Dunlop GCB-95F

[kanyonerro]

I have a Dunlop Classic Wah, this is my latest search for THE wah.
This unit is close, but find it too "thin" and without much punch when fully depressed.
Are there simple changes I can make to tweak the tone/drive?

Thanks

You will need a schematic unless you have the circuit verbatum. Try this. Many of us use this as our wah circuit bible.  http://www.geofex.com/article_folders/wahpedl/wahped.htm

There are many places on the web. A good place to start are aron's link's:  http://www.diystompboxes.com/wiki/index.php?title=Links

Good luck with you search!
