Picked this up earlier this year as I thought the shimmer feature was cool, but realized I never used it, so I went back to my Stereo Wet Reverb. Excellent condition. Not sure what makes it B Stock as I can't see any flaws, certainly nothing that affects performance. Great Reverb with "Choir of Angels" Shimmer effect. True Bypass. Original box. No power supply. $150 plus $13 shipping to the US. (Will ship internationally - USPS Medium Flat Rate Box) PayPal only. PM me if interested.
