Selling my SAMAMP bass tube preamp. These preamps are made right here in Birmingham Al by Sam Timberlake. He is well known for his boutique guitar amps and cabinets, but also makes a killer bass pre. You could say this amp sounds similar to a B-15,SVT, SVP Pro, another TB'r describes it as 'like an A-Designs REDDI w/ tone controls and more gain.' It can go anywhere from clean, to a lil dirty to full on distortion. I normally use this preamp with my TF750A, going straight into the poweramp, and have been very happy. Great for slap and fingerstyle. The samamp sounds great in the studio as well. The settings I normally use are shown in the pic, aside from the master level... For other descriptions of the Samamp, check here http://www.talkbass.com/forum/showthread.php?t=584976&highlight=samamp. http://www.talkbass.com/forum/showthread.php?t=623815&highlight=samamp All of Sam's designs share the same innards, but the chassis differ. Mine has been upgraded as well to the last and most current version Sam has said hes happy with his most current version, so no more upgrades. Mine is in a smaller box format (13in by 5.5 by 2.5), so its very easy to carry around. Features: 1 12ax7 and 1 12au7 preamp tubes -Gain, Bass, Mid, Treble, the treble on my pre has a pull detent to further shape that frequency band, unlike other SAMAMPS -2 separate outputs w/ volume control for each. -All point-to-point wiring and top spec parts, no circuit boards here!! Im looking for $400 shipped conus. Only reason Im selling is because im gassing for a few things at the moment, I know I can always grab another from Sam if needed! Amp is in great condition, it had a checkup with Sam about a month ago. Feel free to ask any questions! trades im looking for are UL210 S1, or Enigma Q-balls and BOSS RC2.
