i've got a mid 70's goldtop deluxe that is pretty dark- not due to pickups, it's dark unplugged. any suggestions on a different bridge i could try that would bring out some of the higher frequencies and "ring"? the guitar needs more clarity in the low end. it's probably just the wood, but it has such a nice feel, i want to try to save it. thanks for your help,

One thing you can try that won't cost you anything is to tighten the tailpiece down against the body and top wrap the strings (feed the strings in from the neck side of the tailpiece and wrap them over the tailpiece). I have done that with all my Gibsons and it makes a real difference. Another option is to just try some different brands of strings. And finally if you want to try replacing the bridge and tailpiece, I'd suggest trying the Tone Pros. Hope that helps.

i checked out the pots and found this info. when off, the vol. pots read .108 and .140 ohms (neck/bridge). the tone pots read .042 and .051.
vol. pots have code 1377902 70-034 while the tone pots have code 1377822 71-079
my other lp deluxe -1976- which really really sings has pots that read:
vol. both read .036 ohms
tone both rad .022 ohms
and all 4 have the code 1377605 70-034


maybe i have some funky pots? if the imp. is higher, could it be choking the top end?
thanks for the help,
david

Your numbers don't really make any sense (it's hard to measure the pots in-circuit), but yes, the pots can make a big difference. You might want to consider an RS kit from RS Guitar Works (I think that's the right name). The volume pots should be 500k+. Sorry I didn't think to mention this before.

All seems like good advice from Bill, to me.

Modifying tonalities on guitars can be a real can of worms as there are so many variables with some elements being difficult (if not impossible to change- like woods and such).

I am currently working on Derek Trucks backup SG trying to get it in the ballpark tonally with his main show SG. I've gotten the action close (that's the easy part actually Wink ), removed the vibrato mechanism, installed a stop bar tailpeice, and am now working on the electronics as everything else about the two guitars is now very similar.

They play similar now, but still sound radically different.

Daved:

It still blows me away that you are working with both Robben and now Derek Trucks. I've known Robben for 22 years, but I just recently (in the last 2-3 years) became hip to Derek. I just love his playing, feel and sound. I think I've seen him perform live 5 times in the last 2 years. He also seems like a good guy. I got the chance to meet him last year.

His wife Susan Tedeschi also kills me--what a voice!! I can only imagine what kind of talent their kids are going to have.

thanks for the tips. i went to the rs website and will order the electronics upgrade as well as a push/pull pot to add coil split. i may be wasting time, because i know the wood is the main cause of the dark sound (it lacks top end when unplugged) but anything i can do to clear it up is worth it- the guitar plays incredibly. 2 questions:
do the cap upgrades make that much of a difference compared to the cheap ones in my 79 deluxe?
shouldn't all 4 pots have the same ID code? i think the tones might be linear, because they don't really brighten until you're halfway thru the travel, until my other deluxe which gets much brighter when the tone goes past 2 (like the volumes). any, thanks very much for your help-

Titanium bridge saddles would help brighten the tone as would stainless steel frets.

the RS electronics upgrade made a huge difference - thanks for the tip.
the pots inside were actually 300K for the vol. and 100k for the tones!
the guitar is much brighter now ,( but sadly a bit louder in output- i liked the way the lower output hit my fulldrive pedal). just takes getting used to working the volumes differently.
the guitar still doesn't have that open top-end, but that's clearly the wood. it's really full-bodied now with the new electronics, though.
thanks for the great tip. the guys at RS were very helpful- and they've got a mod for the neck vol. pot that keeps it from getting muddy when you turn down. a cap. with 2 resistors. works great.

Which RS kit did you get? I'm thinking of doing a similar upgrade on my LP but was kind of overwhelmed by the choices on the RS website.

Cheers

Try lowering the pickups a bit. You should fine a sweet spot where they sound the best. That should lower the output a little for you.

If you have the pickups very high, that will tend to make a muddier sound. Lowering them a bit will open up the top end as well.

There are basically two kits, one with long shaft pots and one with short shaft pots. If you have a LP with the metal plate inside, you need the long shafts. If you have a Historic, or 335, then you need the short shafts.

There are also two "grades" of kits, normal and premium. For the normal kits they just toss in 4 pots and some caps. For the premium kit, they measure all the pots and make sure that the volume pots are 500k+, and include Hovland caps. I recommend the premium kit, although I ended up not using the Hovland caps as I found some caps made here that I like better.

Thanks very much, Bill. That's cleared it up. What kind of caps did you find here?

They are Japanese made Vitamin Q's. About 300 or 400 yen in Akihabara.
