*True Bypass Mod
*Volume Boost Mod
*Wah-Volume Pedal Mod
After having completed all of these mod and a few others I recommend doing them one at a time and testing in between mods so if you don't like something, you can easily reverse it.
Your gonna need some basic soldering tools...
-good soldering iron (mines a Weller WESD51D I got for christmas)
-helping hand (a must!!)
also the to wire anything to the board itself you will need 24AWG wire
Step 1: Research
http://www.geofex.com/- click "FX Technology
-Technology of the..." in the upper left
These are some pictures I found useful...
Step 2: True Bypass
I chose to remove the input buffer because it seemed to be the most easily reversible and from what I read, sounds better.
1. Open up the case and remove the circuit board.
2. Desolder the components.
3. Desolder the switch.
4. Install the new switch. (i used a 3PDT switch. Check out ebay for good deals)
If you use a 3PDT switch you can also add an LED to you pedal but I didn't want to.

Step 3: Volume Boost
Step 4: Wah-Volume Pedal
I got 50 of these babies on ebay for $10 w/shipping.
Step 5: Vocal
"Replace the 33K resistor... with a 68K. This gives a more vocal quality to the wah. Some Vox Clyde McCoy wahs had 100K resistors here." - http://homepage.ntlworld.com/s.castledine/greenfuz/wah.html
I decided to go with That_Pink_Queen and use a 100k ohm lin variable resistor so I could dial in the sound I wanted. Or you can mess around with multiple resistors and a rotary switch. Your choice.
Step 6: Midrange
So I replace my 1.5K (1k5 same thing) resistor with a 2.2k. Sounds fine but I since I did all my soldering in one go and the removed what I didn't like I cant say weather or not the difference was noticeable. Try it out for yourself.
Tip: Save all of the components you remove and store them in a container. That way if you want to change something back... you can.
