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!

Easy installation of Hammond CU-1 Tremelo/Chorale Switch

This accessory was amazingly easy to install on the Hammond XK3 keyboard. Having owned B-3 with tremolo/chorale switches, I can assure buyers that the CU-1 works exactly the same as it does on the tone wheel organs. I'm impressed that it controls the Leslie 3300 as well as the internal Leslie simulator in the XK3 perfectly.

Educator/Pro/Keyboard Player

This unit does exactly what I need it to do. I have the XK3C Pro System and the Neo Ventilator for the organ. The CU-1 Tremolo/ Switch
is attached to the lower manual and was very easy to install. I can
change from fast to slow or off very easily. I leave it attached most of
the time when I go to gigs. Oh by the way, it plugs directly into the remote jack of the NEO Ventilator.

Tremolo/chorale Switch

I just received my Leslie switch yesterday. I was amazed in how fast it came. I was expected a 3-5 day delivery when in fact in showed up in only two. The Leslie switch was easy to install and I have no issue with it. I'm also glad to know that it comes supported with a 2 year warranty in case something should go wrong. Thanks Sweetwater.

CU-1 Excellent

I have used the CU-1 with my Hammond for a long time and am very happy with it. Getting it to work is a breeze with just a quick change in the system menu. It works flawlessly. Take a deep breath though, before you look at the price!

Excellent!

This 'half moon' style Leslie switch works wonderfully with my SKX Pro and Studio 12. In a way it's a luxury item but for me well worth it to get as close as possible in every way to the experience of playing a vintage Hammond thru a vintage Leslie! In practical terms, when I do play the vintage rig at music festivals and in the studio I don't have to consciously think about where's the Leslie switch. But mainly for my own self-indulgent enjoyment of my own rig.
