I picked up a hughes & kettner tube factor pedal yesterday and I think it's the best overdrive pedal available for bass. Allodox is a huge supporter of this pedal and I see why They aren't cheap (I bought mine new for $219), but it's definately worth it. Has a real tube and dual footswitchable gain stages. Huge bottom end, huge tone, lots of smiles I have an active pre on my main bass now and I'm contemplating using this as a preamp (has enough output to push a poweramp). The tube clarity and warmth give me the exact tone I want, and the extra gain boost gives a clear, bassy, growling overdrive. Anyone else use one?
