Mutron is a Moog-Fooger pedal that's like a guitar synth. Wa-wa, is what I presume to be a wah pedal.
2005 Epiphone Les Paul Custom
Marshall JCM900 MKIII Master Volume head
Carvin G412T cabinet
Line 6 DL-4

Boss CS-3
Boss NS-2

Ibanez TS-7 (being modded soon!)
Mutron could also refer to the company, which made wahs and auto-wahs.

Essentially you need a wah of any type.
