[Just pasting my post from Don's earlier thread..
It should have been in this one...]

A decade ago I bought a few Switch Vibracell solid body guitars...

Vibracell - a moulded plastic foam resin of some kind that was suposed to sound and play like premium 'tone woods'..

Vibracell didn't catch on with a conservative guitar market,
so I got them very cheap discontinued..

They were actually quite good, loads of sustain - but easily chipped...

Compressed paper Martins reminds of the vintage Danelectro guitars
made cheaply of minimal wood frame covered in hardboard...

They sounded great...
