I've waited 18 years for the Kinman treble-bleed mod!

    OK, I've spent almost 18 years playing mainly Les Pauls or LP-style guitars.
    And the volume control has always bugged me.
    I didn't want to lose high-end when I rolled down the volume, so I just got used
    to making sure that the volume control was religiously turned to "10".
    In fact, I now realize that getting more treble out of LPs has been a life-long desire.

    On a guitar-less business trip, I passed time reading about treble-bleed mods on the web.
    The next day, I stumbled into a Radio-Shack buying 1000pf caps & 220K resistors.
    When I got back home, I forced myself to get out the screwdriver and soldering iron.

    I twisted and soldered the cap & resistor in series, then attached them to the volume pot lugs.
    (for both rhythm & treble pots)

    It was a mild PITA.
    And by PITA, I mean that I endured maybe 15-30 minutes of effort to cure an 18-year-old ailment.
    Jeez...

    OMG, the volume pot is now so much more useful!
    At "3", the guitar is clean... at "7", furry... at "10", Nigel! (but, one-less)

    So, I have a few questions:
    =====================
    Since I've always wanted more treble, should I try 1 Meg-Ohm pots?
    (I've never met a Les Paul that had too much treble)
    Then maybe I could actually make use of the treble-cut tone controls.
    Or...

    With the volume controls sorted, the tone controls need fixing.
    What's the best way of turning the treble-cut tone controls into a bass-cut?

    I do use treble-cut from time-to-time.
    But always thought bass-cut would be infinitely more useful.

    Best Regards...

    They would give you more treble.
    Here's a circuit that isn't used much anymore. It cuts or blocks bass frequencies. And only lets trebles through. I'd suggest a 500K pot. Although any would work. I'm not sure what value cap you should use. You could try various ones and see which you like best.

    I would measure your pot values first then take it from there. If they are around the typical 300K that Gibson is known to use then move up to 500k. YOu could even move to somethig like an RSguitarworks electronics kit. People seem to really like them.

    How is that a "kinman" treble bleed mod? It sounds just like an ordinary treble bleed mod.

    I associate the cap and resistor in series with the "Kinman mod".
    As opposed to them in parallel.

    From this page:
    http://www.projectguitar.com/tut/potm.htm
    I could be wrong...
    Regardless, it's revolutionized the volume control for me.

    Btw EADGBE, thanks for the bass-cut circuit!

    For your purposes try bypassing the resistor. You can just short it out with a jumper to experiment. That may give you more top end, more quickly, as you roll off the vol.

    that bass cut circuit is very cool, i've seen it at the seymor duncan forums.

    the suggested values were a 500k resistor in parallel with a .01 uF cap. this gives a roll off frequency of about 30Hz, which is perfect for taking out the muddiness or 'woofiness' from some neck pickups.

    I wonder if this "bass cut" idea is anything similar to Reverend's "bass contour" contriol?

    .01 seems to be high (valued)
    30Hz seems to be too low as a target
