Isosceles bass/treble barely work¿

[jwin615]

Alright, been a while since I asked for help.
I know I should only hear BnT in Pre mode. Both switches are good.
I've checked all values while sober.
Don't get it. I only hear a minimal adjustment. Am I missing something in operation?

Bump for the morning crew!.
Any ideas. Sounds like about 3eb adjustment on both across the entire sweep, like the corner frequency is 60hz and 10khz..
Just noticable. Is that normal for this build?

One last Friday night bump(those were the days).
I'm convinced this is an annoyingly stupid oversight. Checked all resistances in the tone section with DMM. All as advertised...

Hrm. I gave it a look. Nothing popped out at me.

Does boost mode work fine? It’s just the treb and bass controls not doing very much?

 

[jwin615]

well, it was something stupid.
Lesson learned. Busted up Jags don't test metal pedals well. Hear a bigger difference on the Jericho. Need to hear it loud(to late) on a bigger amp
It still seems way more subtle than I'm used to getting from a tone control. But it's working as long as I use a guitar that isn't all mids.
I guess in could stop being lazy and do the math on the corner frequencies...
Nah. It's late.

I'm not sure I'd call the controls subtle but they do seem to affect frequencies that are slightly lower and higher respectively than what you'd normally see in a guitar pedal. I found this post on tweaking the tone control values: https://forum.pedalpcb.com/threads/integral-preamp-modifying-the-eq-bands.14668/#post-171923 It's for the Integral Preamp so part numbering may be off.
