15W Tube Guitar Head with Switchable Output to 7W, and 3-band EQ. An all-tube, 15-watt guitar head, the OR15H features four stages of gain which offers huge tonal range. A powerful 3-band EQ lets you dial in the exact tone you want and need. The OR15H switches from 15 to 7 watts for studio use and recording. The Orange OR15H puts a lot of high-priced, boutique amps to shame with its clean crunch to full on overdrive sounds. At mid gain settings this tube head has tons of vintage British character.
