Suhr PT15 I.R. Pete Thorn Amp Head

The PT15 I.R. is the world’s first truly hybrid amplifier, marrying classic tube circuitry with a reactive load and digital impulse response technology.

With the PT15 I.R. we set out to combine the strengths of both analog and digital to create something new. The addition of a built-in Reactive Load and on-board impulse responses, make using a speaker cabinet optional for recording, or feeding front of house with a studio quality mic’ed up tone. Also included is a headphone output and auxiliary input to practice and jam along with your favorite tracks, wherever you are.

The all-tube three channel design offers a plethora of American and British tones, powered by a new 6V6 driven power section. The dynamics, overdrive, saturation and harmonics that we crave as tonal purists, is all here. By adding channel assignable IRs, you now have unprecedented versatility and control over your tone, expanding your choices more than ever before.

PT15 I.R. features channel-assignable impulse responses which are a breakthrough for live performance, letting you change the cabinet I.R. along with the channels of the amp. You can choose to play the amp silently on stage, or have a cabinet for stage volume while using the I.R. output to avoid the hassle, inconsistency, and bleed from mic’ing a cabinet. In the studio, you have the option of using the line output without an I.R. which gives you the flexibility to process impulse responses in your DAW.

Simply connect your headphones to the front of the amp, select an IR, and practice silently with no speaker cabinet required. Connect any stereo 1/8″ audio source to the AUX IN connection and you’ll hear the IR processed signal along with your backing tracks through the headphones.

Pre-loaded with authentic Suhr cabinets.

The PT15 I.R. comes loaded with 16 impulse responses of Suhr speaker cabinets. Six of the impulse responses are custom blends made by Pete Thorn himself. Because it is an open system, you can also load your own third-party IRs into the amplifier via USB.

Each of the three amp channels can be assigned its own unique impulse response. This means, for example, you could assign an open back 2×12 to your clean channel and two different closed-back 4x12s for your lead channels. It’s like bringing an arsenal of cabinets to the gig.
