The PCB inside these pedals is identical to the full sized versions it just turned sideways. If you want to adjust the tone and sustain you just adjust the value of a few resistors that set the tone and sustain to pre determined levels, or in the case of sustain if you want it on full you remove the resistor all together and jumper it from lug 3 to 2 where the pot would normally be.

For the tone, its good to have a 100k tone pot to hook up to it, set it how you like it and then measure the Kohms on it, then you can make fine adjustments on the tone switch once you know what value resistors to use on the switch.

These pedals came in both the 3034 transistor version and 1322 IC version.

Congrats, DiscoFreq!

Those reverse graphic LBMPs don’t come up very often. I’ve seen them maybe twice in the last few years. The blue is so much sexier than the brown and yellow fudgepop versions. I’m guessing that one is an IC version.

hmmm..a bit confused…

i have a bunch of older EH pedals and for that ones age, why does it look like it has a newer type knob? is it correct for that model or was it a replacement?

my Y Triggered filter, and 2 The Silencer’s i have , have the old knob thats round but turn’s almost into a chicken head type, but my newer but still a bit old Small Clone and Dr.Q have the newer knob like that one, but i thought that unit was a bit older to have the other knob.

anyhoo…..sweet find!!

Yes, the barrel knobs were used interchangably with the pointer knobs back in the late 70s / early 80s.
My vintage PolyFlange, Bad Stone, and Deluxe Big Muff Pi all have the barrel knobs.

that little big muff pi looks really cool.

it’s just a basic drum machine, but you can hear exactly what it sounds like here.

I sold mine because apart from it looking totally cool (and being ehx) I didn’t really have any use for vintage drum machine sounds….still I got nearly 4x what I paid for it.
