This is an early V9 Reissue Big Muff from 2001.  It's condition is technically flawless with a little cosmetic patina.

It has the old style Daka-Ware pointer knobs that were only used until mid 2001, which makes it somewhat rarer.

The earliest reissues are known as the 'Frantone Big Muff" - Fran Blanche of Frantone was an engineer at EHX at the time, and commissioned to design and relaunch the NYC Muff.  This one has the EC3003-A circuit board, and Davies/Daka-Ware knobs only found in 2000-2001.  The 3003 & 3003-A circuits are said to be better sounding than the subsequent versions.  I would have to agree - it sounds EXCELLENT, and has more clarity than your average Muff.

According to Kitrae's Big Muff history page (please go there for more detailed info):

• 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 first version is the most like the old early 70's Big Muffs, with a bit more note clarity than the later revisions, and slightly less bass. The 2000 and revision A circuits sound the same.
