Yeah honestly the price of quality amplification is really high. Some of the cheap stuff can surprise you but that GK I had couldn't keep up with my TC 115 and its also a cheap cab (converted from a bg250 combo) I really would benefit from sucking it up and getting something nice. I can't justify it right now. I might be able to if I start looking for more gif opportunities.Those were a budget line with some el cheapo speakers in them.
A decent quality 410 or 212 with 200-300 watts to hit it with is pretty much the standard for carrying the room at your typical local bar with a few dozen noisy drunks in it.
