hi, if im not mistaken, there are currently 3 kinds of lp silverbursts in production now
1. epiphone silverburst
2. gibson lp classic custom silverburst
3.gibson custom silverburst
im not sure about no.1 but no2. is limited to a run of 400 in the guitar of the week series, and number 3 has the same specs as the lp custom made in the custom shop except it is in a silverburst finish
from a cosmetic viewpoint alone, no.1 looks more similar than no.2 to no.3 which is what i have
if you take the time to examine no.2 and 3, there are quite a few obvious cosmetic differences
hope i helped!
