Hi,

Does anyone have the Electro-Harmonix English Muff'n schematic?
I can buy one 2th hand but would like to see from the schematic if it's worth modding to a marshall 2203 like preamp pedal.
If the schematic is too far off , ill drop the deal.

EDIT: If anyone has pics of the inside, I welcome those as well... :applause:

Anyway, thanks a lot in advance.
regards,

Frank

Hi, bought I am tube effect English Muff"n. Isn't perhaps hopping in good order. At tail tone are there some unsightly stridor. I was trying change vacuum tube, but result is same. Cannot be somewhere punctured capacitor ?
Apologize for my bad English.

Thanks for yours answer.
I am recorded new example, where they are highs and mid fully.
V the tail is of such bad solid state distortion, Is it indeed in good order ?

Thanks Tom
