Just picked up an Ibanez AD99 delay off of craigslist for a stupidly nice price (the enclosure is beat). Everything seems to work, but the repeats are very dirty--they sound almost overdriven. I have some experience with analog delays--I have a Jacques Prisoner currently, and have had one of the DOD analog delays, a Guyatone, and a RI AD9. None of them sounded this "brown," and I was wondering if maybe there's something wrong with the AD99. Thanks in advance for your responses. . .
