Hi kids... Help I have a late model Epi 335 pro w/ coil tap. My buddy has an Epi 339 w/ coil tap as well and we think the lack of tone control is less than wonderful. My older guitars all have typical tone IE back it off and lose volume (and the treble is GONE) but I'm used to it and I like it that way.... Yeah, the tone doesn't cut off 'till you're right at the end of the control sweep and even then it only reduces the treble a little... My bud already switched to Seymour Duncan P-90 Fat Cats w/new 500k pots. He's happy and the 339 is okay. But I like my humbuckers so I'm ready to fish out the 335's guts thru the f holes (always fun) and thought it wise to consult y'all. I believe Gibson has been factory including treble-bleed on some models... Is Epi doing that as well? Anyway, thanx in advance. You guys are always so technically brilliant ...I dunno why I didn't post sooner. cheers
Sorry, popsaka, but I had to move this thread, as it didn't belong in "John's Tones".
I dunno whether Epi is including treble bleeds or not. My Epi LPJ didn't have one, but it was a real cheapie.
If you plan to add a treble bleed, you should consult JohnH's thread on treble bleeds for appropriate values. Also, for what you currently have in the guitar, do you know what the pot value and taper are?
Thanx Newey... Sorry 'bout that... They're tiny little 500k's I dunno how to test for taper (w/ digital mm?) The pups are 7.96k and 8.45k The vol pots have the coil tap switch attached...
Oh well (sigh) I wuz hopin' for some inspiration before I just amateurishly attempted to get a more normal tone control in me Epi 335... I just can't figure why the tone control only affects the sound a tiny bit and only in the last 10 or 15% of the sweep... Perhaps Epi techs were trying to minimize the volume reduction effect? Thanx in advance and cheers
BTW the knobs are on so tight I'm afraid I'll damage something (I bought it new and its really quite luvly and plays like a mf riot)

StewMac sells a knob puller, admittedly it's hard to justify buying a special tool for a one-time use, but that would be the solution.
You can use a multimeter to test for pot taper, but it may mean disconnecting the pot to do so. Likewise, your readings on the pups won't be correct if the pups are connected to the pots when you measure them. But accurate values can be obtained without disconnecting, you just have to do some math with Ohm's law.
There is a thread entitled "discerning parallel resistances" by ChrisK that detials this method, I have to run to work so I can't link you to it at the moment, but it's in the Reference section.
