hey pros i need some straight talk. I have read lots of opinions of how a Genz Benz head is an 'upgrade' over lots of the other commonly-loved equip. in the past week I had opp. to play a NeoX 400 combo  and a GBE 400 talking to a big Hartke 4 x 12 or such cabinet [not sure, but it was big]. in both cases I had similar thoughts [and I play a Sterling if it matters that much] - a Lotta volume.... both amps could get real loud in a hurry - almost too balanced with all settings flat. frankly sounded like a good clean guitar amp with all settings normalized. I was looking for some bass - with the "Extension" kicked in I start hearing bass. Then by running up the low end of the EQ it starts sounding good. - But with everything tweaked as best I can, I would not describe either amp as either "Warm" or "punchy". I can get midrange punch. I cannot get low-end punch. The low-end still sounds 'slow' to respond to me. Not as whooshy as my SWR, but still not a PUNCH. Nor is it as transparent and overly-clean as my old Eden. Its got some aggression, but ......... I keep thinking I need a tube-hybrid but maybe I'm over-expecting. the Yorkie XS400 I just sold [too cheaply] had a lot of bottom, but no punch to speak of. yes you could make it muddy/bassy by running up the tube overddrive, but it was just that... a lotta mud being spread across too long of a time segment. Low-punch is what i need to balance the natural mid/high of the instrument. I had been told Genz Benz was the way to go. Do i need to look at their High-End equip....??? am I doing something wrong? Should I be looking for a good 4-ohm cabinet instead of a head? this is annoying.
