Preamp, Effects, and Impressive Versatility

More than a guitar preamp, effects processor and floor controller, the ISP Technologies Theta Pro DSP pedal is ready to be the heart of your guitar rig. It's a fully-programmable digital version of ISP's acclaimed Theta Preamp, and it can serve up ultra-high-gain tone with no aliasing. Create your own custom effects chain, then simultaneously drive your amplifier rig while sending speaker-emulated outputs direct to the PA system. Guitarists and engineers at Sweetwater are impressed with the versatility of the ISP Technologies Theta Pro DSP pedal, and we're sure you'll find it more than capable both on stage and in the studio.

Your one-stop tone shop for electric guitar

In all, the ISP Technologies Theta Pro DSP pedal can serve several duties in your guitar rig. It's a tone-packed preamplifier with impressive sonic range - from rich and clean to the highest-gain tone, this preamp has you covered. You get a range of great-sounding effects, with individual control over each from the smart switching layout. Build exciting effects chains with a wah, compressor, multistage stereo phaser, stereo flanger, tremolo, four-voice chorus, pitch shifter, stereo rotary speaker, 1,300 millisecond delay, stereo ping-pong delay, and reverb. Save up to 256 of your custom presets for instant recall. When you're ready to rock you can plug into your power amplifier, send a speaker emulated output direct to the sound system or recording device, or even both simultaneously. There's even a tuner (accurate to a 1/2 cent) onboard!

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.

Greatest ever....a must try
5/5

Quality Tone

I have used guitar effects processors for 15 years stereo direct through the mixer. This guitar effects processor is supreme to any that I have owned. It allows pre & post eq to fine tune your tone. The built in decimator technology is awesome - noiseless tone. Has all the effects needed and makes your sound soar. I can achieve any tone I desire for electric and acoustic (with a piezo pickup). My setup: Parker fly deluxe guitar, 2 mission eng'g kemper model expression pedals, 1 for volume & 1 for expression, stereo xlr direct into a hi end mixer and front show system and it gives me a big sound. Also, a TC mini poly tune2 mini tuner with true by-pass.

Theta ROCKS again!!!!

I demoed the snot out of this thing at NAMM. Everything it's cracked up to be. Sonically, it's just amazing. And at NAMM, it was just a prototype!!! The Theta preamp is just like the analog versions you find in the head, combo, rack and floor pedal Theta. The four-voice chorus is rich, smooth, clear and incredible. Delay and reverbs that are lush and open. Tremelo, phaser (is excellent) and a great flange. An expression pedal out that can control any parameter you assign it to... two XLR outs with KILLER cabinet emulators and simultaneous 1/4 inch stage outs with their own separate volume so you don't have to fight the sound guy. A Vintage preamp for blues, jazz, rock and mid gain tones that is dynamic and response to pick attack and rolling off/on the volume knob on your guitar. A Jump feature to jump from one preset to another without scrolling... many other killer features... but most importantly ALL OF IT SOUNDS AMAZING. Decimator built in to kill any noise. Simply incredible...
