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!

Perfect and Affordable

I'm lighting a simple one act play with only five light cues using 18 Slimpar Pro instruments, and Lightkey on a Mac. The price was right and opening night was perfect.

Rated 5/5

Great interface

This was worked flawlessly connecting my PC to my SlimPARs. If your DMX device is 3 pin just know you need the inexpensive 3 pin to 5 pin cable that Sweetwater also sells. Everything is working well with my Q Ltght Controller software.
