Hello everyone. This is my first post at talk bass. I've read thru many postings and am happy to have something like talk bass to hear from like minds. I have a question. I'm in the market to buy a new head for my Ampeg Classic 410HLF 4ohm and I need some advice. I have the cash for a new head but and split between the Markbass Little Mark 800 Bass Amp Head, the Markbass III, or an SVT4-PRO. I am tired of heavy amps and like the idea of portability, but from what I've read, everyone who uses micro amps do so for 210's or 212's or 115's. The 800 can give me headroom on my 410. I've had repair issues for 500w amps in the past and outdoor gigs with no wall behind you leaves me hard pressed for sound with my old 500w amp. I'm leaning towards the SVT because it has 2powered channels for possible extension cabs and I have a MESA powerhouse 1000 that I could use with the SVT. I can get one of the three and the more resarch I do, the more undecided I get. I want to get into newer gear like I micro amp, but I NEED SOME ADVICE.
