I recently joined a 70s rock band and have a question about the MB150S. I have a chance to buy one along with the matching extension cab and wonder if it will keep up with a drummer. This band is not real loud, so wondering if you guys with experience with this amp please share. I am interested in this amp because I mostly play upright and the reviews are very positive on this amp for upright so I think it will be a good fit when my Phil Jones Flightcase is not enough. Thanks in advance.
