Randy Rhoads had a portable practice amp/effects board made for him by Zeus Audio Systems for traveling. The board consisted of a Boss DR-55 drum machine, Zeus 8401 Mini Amp, MXR Micro Chorus, MXR Time Delay and a MXR 6 Band EQ mounted in a Casio keyboard case.
Randy's original Zeus board came up for sale recently at auction and caused a lot of ruffled feathers and bad feelings. Most everyone agrees the original should have been returned to the Rhoads family following Randy's death. Unfortunately it was sold and is now owned by a private individual and has not made its way back to the Rhoads family yet.
I have made a replica of Randy's original Zeus practice board for my own collection and for all the fans to see. I have used all of the vintage correct effects and even found the same case used on Randy's. It was a fun project to do and the finished product is really cool, I still cant believe how cool this thing is.
