EHX LPB-1 toggle-able Treble Boost?

[nascarbean_97]

So, basically, I was wondering if there's a way to switch two sets of two caps at the same time, with a dpdt switch. I'd like to mod my lpb-1 into a switchable treble boost, and that's what I'm stuck on.
Worst case I'd just use two dpdt switches.
Thanks!

I think you answered your own question bro!

Why two sets of caps? Just put a switch in series with the input capacitor and put a 4.7n cap in parallel with the switch and input cap.

Thanks for that last suggestion, but I just realized think i'd rather use two switches to try to get other than only treble boost or clean boost.

There's room in the box 'cept for under the bypass switch. Might as well socket the caps then I guess.

here is an unusual approach:

use two stereo jacks. make the output jack the one that turns on the battery. the input jack could have two modes. plug it in all the way = full response, plug in partway, =treble boost. simply wire the two caps together on the trans side, and each cap's other end goes to tip ( large cap ) and ring (treblee cap).

edit, i just realized that if you did what i suggested with a normal open stereo jack, the circuit would short to ground when plug goes in full. a switching jack could be used, however.
