Hello out there---I just bought a Grammer G-10 which I believe is all solid spruce/rosewood. It has an "a" under the logo which I am told means it was built when the company was under Ampeg ownership.
The serial #2118. George Gruhn told me it is likely late 60's, as he attended the bankrupcy auction in 1971.

The tone stands well apart, Can anyone tell me a bit about this guitar, i.e., confirm solid, year made. Worth $1400 I paid?
