3rd times a charm

By Larry Lytle

from Montana

The B450 MK2 is a pretty good amp. It works very well with the B115 MK2 cab, two 115's would be even better. I like the overall quality of the amp. It does well with my electric bass as well as my Upright string bass. Just be careful when you get the amp from UPS. The first two amps were not handled well at all. If the box is ripped or has any gouges refuse it. Play the amp and make sure it is good before you get rid on the box. The first amp had a bad buzz when played, the second had a bad speaker, The third was fine. I recommend this amp to anyone. I received excellent service from Guitar Center. Be sure to get the extended warranty. Its the best UPS protection you get.
