Front panel Pot Placement

[big_teee]

I have limited space on my Hohner chassis Tube Conversion build.
If I use treble, middle, bass, and presence, the presence will be quite close to the PT.
I'm considering dropping the middle control and just having treble, bass, & presence.
Will I miss the middle control in the tone stack, or is it mainly window dressing anyway?
I realize that fender has done treble, bass, for years, but I have no experience with that setup!

I don't think you'll miss it, you can always adjust the value of the mid resistor to your liking. Do stacked pots stick out too far for your liking?

I was considering just hard wiring a mid resistor in place, or put a trimmer inside the cab.
The problem with stacked pots, is most of the pots are different values.
using this tone stack.

I could replace the 25k pot with maybe 2 -13k resistors.
Or some sum of the two?
Most of the time once I get the tone stack adjusted it never gets changed much?
Thanks,

You could use 9mm pots and small knobs e,g Davies 1900H series (12.7mm dia) . Pins on this example rather than solder tags but that is not a deal breaker.

With your trim pot idea, you could always make it accessible from top or bottom side rather than on the front panel.

Thanks guys.
I have all the holes drilled in the faceplate except the last one.
I think I will get it all working, and if the presence has no noise issues, wired temp near the end?
Then I can cut the hole for it, and all will be wired normal.
If worse comes to worse, like mentioned, hard wire on the board, or use a 25k trimmer wired on the board.
Thank you,
