True Speaker emulated output for huge tone without a speaker cabinet





ISP Technologies calls the Theta Pro 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 on stage during gigs, you'll appreciate the flexibility of the Theta Pro DSP preamp pedal.





Ultra-quiet operation with Decimator noise reduction built in





You won't struggle with buzz and hum with the Theta Pro DSP in your guitar rig. It has ISP Technologies' acclaimed Decimator noise reduction technology built right in, and it's ready to cut out noise without affecting your tone or playing dynamics. Even if your tone relies on ultra-high gain settings, your rig will be whisper quiet when you're not playing.
