    Comments about Acoustic B450mkII 450W Bass Combo Amp:

    This is one kicking good size amp. I purchased the 410 Cabinet and now I have no problem at playing any gig. I will not be over powered by my bud on his guitar. Love the punch and bottom end. Might add the 1-15 cabinet just for more depth. I love it I play Les Paul Bass and a Rickenbacker does great with either one.

    3rd times a charm

    By Larry Lytle

    from Montana

    Comments about Acoustic B450mkII 450W Bass Combo Amp:

    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.

      Comments about Acoustic B450mkII 450W Bass Combo Amp:

      Great sounding amp. Completely blown away by the punch and power of this thing. I rarely get it turn up past 12 o'clock, so plenty of headroom. Generally I keep the gain and volume at around 10 o'clock and the EQ straight up and play with either a Fender Jazz or an old Peavey T-40. Had some issues with hiss, but I believe that was because I had a pedal power supply plugged into the same outlet. Fixed with a power strip. I use it at church, so some of the stage lights could have come into play there too.
      There's plenty of EQ control built in that I like. The built in compressor isn't bad and I like that it has a mute switch. If you use an active bass, there's a -10dB pad, which I like better than having a separate input for actives. It's also a perfect hight to sit on top of during practice (I play a T-40 a lot. It gets heavy. This feature is important to me. lol)
      Overall, a great sounding amp and very well built.
