Home › Forums › Vintage EHX › Little Big Muff EH SPI Info ?
I have a Brown & Yellow Little Big Muff Pi version marked “EH SPI” on PCB.
I’ve already heard of the “EH 3034” and “EH 1322” PCB versions but never of this version.
By looking at the PCB, it seems to me that it is not an op-amp / IC based version but a transistor one.
Any information about this version, its date and how it relates to other BM and LMB version would be greatly appreciated..
Thanks for your expertise !!
I have one of those — BC239C transistors and 1977 pot codes.
Post pics of yours?
Thanks for your answer !
Mine has the same PCB and the same transistors and white box caps as yours and it dates from 1976 according to the pot code (137 76 07).
Here are the pics:
Usually Little Big Muffs share their PCB with Big Muffs and this Little Big Muff transistor version is contemporary to the Big Muff Ram’s head and V3 version.
Is there anyone who knows if the EH-SPI board has been used in some Big Muff Pi version or if it is specific to the Little Big Muffs?
I’ve never seen one in a full size muff.
Seen plenty of Muff boards in Little BMPs though…
Hi I have the exact same pedal just in pretty rough condition, my upstairs neighbour had a burst pipe and I got flooded and some equipment got wet. I am currently repairing my LBM and I need a picture of the wiring of the amp and instrument out puts to see if I have any wires missing through corrosion. I am missing the 9V battery clip, but that’s an easy fix. The amp output looks like it’s missing a wire as there is only one connected when I would expect two and there is only one.
Any help would be appreciated,
