Original owner - one of my first modded pedals purchased from Ron Neely directly while I was in college in 2002. Ron performed his Hair Pie mod which was massively interesting to me at the time (pedal mods were new, pedal markets were in their infancy, Big Muff mods were uncommon, Ron Neely was the expert, and vintage Muffs or their clones were unobtainable) and did not disappoint. This pedal is battery powered only. Tested immediately prior to listing and in perfect working condition. Thanks for looking!
