I modded my V847 to true bypass with a Carling 316DPDT switch. Wah sounds much better now but....it is much louder when I kick it on. Major volume boost. I've read some of the wah mod pages and people have suggested changing an "output resistor??" but I'm not too clear on which one or what value it should be changed to. Again, when I kick on my V847 TB Wah there is a significant volume boost which I want to get rid of. If anyone can help me out with this technical issue that would be great. Thanks in advance.
