After getting tired of lugging my Workingmans 12 into low volume gigs, I decided to look at getting a small, lightweight amp. Most of my gigs are piano/bass duos and often with an un-miked medium sized grand in an occasionally noisy dining room setting. Also, I didnt want to spend a lot of money. If I couldnt find a cheap one, I was going to continue using the SWR. Although the SWR is a nice, amp, I havent been able to get an uncolored sound from it. It tended to be a little muddy and undefined. I use a plywood bass (a Wilfer) with a Full Circle w/no preamp. I realize that a preamp could help and will probably pick one up at some point but I wanted to improve my portability first. I just wanted enough to give me a little boost in sound. I tried a number of the cheap 30 watt 1x10 combo units at the music stores using an electric they had on hand. However, they all flunked the first test farting on the open E. Then I tried the Behringer BX300. It had a very tight open E sound and was far louder than the other ones I tried. I decided to buy it and try it on that weekends gig with the assurance from the sales guy that I could bring it back if didnt like it with my upright. It cost $119 and weighed about 30 pounds (30 watt 1x10). I got it home and plugged it in and at first it sounded like s***. However, after engaging the shape filter and leaving its control knob at zero it sounded great. The sound of the amp actually seemed to melt away and it just seemed like my bass got a lot louder. At lower volumes, I had to get my ear close to the amp to determine just how much was my bass and how much of the sound was coming from the amp it was that colorless. I took it to the job and used it Fri and Sat nights. It sounded great on the job too. It was very clear and well defined. It had that woody sound I wanted to hear. Saturday night we had a pretty boisterous crowd (we dont get no respect) but it still cut through. I played with different piano men each night and they both thought it sounded good. I havent tried it with a drummer, but I have a feeling it might be able cut it. In any event, all I was looking for was a little boost in volume and it certainly gave me that. It wont add a rich bottom to your sound but thats not what I was looking for. I like the sound of my bass un-amped and wanted to get as close to it as I could without spending an arm and a leg (or even just an arm) One feature I suspect that helps is that fact that, like the other Behringers, it has a 1M ohm input. I havent tried a lot of different amps with my double bass but do have experience with my Workingmans 12 and a Clarus I used at a jam session. I couldnt get the sound I wanted with either. I know this sounds crazy it sounds crazy to me too. A $119 amplifier? Sounding good? Actually, to me it sounded great. Im expecting them to come and take me away any minute now.
