I have a Jamhub. Seemed like a good idea at the time, and still does, but I have never used it.
Also, I have a Zoom B3n which I have never gigged and only used at one practice, and a Line 6 Helix LT that I have powered up 5 times, once to take pictures of to sell.
Probably if I looked in the cupboard there is more than I could ever care to mention!
