The discontinued Tech 21 Sansamp Tri-AC. 100% analog tone with built-in mic'd cabinet simulation. Has 3 modes: tweed (Fender clean), brit (Marshal crunch), cali (Mesa crunch). Stupid easy programming--just fiddle the channel switch and knobs and double-tap one of the footswitches. Each knob has an LED that's solid at the saved setting and flashes slower as you deviate from the saved setting. So no matter where the knobs happen to be, you can always find the original setting for any saved tone. Pretty damn clever. Settings are saved even when it's not powered. Features a Putnam Guitars sansamp blend knob (extra $60), which allows you to go from completely raw to 100% built-in cab sim and everything in between. For recording, this means you can use impulses. And live, it can be paired with other cab sims, including impulse loaders like Two-Notes CAB or Digitech GSP1101. Standard 9V power jack; also has a convenient battery door on the bottom. Excellent condition. Just a tiny bit of finish wear on the edges. Velcro on the back comes off cleanly. $125 shipped in the US. A bit more abroad. Check, MO or Paypal.
