Lots of power, lots of features, and a very affordable price!
This 2-rack powerhouse delivers everything you need for strong, driving bass, no matter what your style. Think of it as an economy version of the SVT3-Pro. 350W at 4 ohms. 200W at 8 ohms. It features a MOSFET power section and all the tone-shaping tools you need: 3-band tone with ultra mid control and a 9-band graphic. It also provides a balanced line out (pre/post with level selector), an effects loop, input pad, LED peak indicator, and defeatable optocoupler limiter. A variable speed fan keeps it cool.

The sound of the amp was surprisingly good as soon as I hooked it up. I use it for live and recording situations with both a Musicman Sterling (active) and a Fender Precision (passive)bass. I use Mesa Boogie 2x10 and 1x15 cabs (one or both), and the sound produced is punchy and tight with a full bottom and clear highs. The graphic EQ is a nice feature as it allows you to boost at 40Hz for that thick reggae/dub sound or to scoop the mids for a funky slap and pop sound. For the price I paid (used) for this amp I'm quite pleased with the overall sound and features. It doesn't compare to my SVT-5 Pro, but it is great when I'm playing a small dirty club, I only need one cab and want to keep the spilled beer off the SVT-5. It also works well as a back up to the SVT-5 when I'm playing higher profile gigs and don't feel comfortable going without a "Plan B".I should let you know that I blew the power amp out of my unit 2 different times. My tech assures me that's quite uncommon for Ampeg gear, and SLM (Ampeg's factory in St. Louis) took care of the repairs for a reasonable price (the second time the repair was free because it was covered by SLM's service warranty).

I purchased this head in 2003 to pair with an Ampeg 410HE. While the cab is very nice, I would not recommend that anyone purchase this combination. Initially I was attracted to this amp because it seemed very feature-packed for the price. After many concerts, however, I realized that the 200/350 watts were a lot quieter than I had expected. Also, because of its power amp design, this amp's inefficiency great worsens its tone and volume during long gigs. Finally, the cooling fan is so loud on this unit that it is virutally unusable in the studio unless you put the head in a separate room from the cabinet. Of course, the necessary long speaker cable will rob you of your high frequencies. In short, spend a little more money to get a lot more features.

I have owned my B-2R rack head for 8 months and play in front of 150-200 people a week and it has never failed for me. I always recieve comments on it and I love it to death. I play it through a Classic Series 4-10 cab and love it. It has one of the best tones I have heard and has very flexible sounds.
This is a great amp. My only objection is that the sliders on the equalizer can break somewhat easily, so be careful! Other than that, it's great! I use it with an avatar 410, it sounds great. Not as growly or "tube-y" as the SVT-3, but my friend has an SVT-3 and the B2-R is far more reliable. Great for rock, and with tweaking and fine tuning, almost any other type of music.
I bought this amp because of the preamp section. I previously used a peavey MAX preamp, but it wasn't very quiet and the EQ sliders are very sensitive. The Ampeg is noise free and the eq adjustments are clean. I tried it in the store, and the power section is also very good. It was powering a 4x10 stack very well.
This is my first bass head, and it does an excellent job for what I use it for. Tonal options are endless with the graphic EQ, and it's plenty loud. I put it through an Ampeg SVT410HE and it shakes my house! I can finally be heard with the guitars in my band. Highly recommended for anyone who needs more power!
the B2R is a nice head. i really like the EQ it has on the it cause if your pull out (Push the lever down) for everything above 2khz it gets rid of static form your bass. but its a really nice head i have a genz-benz 710 and it really is nice. even tho it only goes so loud, its a good deal. i would recomend it for the your first head. you'll be surprised wut i can do for u.
The only unfortunate thing is that it has no speak on inputs and outputs. The EQ is wonderful to have, as well as the power. I was definitely satisfied with this head.
The head is great if you are using a powerful PA system when jamming with a band or jamming by yourself.
Wow, I played this head through my SWR cab, and I was blown away. It gives you all the Ampeg tone and power you could want, without the Ampeg price. I bought it on the spot, and I haven't looked back yet. I play a jazz bass in my metalcore/hardcore band and I gig with it weekly/bi-weekly, and it holds up just fine. This thing rules!
It's a great head, and now that I have it I think I am going to stick with Ampeg heads for the rest of my bass playing career.
I've had mine for almost a year now. It has been gigged 40+ times and no problems with heat. It just keeps on sounding great! If it ever breaks, I'll buy another one!
