So, I have room on my board for one more pedal, and I was thinking I would make it a Zvex Wah Probe. Interesting effect, fits in the space left, etc. However, thinking about it a bit more, it looks like the Subdecay Prometheus DLX would be able to emulate a traditional wah (with an expression pedal) as well as many, MANY other sounds. Does this sound right? Will you justify my purchase oh forum?
