Tech 21 Trademark 10 Guitar Amplifier Amp New with price tag, box, manual & dust cover. Selling AS IS because I know nothing about music or amps but purchased this at an estate sale. They told me it has never been used. I plugged it in and it lights up but I was unable to test with a guitar because I don’t own one and wouldn’t know musically what to look for. I will accept a return and reimburse your item price but I will NOT reimburse your shipping costs. From another exact listing: We call this our Direct Recording Combo Amp. We should have called it Yoda, because there isn't much this diminutive wizard can't handle. The heart of the crafty Trademark 10 is a modified version of the super flexible SansAmp GT2 pedal design. Construct your tone by selecting amp character, gain structure and speaker type, and then use the drive controls and active three-band EQ to nail your sound. The 10-watt output is plenty loud for practice and monitoring but the balanced XLR and 1/4" outputs bring the big tones of this little combo to the studio mixer or PA system. Bedroom, rehearsal, studio or club, the Trademark 10 will prove it's a giant amongst compact combos.
