I'm a little confused. I have bought this head with a 4.5xl and a 1x15 xl aout one and a half years ago. At the beginning, I really liked the tone, much punch etc. but i've recently bought a 30 watt ibanez soundwave combo. Now when comparing the two heads on the Hartke cabinets, I find that the HA 5500 sounds like **** compared to the ibanez (which cost me 400 bucks less than the hartke head alone). Am i simply not able to eq my head, or does it have this cold, powerless characteristics that don't allow the slightest amount of growl? What I'd like to hear is : 1) What could I try to do with the eq? 2) What other heads (300-500 Watts) would you recommend me for little cash?
