I have a DC-5 . I don't really use it much because the low end is kind of loose and saggy. With some love , it could be modded but Boogie makes these things with too much plumbing.
One cool mod is to cut the resistor that is in line with teh master volume pot.Info on how to do it and identify the proper resistor is on the Boogie Board forum. All the resistor does is ruin the taper of the volume pot.Once you cut it out, the pot works like it is supposed to.
Voodoo amps is probably one of the few shops that works with Boogies .
