I have a Gibson LP Custom from 1980, my first 'real' guitar. Played many gigs with it, but the last 15 years I preferred my strats.
When playing primary on strat, a LP can by rather dull, and for guitar changes I do not want to change the eq settings on my amp.
This bridge adds a little sparkle to the tone. Still I look for extra updates on my LP, but this was a nice step in that process.
