It looks like a basic Fender with the mid turned all the way up (since there is no mid), you can easily replicate it online with the TSC calculator. (Keep Mids all the way up)
I think R21 (2k7) resistor is in the Mid pots position so you can change the mid dip by changing the value of R21, or even installing a pot instead of R21.

Here is the sweep setting with a 25k pot for R21, the pot gives you a working mids control.
A 25k pot allows it to be nearly a flat line for the tone control with mids on full.
With a 5k pot you would have the standard Nobelium with the pot at 12 o'clock.
