Hey, everybody. I am looking for a small combo amp with an extension speaker output. I'm interested in the Gallien-Krueger MB150S/112 combo (the one without the chorus effect) and either the Polytone Sonic Bass I or Mini-Brute III/IV/V. I'm pretty familiar with the GK sound, but what are the Polytone amps like? I would like something a little less harsh and aggressive than the Gallien-Krueger. Do these amps have similar volume or will one be louder than the others? Any of them have a significantly greater low end presence? Thanks for your time, guys and girls.
