My ZX arrived today!!! The Dark Crimson Rock Maple is just awesome!! Now I'm gettin' down to business!
The plan is to use the K4 for small gigs - bars, nightclubs, usually a single or duo where the other guy in my set has a small powered mixer with some EV Zx90s. The Zx90s have enough kick for his guitar and my SPD-20. I will be switching from the SPD-20 to a MBP using Superior through a MOTU Ultralite. I think I should be ok, but just in case, the K4 also has a sub out. If I need some extra low end I may look at a QSC KSUB. When I play with my band, none of this is an issue since we have a larger PA with EV cabs and subs and an Aviom monitor system. I may not use the K4 at all with the full band.
