Electro-Harmonix Big Muff Pi V9 Early version EC3003 - A board

Description

Early Big Muff V9 from the early 2000’s!
IMO and many others is the best sounding Big Muff ever made!! Early EC3003 - A board.
It is excellent/mint condition.  Works and sounds amazing, see pics for condition and will ship quickly, safely and insured.  No mods have been done to this unit, all original and includes original wooden box it came in.  I bought this new back in the early 2000's where it went into a box during a move only to be rediscovered now.  So it was barely used.

CIRCUIT - In 2000 the first edition circuit board was marked EC3003 and used four 2N5088 transistors. Tone sucking when in bypass mode was a common complaint about EHX pedals, and the "true bypass" fad was beginning around this time, so a true bypass foot switch was added with the EC3003-A revised circuit board later that year. The component values appear to be a mix of a late 1970s V2 BMP, with a deeply mid-scooped tone section from one of the early V1 BMPs, and 390Ω emitter resistors in the clipping stages from a Sovtek BMP. The 3003-A revision from 2001 was basically the same. Previous USA Big Muffs used 1N4148 Silicon diodes, but EHX changed to 1N6263 Silicon Schottky diodes for the reissue in 2000. EHX changed back to 1N4148 diodes around 2008. 1N4148 compress the sound a bit more more, giving a sharper sound but with slightly less treble than 1N6263, partly contributing to the different sound of the reissues.
In 2007 the board was changed to a third edition EC3003-B schematic with BC550C transistors. In 2008 it was changed to a fourth edition EC3003-C schematic, also with BC550C transistors. The EC3003-C revision changed the volume pot to a 500k logarithmic taper pot, though the tone and sustain pots remained 100k linear taper as on previous Big Muffs. There were also 3003-D and 3003-E circuit revision between 2008 and 2013. Most of these revisions did not affect the sound much, but there is a big difference between the original 2000 circuit and the version from 2007 and later.
PACKAGING - These originally shipped in a wood crate but later changed to a 3-color corrugated cardboard box that matched the style of the old V3-6 Muff boxes, presumably to reduce the manufacturing cost. "Your piece of the pi" was printed in the inside box lid flap.
