My needs for an amp have changed some now that I am in college. Im consistently going straight into the PA, but I would like to change my setup around so that its versitile. SO heres the skinny. I want to get a power amp (maybe a QSC PLX or something) and put in a small rack that I can use for with my cab (Epifani UL410, not the II model) for when I need my amp. But I want all of my tone shaping/tuner/DI in a small pedalboard. So, the problem is, Im not well versed in what I need to be looking for in features of preamp to be able to tell if it will have the oomph to drive a power amp. I would love to retain a nice tubey, thick sound that I get with my Walkabout, so I was looking at the EBS Valve Drive. I searched around and it seems it can drive a power amp, but from what I could understand, they were being used as a distortion, therefor having the gain up. I want to keep the gain low enough to not be overdriving the tubes. I was also looking at the Radial Bassbone. Would something like this work for driving a poweramp? I know Im kind of rambling so heres the main points. - small (can fit on pedalboard) - at least some EQing options (just for taming a boomy room or something, nothing big...I run flat most of the time.) - can cleanly drive a power amp (having the option of some tube grit isn't bad, Id like to be able to dial some in if I want) - would like to have DI for running to board for house mix too - actual tubes are big plus - tuner out would be nice too - $300ish or less final thought...would it make a difference to run XLR vs an unbalanced signal to the amp? If so, is there a way to have two direct outs (one for console, one for my amp?) Sorry for the long winded post, but Im new to the whole pedal/pedal board thing and I need a little guidance that I couldnt find through searching. Dave EDIT: Also just thought about the Sadowsky pre/DI...thoughts?
