[quote name='burno70' post='254333' date='Aug 4 2008, 01:02 PM']I use a Fulltone bass drive to add grit to my tone. Comp mode is excellent. Although some users find the volume switch a bit too sensitive.[/quote]
if you'e willing to spend the dosh, then go for a fulltone bass driver, or maybe an xotic bass bb preamp pedal.
both are excellent.
