1015.0. "Source of pots with push-pull switch?" by ROLL::BEFUMO (I chase the winds of a prism ship) Mon Dec 12 1988 10:49

    Does anyone know where I might find potentiometers with built-in
    spst push-pull switches?  Thanks.

1015.3another pot questionsBUSY::JMINVILLEFri Feb 14 1992 15:0512
    Is there a type of push-push swith that would give me a 250K volume pot
    in one postiont and a tone pot in another...
    
    Are tone pots rated the same (e.g. 250K, 500K, etc.).
    
    What would be the best tone pot to use for a S-D HotRails Tele pickup
    and a Gibson '59 humbucker?
    
    I've read that 250K volume pots are best for 'buckers...but what about
    tone...?

250K are not best for humbuckers, 500K to 1Meg are best for humbuckers unless
you like your treble to go away as you turn the volume down.

250K's are for single coils.

1015.5Master Volume/Master ToneBUSY::JMINVILLEMon Feb 17 1992 13:1321
    Thanks Dave.  So, 500K to 1000K are best for humbuckers.  Can someone
    explaing to me, in musicians terms, not techno-weeny speak, what the
    different ohm ratings for the pots actually do??
    
    What I'm ultimately trying to get at is controlling two humbuckers
    with only two knobs: one volume, one tone.
    
    I initially felt that dpdt-type pots might do the trick...the double
    volume pot could handle both pickups as would the double tone pot and I
    would have individual control over volume and tone for each pickup.
    
    I was going through some GP back issues over the weekend and I saw a
    good article by Dan Armstrong in the November '87 issue.  It is
    entitled, "Master Volume Master Tone" and it describes converting a
    4-knob set of controls to two.  It made me think that perhaps I don't
    need a volume/tone control for EACH pickup, but that single master
    controls might do just fine.
    
    Anyone have thoughts/experience with such a setup?
    
    joe.

Yep get some 500k or 1M pots and wire 'em...

The resistance is essentially analogous to the diameter of a pipe, the higher
the resistance, the narrower the pipe (electrons of course would then flow at
some rate called current). Higher resistance pots keep your pickups from 
getting loaded down, which usually causes some loss of high end. (Most
everyone has probably played a les paul or some other humbucker equipped
guitar that lost it's high end as you turned down the volume, my tele thinline
has this problem in spades even with 1M pots installed, poor pickup design)

you could just wire the single volume and tone pots after the switch vs. in 
front of the switch and they'll be masters rather than a pair for each pickup.
