I have the VT Deluxe....one can preset 6 different sounds with minimal tweaking. I have mine set for the SVT sound, the early Geezer tone, a clangy tone, and a John Paul Jones mid seventies sound. And of course completely overdriven sound.
Right now it's just a preamp/ overdrive pedal, haven't had a chance to use it as a DI.
Love me a P-bass!
