Here's a one-of-a-kind Metasonix system (D-1000, D-2000 & Delptronics Trigger Man). There are built-in speakers, so you can just plug the A.C. cord into the wall and get to work.

Eric is including a signed Certificate of Authenticity which says:
"This is to certify that the red suitcase demo system, presently containing a D-2000 and D-1000 mounted in a custom rackmount panel, was constructed by myself in 2013 for its original use at trade shows and private demo events. The first version contained this D-2000 plus an S-2000. It also contains a pair of small speakers and a 12v dc power supply."

There you go. You want something rare? Well, this is IT!
