I just picked up a Hartke HA3500. I tried it at practice last night through an Ampeg 4x10 and a Peavey 15". It was in a small studio room and the speakers were crappy studio gear plus it got pretty loud in there so I'm not sure about the sound. It sounded OK while warming up. I liked it in the store through the Transporter 410 and a Fender 15. I'm going to gig it on Wed and Thu this week through an older ampeg 2x15 and a 2x12. If I'm not happy, I'm going to bring it back, wrapping and all, and move up to a nice 400 watt Trace Elliot they had for about $200 more. Or I'll exchange it for some speakers and start from scratch. I got the head for about $450 so I thougt it was a decent deal. It's got straight solid state and tube emulation that you can blend with separate pots, a "room" adjustment which is kind of like a presence knob, a parametric with (I think) 7 or 8 band, low and high pass knobs, and a compressor knob. It had nice tone for what I do. Plus the price was right. I think it will be enough fire power for me, I wanted to hold some cash in reserve so I wouldn't have to skimp too much on cabs (which will be next). Let me know what you think. I hear Hartke doesn't have a good rep here. Plus, it's the most common used head I see (which either means it sucks or it was over hyped and kids bought them only to return them for cash to support a drug habbit). My impression was that it was a little better then "good enough".
