Oh, but wahs are so fun!Less is more ... or Leslie is Morley or something.
Honestly can't think of anything else that's needed. I'm not Bootsy therefore no wah/filters are required, I'm not into reverb or delay, and I have all the dirt I could want courtesy of my amp (or the VT should I be going into solid state amplification).
@Stevis - The Morley pedals were always big. That pedal has a drum full of a really toxic oil which is probably no longer legal to buy/sell. And yeah, heavier than a lot of Class D amps....
Update: More here Mondo Morley Medicale: RWV Rotating Wah – Doktor Ross Sewage
Of course I also run some weird pedals, so there's that.
Also Ross is the former bassist of the disbanded Ludicra, a fantastic local band from around here.
