The Strat Plus and Plus Deluxe models use a Fender TBX circuit for the
bridge/middle pickup tone control. I think the American Standard does
too. It’s available for $25-$35 from Fender dealers, according to a
phone call I made a few weeks ago for another reason.

There’s a circuit diagram for the TBX in A. Duchossoir’s book _The
Fender Telecaster_. It uses a dual ganged pot with 250K audio/1M
linear resistances, an 82K resistor and a .22 MFD tone capacitor.
>From 0 to 5, it’s a normal 250K treble rolloff circuit. From 6 to 10,
the 1M resistance keeps some of the highs normally lost by the 250K
circuit. I guess “add” means “doesn’t lose as many as usual”

There was a posting here a few weeks ago about using higher
resistances in tone and volume controls to increase the volume and
highs you get from a pickup. The TBX is a clever way to apply this
principle in a single, relatively intuitive control.

I like having the TBX, but I find that if I want my Strat’s 2-pickup
combinations to sound “twangy” to my ears, I have to stay in the 0
to 5 range. I guess 250K pots are a subtle part of the traditional

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.

Playing "Help-Me" In the Style of Sonny Boy Williamson II: A step by step, note for note analysis of some of Sonny Boy's Signature Riffs

I also write Science Fiction, so you can sample some of my best stories. Also available in Kindle format.

I began collecting data about the microphones used by blue harp players before there was an internet. I began organizing it into in the late 1990s. I accumulated more stuff than I remember. This is some of it.
