Hi Sgt Pepper, thanx for your reply. I wrote to Gibson and you're right, this is their answer: "
Hi Mr Gaspari,
The serial number refers in our database to a guitar Gibson ES- 335 Studio in Ebony finish, chrome hardware, made in 1988 ( 214th day ) in Nashville US. Unfortunately, we don't have available papers from 1988.
Features:
ES335 Studio: No f-holes, 2 dirty fingers humbucking pickups with covers (earliest with exposed coil PAF humbuckers), single bound top and back, mahogany neck, unbound rosewood fingerboard (earliest with ebony), dot inlay, no peghead ornament, decal logo, ebony or cherry finish. Introduced 1986.
Best regards,
".
I've got 2 more questions:
1. The man of the guitar shop close to me (Gibson reseller certified) suggests me to mount 498's (and not dirty fingers); do you know them? Are they similar to 490's? And what about '57 classic?
2. Gibson also told me that they haven't the coverplate for the back of my guitar; do you know where I can find it out?
I thank all for your help.
Nicola
