Please confirm or deny. Please let us know if your already excellently designed analog delay has been updated to increase the modulation a bit. I bought a new one a day or two ago and I swear the modulation is slightly more pronounced and the delays are quieter. It sounds better overall than the orginal one i owned when they first came out ( and that one already sounded excellent - now they sound frickin brilliant ! )... Can you please let wondering minds know ?? And also what serial number did the upgrade start at ?? Thank You !
