Seymour Duncan Tweak Fuzz Mods

[Ground Control]

I know this pedal isn't highly regarded, for whatever reason, but I absolutely love it.  I have 3 of them.
What's not to love about a silicon fuzz face clone with a pre-gain bass control?  Plus SD did us all a favor by adding thru-hole pads next to all of the surface-mount parts.  It's ripe for modding to any type of Fuzz Face you desire.

One I rehoused into a 125B enclosure (purple box) with no switch to put on my big Boss ES-8 driven board.  I also did the "volume mod" to increase the output level.



One I plan to mod to EJ FF specs with some BC183 & BC183C transistors.  I'll leave the Tweak knob in place in front as it's one of my favorite things about these pedals.

I've stripped the pedal housing and I'll be painting it with some Gold Hammertone spray paint from Home Depot.  I'll probably go with a black mini-chicken head for Tweak and some smaller black hex (MXR-style) knobs for Gain/Volume.  I've never been a fan of the large chicken head knobs as they get bumped out of position too easily.



The 3rd pedal is going to get seriously pimped with a second Tweak knob that is selectable via footswitch.  I find myself going back and forth between a couple of the Tweak settings (2&3) so having this option at my feet will be really cool.  I've also considered adding a couple of mini toggle switches that bypass the small Base-Collector caps on each transistor stage.  I need to tack solder this in and see if I hear much of a difference before I commit to drilling more holes in the pedal. 

Other possibilities are adding an external Bias knob and also the Zvex "Pinch" control from the Woolly Mammoth/Mastotron.

Here's how it will look with 2 Tweak knobs and 2 footswitches.

Painted yesterday.  Color and texture is in the ballpark so I'm happy.

Double-Tweak-Mod in process...

I finished up phase 1 of the double-tweak-mod tonight.
Works great and adds even more flexibility to an already cool pedal.

I'll probably use some of those unused switch contacts to switch between a couple of LEDs to show which Tweak knob is selected.

Pay no attention to the rotated switch PCB...  :oops:
