"Superb example of the Neuron, one of the absolute pinnacles of Axel Hartmann's original sound engine concepts and design flair. There is really nothing anywhere near like this in the synth world. You could argue that it is really just a couple of 90s computers inside a box - but then you listen to the sounds that flow out of it, and use the pretty much unbeatable control surface, and you have to acknowledge it as a masterpiece.
Many of these machines packed up over the years, but that was more often than not down to a hard drive failure. That has been solved on this machine by replacement with a modern SATA solid state drive. It's in beautiful cosmetic condition as well as full working order, and comes with its manual, a UK IEC lead, and actually the old hard disk in case that has uses in future.
This is not the easiest synth to pack safely (overhanging keys and those potentially damaged little mushroom controllers) - but we will make an excellent custom carton: 30GBP."

"Newly restored Roland CR-5000
Knobs have been cleaner though and the case has been cleaned and refinished to get rid of yellowing. The original switches have been replaced with linear & silent keyboard switches and 3D printed keycaps.
The new switches are awesome and will easily last 40 more years. The case is missing some screws but is sturdy. The case has a stain shown on the right side of the drum machine. Everything works on this drum machine and it’s ready for a new home. Thanks!"
