I'm not familiar with the G&L, but did it on my Jackson with Floyd Rose. Fairly simple process. I cut two small slats from some extra hardwood flooring and epoxyed them together as my block (about 1/2" thick). Remove the center spring so that you have clear access to the trem and guitar body, depress the trem forward and epoxy the block in place between trem and body.
For me it helps keep the guitar in tune better and is better for intonation. I can still use the trem for dives, etc... but can't pull up on it- which I never did anyway. Doing this took a rather finicky guitar and made it much more reliable. I'd do it again if I ever get another trem.
I've done it to my Legacy two different ways...both seem to work fine:
(1) Two blocks of wood cut so that they fit snugly, one on each side
of the trem block. (I used oak...dense wood to better transfer the
vibrational energy.) I then drilled a 1/4" hole in the narrow edge
of the bridge side block and split the block length wise, about 1/2 way
down the length of the block. I inserted a small, plastic expandable
hollow wall anchor into the hole (like you use to hang a picture on
drywall) so that when the little insert screw was tightened, it spread
the "leaves" of the cut block to make a tight fit when the wood blocks
were inserted around the trem block. This has two advantages: It
maximizes the transfer of vibrational energy from the trem to the
strat body, and it makes removing the block really easy for setup
(2) Cut a single block that fits snugly on the neck side of the trem block.
I put double-sided tape on one side of the block. Then put in three
Both seem to work fine and both improve the tuning stability. I thought I
got better tone from the first method...but it is subjective and subtle,
if true. (Basicly, the same argument as for using a Callaham replacement
No...sorry...I actually tried the two ways in that order (so #2 is in the
Legacy now...else, I'd snap some pics for you). I changed out the block
when I changed the pickups to Fralin Blues Specials and sent the guitar
to Phil Jacoby at Philtones to have the neck Plek'ed. Once it was all
setup again, I reblocked the trem using the second approach.
Both ways were pretty easy...it took me an hour, perhaps, to cut the
wood blocks. My description was pretty poor....if my paragraph is
unclear (probably is), I could email you a quick sketch, if it would help.
Anyway...good luck. I thought blocking the trem was worthwhile.
Someday I'll do the obvious thing and simply get a hardtail strat....
Cool, yeah Phil's great. Talked with him on a couple of occasions. So your G&L is pre-Plek. How are you liking the Fralin Blues? Have the baseplate on the bridge?
Yeah, ~2002 Legacy. Got it from a TGP'er about 2 years ago. Swapped the stock tuning machines for Schaller locking, the stock pups with Fralin Blues Sp (with baseplate), and Phil Plek'ed the neck, cut a bone nut and dressed the frets. Transparent finish on swamp ash, maple neck and board. Sweet strat. And I agree...Phil is A++ in my book.
The Fralins were a BIG improvement (IMHO) over the stock pickups. My problem is that I'm just playing it less...my musical interests are changing and the strat just doesn't get the play time. Ah, well...part of GASS, I guess, eh?
