We gig this one and I just dig in with my valve pre amp peadal and valve rig and it doesn't sound right to my ears, I think the cheapest option would be a fuzz pedal, something like an MXR bass fuzz deluxe, but I can't really justify it for one number, I hear there was a lesley speaker involved, and a pick, someone recommends a digitech ventura vibe as well, there's some stuff here
