The innovative HT-5RH head offers unbelievable tube sound in a compact format. Using the dual-triode 12BH7, wired in a push-pull circuit, produces the crunch and break-up characteristics of a traditional 100 Watt amp, delivering a sound rich in tube harmonics and compression even at the lowest volume levels. The Infinite Shape Feature (ISF) works with the three-band EQ to provide new tone-shaping control, along with the digital reverb. The emulated speaker/headphone output offers both 1 x 12" and 4 x 12" settings - great for recording or practice; a jam-along stereo MP3/line input is also provided.
