JazzNote Posted December 3, 2015 Share Posted December 3, 2015 I'm wondering what the resistance of the volume pot in my 1998 LeGrand is. Unfortunately i cannot read it as the soldered wires cover a good portion of the pot. TIA JN Link to comment Share on other sites More sharing options...
sparquelito Posted December 3, 2015 Share Posted December 3, 2015 From everything I have read, Gibson uses 500 ohm pots for arch-tops and semi-hollow body guitars equipped with humbuckers, and either 250 or 300 ohm pots for mini-humbuckers like the Legrand features. (And usually 250 ohms for single coil pickups.) If you were to wire in a 500 ohm volume pot, you may find a brighter tone than the Legrand currently produces. If I am wrong here, I will humbly demur. I always appreciate enlightenment, and the opportunity to broaden my knowledge base. :) Link to comment Share on other sites More sharing options...

Common Hi-Z magnetic pickups have impedance peaks of several hundreds kOhms to several MOhms, and along with a guitar cable still some dozens of kOhms. Some hundred Ohms would practically short them out. Link to comment Share on other sites More sharing options...
JazzNote Posted December 3, 2015 Author Share Posted December 3, 2015 If you were to wire in a 500 ohm volume pot, you may find a brighter tone than the Legrand currently produces. - quite the opposite, after replacing the pickup some years ago i still find the highs in some playing situations a bit unpleasant and had in mind to try a lower resistance for a natural reduction of brightness.

Measure across the two outside lugs. Link to comment Share on other sites More sharing options...

Rather than replace a 500k pot for a 300k, you could simply turn the volume down to produce the same thing. Also, the tone control could be used.

sparquelito Posted December 3, 2015 Share Posted December 3, 2015 Thanks for the elucidation. I did some research early this morning, and saw the 'k' after the numbers, 500, 300, 250, etc, and figured it was some keyboard-easy shorthand for the usual 'ohm' symbol. So that's kilo-ohms. Got it. Much appreciated. Link to comment Share on other sites More sharing options...

Thanks! there are situations when i just have to turn the volume up. as for a tone control, i'm experimenting (again) with the most suitable cap value. i also ordered a handmade Kent Armstrong pickup, hopefully this will help solving my problem.
