    Anybody use one of these? I'm considering buying one but using my Sansamp RBI through the Poweramp in. Any info good or bad about this amp will be appreciated

    The B4R has the same tone section of the B2RE and the SVT 350 - so if you like that sound, you will like the B4R.

    I used to have one of these. Sounded great (IMO) loud as heck but I got tired of lugging it around. (Heavy)

    If all you are going to do is use it as a power amp for your sansamp, I would suggest taking the same money you would spend on the B4r and head over to Carvin and buy the biggest baddest power amp you can with your money. While you are there, check out that 1500 watt bass amp they sell. That might be something else worth considering.

    I had a B4R until it was stolen. I ran a sansamp RBI in front of it in the exact same manner which you described. I played an american jazz through it. It had a nice drive and a good mid-bite, Excellent slap / tap setup.. My only complaint was that it lacked lows.

    if you plan on only using it as a poweramp anyway, may as well save money on a dedicated poweramp unless the b4r is a really cheap deal or something.

    Forgive me but isn't this a pointless excercise?? If you want to use a SansAmp RBI why buy a head? Just pick up a power amp and you're good to go. I'm not sure how much you would pay for a B4 but Carvin sell their DCM1000 for around $300 IIRC. That's a 1000W!

    The B4R lacked low end? Highly unlikely. It's most likely a weak point in your rig somewhere. The B4R can put out LOTS of low end. I don't know how 45lbs can be considered heavy for a good bass tone. If it was double the weight, I would understand.

    I re-read the post and I too found it self-defeating to use the B4R as a power amp. Unless you can get the B4R for real cheap, I suggest going for a decent power amp and be done with it.

    Well compared to a 90 pound SVT you're right, but I switched from a B4r to a 6 1/2 pound Markbass LMII which is a 500 watt amp that sounded better than the B4r and was 2/3 the price!

    45lbs to 5 lbs and the tone is better? Nice! I didn't mean any offense towards to you in particular. I just can't stand it when people get rid of an amp with the tone they love for something lighter that does not sound as good (and they know it).

    I wish I was a Markbass fan, I could save myself a lot of lugging! My 40 or so pound Mesa 400+ is not too bad though.....
