The Theta X DSP makes a powerful centerpiece for your guitar rig. It includes both Vintage and Theta preamps with control over sag and pre- and post-distortion EQ for impressive sonic range — from rich and clean to brutal high-gain, this preamp has you covered. You get an array of great-sounding effects with individual control over each. Build exciting effects chains with a wah, envelope follower, compressor, phaser, flanger, chorus, pitch shift, rotary speaker, 1,300ms delay, and reverb. Save up to 224 of your custom presets for instant recall. We appreciate the fact that you can plug into your power amplifier, send a speaker emulated output direct to the sound system or recording device, or even both simultaneously.

ISP Technologies calls the Theta X DSP’s speaker-emulated technology “True Speaker” convolution, because you have practically as much control over your tone as if you were miking a real guitar amplifier’s speaker. It emulates vintage speaker models with amazing results, and you can alter the sound by repositioning the virtual microphone. Whether you want to record in your studio without a loud speaker cabinet, or want to reduce volume onstage during gigs, you’ll appreciate the flexibility of the Theta X DSP.
