Theta Pro DSP by ISP Technologies

The Theta Pro DSP by ISP Technologies is a floor-controlled guitar processing system with fully programmable THETA preamp and Vintage Preamp. It features 32-bit floating-point processing with state-of-the-art A/D and D/A converters, providing 124dB dynamic range between input and output and over 1500dB internal dynamic range. The pedal incorporates a proprietary hyper-oversampled distortion algorithm that delivers higher gain than any other digital preamp with zero aliasing or digital artifacts.

Key features include TRUE SPEAKER, which offers ISP’s convolved Speaker Samples for true “direct to mixer” live or recording realism, and a patented Digital Decimator for real-time guitar noise reduction. The pedal also includes pre-distort and post-distort tone shaping with multiple band full parametric equalization, as well as studio-quality effects processing with wah, compressor, multistage phaser, stereo flanger, four-voice chorus, 1300ms delay, and studio reverb.
