After building my first guitar amp last Summer (and it turned out fabulous!), I am now thinking of building a bass amp head. I would like it to be at least 100 watts (more is better) & I would also like to have a pre-made chassis. An XLR out would also be nice to have. I can do the rest of it myself. Oh, and this is important-- I can read a layout really well... schematic, not so much. Any suggestions from the builders in this forum?
