Rocktron PRO G.A.P. preamp $125
Solid state guitar preamp with flexible EQ and other goodies. Will do sparkling cleans and completely over the top shred sounds. Has HUSH circuitry built in, as well as two MIDI programmable 1/4" relay jacks for changing channels on an amp. Shows the wear you would expect on a 20+ year old piece of gear.
Mosvalve 962 Power amp $150
Solid state stereo power amp but these are also known for their "tube-like" goodness. 80W per channel at 4Ohms. Fan cooled, 8-inch depth. LOUD. Pots are a little scratchy when turned, this is common for these. Did I mention it's LOUD? Time to put that W/D/W rig you've been thinking about into action, or pair it with your modeler for a handy backup rig.
TC Electronic G-Minor MIDI controller $55
Compact MIDI controller similar to Tech 21 MIDI mouse. Will do patch up/down/select or can be programmed to send CC messages. When paired with certain TC rack gear (G-Major I, G-Major II, M300, M350, G-Force) can also control special functions like tap tempo and remote tuning. No power supply, but it will run on a standard Boss style 9V adapter.
Thanks for looking, and let me know if you have any questions!
