Stryper Tone in a Box — And So Much More

Michael Sweet of Stryper has inspired fans the world over with his holy hair-metal tones: his tight, controlled chug; his smooth, sailing leads; and his tasteful bouquet of stereo effects. Now you can cop Michael's exact sound with the ISP Technologies Michael Sweet Theta Pro DSP guitar preamp/pedal. When we say exact, we mean it — this is the very same box Michael uses out on the road with Stryper. It ships with 11 of his personal presets and includes several enhancements over the original Theta Pro DSP. These include a 3-band parametric EQ, post-distortion bass and treble to smooth and sculpt dirt, a tuner, and a totally realistic rotary speaker effect. The ISP Michael Sweet Theta Pro DSP comes in a righteous Stryper-black-and-yellow chassis with Michael's silkscreened signature.

How does it stack up to the Theta Pro DSP?

Beyond Michael's enhancements, this is the same ISP Technologies Theta Pro DSP — the floor-controlled guitar system with the vintage preamp, bounteous gain, and complete suite of studio-quality 32-bit effects — that has had the guitar industry all hot and bothered the past year. 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. There's even a tuner (accurate to a 1/2 cent) onboard. It's literally all you need to achieve the tones your live shows demand. Run the ISP Michael Sweet Theta Pro DSP into an amp stack for the genuine article, or direct out into a PA via the speaker-emulated out for portable performance done right.

Your one-stop tone shop for electric guitar

From rich cleans to the highest gains, the Michael Sweet Theta Pro DSP has you covered. You get a range of great-sounding effects with individual control over each via the smart switching system. Save up to 256 of your custom presets for instant recall, or choose from Michael's included Stryper tones for instant inspiration. And Sweetwater guitarists 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.

Huge tone without the speaker cab

ISP Technologies calls the Michael Sweet 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 Michael Sweet Theta Pro DSP preamp pedal.

Ultra-quiet Decimator noise reduction

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

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Best Pedal

I have owned a lot of pedals through the past 40 years and I have yet to own one that has so many sounds. 223 pre-sets to include the Stryper sounds. They will raise the price and they need to. Way more then it should be.

Get it while the price is low.

Incredible sound! Top notch costumer service!

This processor has everything you need and sounds incredible! Customer service is also to notch! I'm not very tech savvy and had some questions about set up and called ISP. Buck Waller explained the unit with great detail and answered all my questions. If you're on the fence on buying this I would not hesitate! The noise desimator on this unit is the best I've ever heard along with the Effects and multiple amp and speakers selection sounds make this the most versatile piece of equipment I own!

Incredible sound and response

This pedal delivers everything they advertise and more. The preset sounds are amazing and the product is very easy to operate. If you are looking for an "All-in-One" pedal that is easy to use, has great responsive sound, is light weight and gives you unlimited options, then do yourself a favor and check this pedal out. That is the only way you can truly appreciate how great this is.
