Since my band plays music from the 60's, I wanted a powerful, yet somewhat portable bass amp that I could take with me to gigs that had the look of a late 60's Vox, but with the use of modern features and technology. So, I took an old empty Vox Buckingham head box that I've had for years and installed a Gallien Krueger RB1001RB-II in it.

For the cabinet, I purchased a Vox V212BN cab with the trolley from Northcoast Music. The cab comes as an open back and brown grill cloth, so i made a new sealed back for it as well as a new speaker baffle board and regrilled it with black Vox grill cloth. I cut two 3" ports (with 4" long tubes) in the baffle and made them so that they allow me the option of having a ported cab or capping off the ports to make it completely sealed.

For the speakers, I installed two new Eminence 2512 Neo's that handle 250 watts each, so the cab can handle 500 watts. Since I didn't want to use a horn and x-over, to give the speakers just a little more high end, I cut off the paper dust caps and installed a couple of aluminum JBL domes.

Although this rig is pretty small (and the cab is now very light), it is super loud, full sounding and can easily handle all but the largest of rooms that we play in without PA support.... i think that it looks pretty cool to have an amp that "appears" to be from the era of the music that we play, but far surpasses the original in both tone and output and i couldn't be happier with the way that it turned out.

when I want the same look but I'm in a little bigger room and want the sound of a tube head, i use this one. (although i need a truck to haul this one). I built the head myself using a blend of a Fender preamp (with a few enhancements like a deep switch and a two position mid cut switch) and a slightly higher powered Marshall power amp. it puts out about 160 watts RMS. The cabinet has two JBL K140's in it.

The tube head isn't quite as loud as the GK but it is still very powerful, and it has a different response, tube compression and punch than the GK head.

thanks! you should've seen the look on the faces of some of the bass players in the audience at some of my gigs when i've used the small one. they kept insisting that i must be also running a direct line into the PA. i had to actually prove it to one guy that i wasn't by showing him ("nothing up my sleeve" as they say)
 
Wow... I just went to your website and read your bio. You are now THE MAN! I really enjoyed the stories of growing you up in LA and the music scene as you experienced it. I live in LA and have run into a few 'old timers" and always dig hearing their version. If you ever get a hankerin' to plug into one of the old Acoustic amps again, gimme a shout.. I got a bunch of em'!
