Thanks....

Neglecting the component values (which couldn´t be read clearly) is it a 1:1 clone of the EH talking-pedal with single opamps (instead of dual opamps).

Thanks, that's interesting!

I can look for values, but the chips have no numbers, just a matt zone in the middle: clean way to cover the numbers, numbers removed? Probably they're Polish/Russian chips, I saw some strange chips in other pedals :)

Russian or Czech chips from Tesla.
I am not aware of a polish chip production - e.g. Unitra/Diora got the parts for ther Hifi/Tv-stuff from russia, czech, bulgaria and even the west.

I checked most values, they seem to be correct, only the 0,15µ on the left bottom corner is µ1M.

I couldn't check all resistors: I should check the colorcodes for some... other have no color codes but the value is sometimes underneath the resistor)

The "?" has an "N" on one side and 80 МЛТ (МЛТ under 80, not same line). Does it matter as it's bypassed by the track on the pcb?


Now I'm curious if the Small Phaser is related to the Small Stone (has extra knobs), the Sustain Filter to the Big Muff, Attack EQ to the EH Attack EQ (probably), Wah Fuzz to the Crying Tone pedals,... The envelope filter has quite a lot of features (filter type, attack,...) that are different from EH pedals, so that's probably not based on an EH pedal...

we are looking forward to new thread?!

on original EH talkingpedal schematic that resistor(80/MLT=80/МЛТ) is missing.......and in PUE Talker it has no function.......so it is some kind of joke?? :? ...they can say ....'It is not exact copy' :roll:

Thank You very very much mister DiscoFreq :thumbsup

I can do that, but I have to search a bit for that one, I saw some other PUE pedals while searching the Talker, but not the envelope filter...
