Re: Gibson Sonex?
Not exactly Gibson's finest moment,Im afraid.
They usually weigh a ton and huge gaps and movement in the neck pocket.
The body was a resin composite called "Resinwood" or some such crap. Basically MDF.
They had Velvet Bricks or Dirty Fingers,but no matter what you put in,the construction just killed tone.
Only buy it if it's dirt cheap and you want to do some experimenting.
