuzz Double-Tweak Mod

Cool! Love the fuzzes.

Is the Boss doing patch changes in the Line 6 as well?

Re: Tweak Fuzz Double-Tweak Mod

Yes, it's sending MIDI program changes to the H9, M9 and M5. I can also use the EV-5 expression pedal to control any of those 3 pedals.

Quick clip using my Tweak Fuzz over the weekend.

Dang artie
I didn't realize there was so little to a fuzz circuit

Surprising, isn't it?

Of course, the fewer components, the more detail is required for selecting those components. It's a great circuit for experimentation though! Component spec variance is the reason some fuzz faces sound amazing, some sound awful and most are good. When you get into slightly more complicated circuits like a Tube Screamer or DS-1, tolerance plays less of a role and the majority of the pedals sound consistent.

Re: Tweak Fuzz Double-Tweak Mod

Yeah. The complication in an audio circuit is making it clean and flat. (EQ wise.) Making it dirty and colored is the easy part.

Re: Tweak Fuzz Double-Tweak Mod

I should play through mine again, I bought one off here used that has the volume mod. I guess stock it super quiet for some reason? Not sure why they made a pedal that required clipping out a part to make it more usable. Anyone know the story on that?

Re: Tweak Fuzz Double-Tweak Mod

No mods are REQUIRED.

The Tweak Fuzz is no quieter than a regular Dunlop Fuzz Face. Unity gain is at about 3 o'clock on the volume knob. At max volume it gives you a little bit of boost.
It's perfectly usable as-is, but if you want/need more volume it's an easy change to make.

Let me know if you're interested in selling yours.

Re: Tweak Fuzz Double-Tweak Mod

thanks for the info & will do!

Re: Tweak Fuzz Double-Tweak Mod

mine had a volume drop when engaged unless the level was wide open
the volume mod corrected that
replaced a resistor and jumped another

the mods made mine much more useable

Re: Tweak Fuzz Double-Tweak Mod

I added an LED so I can tell when the lower Tweak knob is selected.

I'm like a crazy cat lady, but instead of cats it's Tweak Fuzz units. The gold one is an EJ FF (BC183) with an external bias pot. The left footswitch is bypass and the right switch will select between 2 preset input caps. I need to come up with a plan for the lower-right unit.

Re: Tweak Fuzz Double-Tweak Mod

That is some really good EJ tone...nice!

Hi ArtieToo.
Thank you very much for your electronic scheme which is the only one I found on the internet for the tweak fuzz. I'd like to make one by my self, but the C1 value is missing. I've seen pictures of this capacitor but it's verry small and I can't see anything, could you help me ?
I'd realy like to have this Fuzz and it's imposible to find it in France.
