stripped down Dumble tone stack

Post by stephenl »

I wanted to try a simplified version of the tone stack in the John Mayer Sig amp...
Do I have this right? The part I wasn't sure about was removing the DEEP control from around the BASS control.

That looks fine, but you can replace the 0.002u, 2M2, and 1000p with a 680p. There won't be any significant difference.

Looks like you’re missing a mid cap.
If you are not using a mid boost, you can eliminate the .002uF and 2M2 and choose what ever pF treble cap you desire.

A pretty subjective question, but...
For the "typical" Dumble clean sound, are the bright, mid-boost, or deep circuits commonly engaged?

Depends I guess. I usually have rock and bright (100-120 pF) engaged. I tend to look at jazz mode, mid boost and deep as additions to the Dumble tone stack.

And indeed the drawing is missing the 10nF mod cap.

By the way, imho with a Mayer clone minus all the additions you’d be better off with a classic tone stack. I never really bonded with the Skyliner in combo with low plates and a strat. Ymmv.
