I have read lots of threads here about Hartke stuff - both positive and not so positive. I have one of the older 3500 Mosfet heads and a similar era 4.5 XL cab. These were regarded as high end stuff back then. Now I see Hartke stuff selling for next to nothing - and I'm not sure what happened to them - but my rig puts alot of other gear to shame IMHO. I have thought lately about "upgrading" to Ampeg or Eden - but the rigs I have tried aren't any better sounding than mine. What is the real scoop with Hartke ? Does anyone know ?
