Friedman OD

[Valvehead]

I have the BE-OD pedal which sounds excellent , but....it has a slight nasaly wha midrange hump. If i could tame that down a little the pedal would be perfect . i do have an Eq pedal i use with it, but it doesnt have the freq to cut. The "wonnk" is right around 630- 800Hz . Can anyone tell me what cap i can play with to cut that ??

Ill try to attach the scem

You'd need a notch filter to cut only those frequencies. It can't be done with a simple cap change. Where do you run Treble, Presence, and Bass controls? It might help to look at it from a different perspective. In other words, instead of cutting mids, you boost bass and treble to achieve the same result. I might start with the existing bass and treble controls maxed out and then back them off to taste. You may be able to get what you want without modding.

Pres 9-10
Treb 9-10
Bass 6-8

I remember removing an electrolytic cap from a Bad Monkey and it def helped the mid hump

Ive got an eq pedal but my mid options are 500 then 1k .. i guess an option is a 31 band

You could try playing with the value of C13. The presence control seems like more of an upper mid control than a real presence control anyway, especially given that the treble control is after it in the circuit. You may be able to turn it into a more useable mid control that effects the lower mids instead of uppper. Then use the presence knob to cut low mids instead of boosting high mids. I can't say what value will work for you (if any). You'll just have to experiment.
