Why aren't more companies making any little combos that are similar to the GK 150 MB? I mean, it seems like that is the only thing out there like that. Does anyone else know of anything that has that volume, weight, size, quality? Sure, its not the greatest all the time, but its practicality beats everything else out there that I know about. I would love try out some other amps that are similar, but it just doesn't seem like there is any competition.
