Tommy III - slightly less scooped?

[nooneknows]

This incarnation of the Timmy is worth every penny, my only complain is it's a bit scooped, even toying around with bass and treble to emphasize the mids.

Any easy mod around to slightly increase the mids?

I would try raising C11, maybe as high as 22nF, 33nF, or 47nF, for an additional treble cut. You could also bump up C3 a bit to increase the low mids.

The Timmy doesn’t have any circuit that scoops out mids. Though I agree it sounds like it has less mids than many drive pedals.

When the signal clips, it tends to exaggerate both low and high frequencies. The clipping harmonics from the low frequencies get bunched up and muddy. The clipping harmonics from high frequencies get really high and harsh.

With the gain down, bass and treble at max seems pretty flat (transparent eq). As you increase gain, you have to cut bass and treble to sound transparent.

The Timmy formula is
Bass cut ( around 1.2kHz), clipping, treble cut (adjustable frequency)

The tubescreamer formula is
Bass cut (around 720Hz), clipping, treble cut (around 720Hz), then a treble cut or boost with the tone knob.

So to make it more similar to the tube screamer, you could introduce another high cut (C11 increase) or move the low cut frequency closer to the TS (C3 increase)

Interesting. I feel like years ago I turned down (or up actually) the bass and treble knobs dramatically on my Timmy and it was pretty mid forward.

There's also the Cast Iron which this forum generally agrees is a Timmy with a Mid control that you might try.
