OPTIONAL MOD IDEAS
Battery clip to 9v adapter http://www.voodoolab.com/shop/index.php?cPath=22_24_40

STEP 1: Remove Hardware and Prep Things
Remove back plate - Philips head screw
Remove knobs. Flat head screw driver
Remove pot hardware
Label Pots for memory :-)
Unscrew PCB - Phillips head

STEP 2: Change volume pot from 470k-A to 500K-B
(More powerful volume taper / slight eq effect)
Mount 500K-B into case. Use plastic washer from OG pot (#10 Socket)
Unsolder one wire at a time from OG pot and solder on to new mounted pot

STEP 3: Fix OG Fuzz pot internally
(IMHO the fuzz pot is useless. Max it out and mount it inside. Clean up with guitar!)
Place hardware back on just in case you ever want to reverse this mod
Mount with two layers of 3m tape or hot glue

STEP 4: Move VR2 to external Fuzz position
(Gives an external adjustment of the bias control! So much better than the OG control)
Heat single leg of trim pot and gently lift
Take two wires and strip ends
Tin the wire
Place heat shrink on them (optional)
Solder top left pad to lug 3 of the 10K-B pot
Solder bottom single pad to lug 2 of the 10KB-pot
Mount the new pot into the old FUZZ spot, use the plastic washer from the OG pot
This pot adjust the voltage to the collector of Q2
The standard setting for this control is 4.5v (DMM)
Lets you go from gated fuzz / normal fuzz / stronger fuller tones

STEP 5: Replace R2 20K and VR1 trim pot w/ internal pot
(Even more adjustment of how the stages interact. Using a full size pot for ease and also lets you drill and mount externally if you are a little crazy….)
Remove VR1 gently from PCB
Jumper across the old VR1 pads
Unsolder R2 from PCB and remove
Take two wires and strip ends
Tin the wire
Place heat shrink on them (optional)
Solder one wire into old R2 PCB hole and then to lug 3 of the 1 MEG C pot
Solder another wire into the other old R2 PCB hole and then to lug 2
Pot down is 1v ish (stock setting)
Pot up is 8v ish (kills sound completely)
Barely backing it up will jump down to around 3.5v and give you some unique tones

STEP 6: Place the backplate on
STEP 7: Pick knobs: https://amzn.to/2KzhXD7
STEP 8: Sign it, date it and be proud!

OPTIONAL MOD IDEAS
- Battery clip to 9v adapter
- Change out transistors with other NPN Is types
- Step 2,3,4 will work on virtually ANY Fuzz Face!

TONE TIPS:
- Guitar directly in…. NO exceptions
- Fuzz is an instrument. Play to it not with it.
- Experiment with your guitars volume
- Place a Tubescreamer after!
