I normally play my guitar and bass with volume at full but the other night I backed off a bit and noticed My SG Standard got darker. I went to check my other SG that did not darken as much and upon opening the control cavity found I have put a treble bleed (high pass) circuit on each volume pot a couple years ago. Getting to almost 68 my memory is not what it used to be. So I guess I will be putting those on my newly acquired SG Standard. Also, was getting hum that went away when I touched strings, bridge etc. so I took the control plate off, lined it with copper shield and grounded via a strip of copper shield on the inside wall of the cavity and soldered a ground to that strip. Problem solved. Glad because I did not feel like fully lining the cavities on this one.

LTB, on a Gibson you can simply rewire the tone pot and solder the tone cap directly to the volume control (no need to add another cap). This preserves more of the highs as you turn down from 10. Popularly known as 'Gibson 50s wiring' because this is how Gibson wired their Les Pauls and 335s in the 1950s. This scheme is a bit more subtle than adding a treble bypass cap.  |

Very interesting Peegoo! More easily done on earlier models than the newer that have circuit boards ( but still can be done) |

I’ve always found the ‘50s wiring preferable to a treble bleed mod.
IMO, YMMV, void where prohibited.

You can also do this mod to any other electric guitar with a passive circuit like a Strat or Tele. It's just a matter of rewiring the link between volume and tone pots.

Love the treble bleed. All my electrics have them. But you have to make sure you have the correct values. It depends on the value of your pot. If the value of the circuit is too high, it can sound harsh; too low, you can lose high end.
Along those lines, you know what I really really love? The bass contour on Reverend guitars. It's basically an adjustable high-pass filter, and it makes the guitar so versatile. I don't understand why more guitar makers don't install them.

I used the Stewmac treble bleed however I made mine for about 50cents each verses their $6-$9 each and works really well Stewmac's Treble Bleed Video |

Peegoo, in next week I am going to give your suggestion here a try and see how I like it. Update: I replaced the circuit board (due to inadvertently damaging the Bridge Pickups Volume pot). While looking for 500K pots and caps to replace the board I found an Emerson Custom SG prewired circuit that was beautifully done. They used a .022uf cap for the Bridge Tone Pot and a .015uf cap in the Neck pickup's tone circuit. I have a Neck pickup with Alnico 3 magnet and a 498T Alnico 5 Bridge (stock). The Alnico 3 pickup was a little dark with stock circuit. With the 50's wired Emerson circuit's .015uf cap the Neck pickup is brighter and clearer. I considered using a .022uf cap for the neck but found I could still get much of the previous circuits tone on the neck pickup by rolling off the tone pot a little. Also where I had to install copper shield on the back side of the control cavity cover and ground it (using a narrow strip of copper shielding to contact the cover shielding) due to noise there is no noise now even with the cover off the guitar. I am happy so far. I may consider a Rumplestiltskin Humbucker in future but I would then need to get both Neck and Bridge pickups as the Nickel would look a little weird against the chrome 498T. For $300 for both together I will have to do a lot of thinking "do I really want to do this" and "will it be worth that price. I am also considering Fralin PAF's |
