Description

---|---|---
Classic| Clean| A low-gain preamp for sparkling American-style cleans, with 6L6 tubes in the output stage for brightness and a strong midrange.
Crunch| EL84 power tubes in a true Class-A configuration with a highly responsive EQ for rich, complex harmonic tones and warm overdrive. Inspired by British chime.
Lead| A low-gain preamp with an EL34-based power section that breaks into classic British over- drive as the master volume is pushed.
Hi Gain| Powerful modern distortion that fills out as the high-gain preamp is pushed. Tread carefully after 12 o’clock.
Special| 12AX7 and 6L6 tubes in pursuit of the “Brown” sound. Set the gain around 11 o’clock for classic rock crunch, or crank it for saturated rhythm tones.
Bass| Woody, vintage tone with late breakup.
Acoustic| Designed for acoustic-electric guitar, modeling the response of a boutique condenser microphone.
Flat| A neutral tone with no amp or speaker modeling. Great for connecting other instruments to your THR.
Boutique| Clean| A low-watt EL34 design. Turning up the preamp gain will thicken up the cleans, then push into bluesy overdrive.
Crunch| A deceptively simple amp circuit with just a single 12AX7 and EL84. A full, no-frills tone that is highly responsive to picking dynamics.
Lead| A version of the Classic/Lead circuit, modified for extra gain with a darker tone and scooped Mids.
Hi Gain| ECC83s into 6L6s for high gain with a highly responsive EQ, inspired by German engineer- ing.
Special| Four 12AX7 preamp tubes into 6L6 output tubes. Tight, fast tracking for crushing high- gain.
Bass| Full, modern tone that breaks into a fuzz-like overdrive when pushed hard.
Acoustic| Designed for acoustic-electric guitar, modeling the response of a boutique tube micro- phone.
Flat| A neutral tone with no amp or speaker modeling, and a slight bass boost. Great for con- necting other instruments to your THR.
Modern| Clean| A boutique, low-watt EL84 design that adds fullness and sustain as the master volume is turned up. A great match for neck pickups.
Crunch| A mid-volume boutique design with 6550 power tubes. Listen for tight bass response and a singing sustain.
Lead| A high-gain design with 12AX7s into EL34s, for the tone that defined 1980s hard rock and heavy metal.
Hi Gain| A boosted version of the Classic/Special amp, with even more gain for aggressive rhythms or searing leads.
Special| A classic overdrive circuit before the preamp tightens low- frequency response and provides even more gain. Ideal for extended-range guitars.
Bass| Vintage voicing with early breakup for overdrive that works well with bass or guitar.
Acoustic| Designed for acoustic-electric guitar, modeling the response of a boutique dynamic micro- phone.
Flat| A neutral tone with no amp or speaker modeling, and a slight mid scoop. Great for con- necting other instruments to your THR.
