Ampeg B-2R : moosers's user review
The Ampeg B2R is a bass guitar amplifier head, suitable for any kind of use. Where I've used the B2R has been in the studio. The amp boasts 350 watts of power and has a mos-FET design. For connections it has a series of jacks in the back in the form of 1/4" for speaker outputs, and an effects loop, as well as an XLR direct output, which is definitely something that comes in handy in the studio for getting a direct sound in addition to the amp. It also, of course, has a 1/4" input in the front for plugging in your bass. The amp head is also rack mountable and will take up two spaces in a traditional rack casing.
It's not too hard to get used to the Ampeg B2R in terms of it's configuration. If you've got experience with other bass amplifiers, you should feel right at home here as there isn't too much out of the ordinary going on. The main parameters that it has to work with include knobs for gain, bass, mid, treble, as well as a master volume control. It also has a side nine band graphic EQ for further control over your sound. In addition it has a limiter switch to cap it's output and a pad as well. The manual for the B2R isn't something that should be totally necessary.
The sound of the Ampeg B2R is definitely that of a bona fide Ampeg amplifier. Ampeg amps definitely have a particularly full sound and is one that is pretty much synonymous with a professional sound. I like the amount of control that you have available to you, as it's possible to get a number of different bass sounds for different situations. It's not the most versatile in the world, but between the extra graphic EQ and the main controls, you should be able to do pretty much everything you want with it...
The Ampeg B2R is a pretty inexpensive way to get a great bass head. It's no longer being made but wasn't stopped being made all that long ago, so they should definitely be available on the used market for those interested. The B2R could definitely be a nice find for someone looking for a quality Ampeg bass amp but might not have a ton of cash to drop on one. Either way, keep this on your radar if you're looking for a bass amp head.
