I have a wah that I built using premium parts and is true bypass. It has the BC109B transistors and a 4-DIP Switch (ala Teese RMC3) with Polystyrene capacitors to change sweep frequency. Metal film resistors and trim pots to adjust Q, mids, lows, and volume. I have a Sagittarius Halo or a Red Fasel to install in it. Clear blue LED on the side. Enclosed Switchcraft jacks. Potentiometer is an ICAR 100K Black Bear... a good pot with the right taper is important. Filtered DC power jack circuit. Basically everything you would want in a wah. It has an option on the board to wire two inductors later if you want. I can post pictures if anyone's interested.
Asking $175
