Slightly used - Drawing from Yamaha's popular THR series amps comes the THR100H Dual guitar amplifier modeling head. The THR100H Dual has two independent amplifiers in a single head. You can play them separately or both at the same time; it's like playing two amps at once. You can customize each amp by choosing from five classic amp models and five power tube models. You can further tailor your amp's feel and response by choosing between Class A or AB circuit design and changing the speaker response by uploading Impulse Response files to the amp. The variable output (25W/50W/100W) and XLR line-outs make the THR100H Dual ideal for stage, rehearsal, or studio. The Yamaha THR100H Dual guitar amplifier head delivers classic amp tone and feel in a portable and versatile package.
