I just picked up an Ampeg valve pre-amp, which is just great. (I tried it through the Fx Return of a MarkBass.) The problem is I now want a 2nd (for stereo). I might pick up a SansAmp one to tide me over.   I think the pre-amp can make a big difference even in a home setup.   That's interesting - I'm just looking at those; I've been thinking of the 4-channel one, so I can put synth pedals through it too. I'll probably go for one at the end of the month. Wha
