I'm saving up the bucks to buy an amp good for slap playing, and would appreciate your suggestions. I tried a new SWR Redhead at my local music store--but I figure I should scope out alternatives before I drop the dough. Your thoughts on good quality/high value cabs and amps? (I'm using fretted MTD import basses, 4 and 5 string.) And any comments you have on speaker sizes and cab configurations are helpful, too. Thanks.
