This Yamaha THR10C amp has apparently been discontinued, so here is your chance of picking one up at a reasonable price! I have only used it a couple of times since new. Amazing sound from such a small unit! Also have a carry/accessory bag for it. Here are the specs from the Yamaha website: High-End, Hand-Wired Tone At Your Fingertips. THR10C takes the personal-amp concept to a new level of audio fidelity. The finest tube amps respond to a player's every touch - with picking dynamics and playing style adding as much to the tone as your guitar and pickups. Using Yamaha's exclusive VCM (Virtual Circuitry Modelling) technology, THR10C perfectly recreates the unmistakable response and dynamics that only a boutique tube combo can provide.
