how to reduce treble on EMG DG20 guitar

ToneControl

I have a strat with a DG20 scratchplate (i.e. 3 EMG SA pickups and active EQ: scoop and mid boost)
I really like this sound, but occasionally would like to roll off the presence-type high treble
What's the best way? I can't replace the pots, can only add stuff somewhere

The easiest way would be to use and external eq pedal, like a boss ge7.

You can get a push \ push 25K pot ...... I have one on my EMG guitar. You could wire it so tone control up adds a treble bleed cap to earth

The boring and obvious answer would be to have a passive treble roll off control.

Unfortunately, EMG passive tone controls never seem to do very much. On the old, hard-wired type, it was possible to remove and replace the capacitor. On the Solderless PCB versions, it is not.

I get my DG20 type sounds from a modified Charvel Model 3. This has two EMG-SLV and one HA pickup, running through a volume pot and an -SPC mid booster. When I want a smoother tone, I pick nearer to the end of the fingerboard.

On the solderless PCB type you can solder to the point the pot joins the PCB. I fitted a Zack Wylde set to a single vol and tone guitar last week and simply ignored the stupid headers and just soldered to the pot lugs to achieve what I wanted

Is the treble boost totally out of the circuit when rolled off?

yes, but so is the rest of the sound
it's a bit odd, it's like you're adding a scooped mid Blackface kind of tone, then adding some mids to thicken it
end result sounds great, but then you can't lose the treble without changing everything else too

This is why I put separate bass and treble EQ on a guitar I specced myself

I haven't looked inside this one for 10 years I think
IIRC it predated solderless, but the controls are all in one block I think

something like this:

I thought to just add a passive treble cut somewhere
There's not really any space left for more pots

Ged Green said there was some little flat wheel one you could get that just protrudes from under the scratchplate

You could fit a Gilmour type bracket / toggle switch which engages a capacitor?

yes, good idea
but is it easy to predict the best component values to use?

SteveRobinson

You could try different values across the jack until you found the one that worked.
