I've read somewhere that you can easily make the wah pedal into a combo wah and volume pedal. Is this possible? I like to learn more about that. Have anyone here ever tried or done that? What's the result like? Does the volume affect the wah and vice versa? I wanted to get a decent volume pedal and if that option is possible with decent results then I'd like to turn my wah into a volume pedal as well. Thanks in advance.
