I noticed this on mine too. I tryed it with a different adapter then the one it came with, and now it works perfectly. I just run it using an Ibanez adapter and I can access the full delay time. wierd huh?

As for the noisey long delay times, I think that’s just from maxing out the delay IC. I have an old DOD FX50 analoge delay, there’s a trimpot inside it that lets you adjust the delay time. After 400-500 ms it starts getting slightly bit crushed sounding and you can hear the clock noise slightly. The longer you strech it out the more it degrades. It can be a pretty cool effect, but I’m sure that’s not desirable by everyone. So I’m just assuming that the full delay on the Mem Boy is probably staring to push the chip. But really, it does have quite a long delay time for a stock analoge delay, I think it might be longer then 550ms even. It’s deffinitly longer then my Deluxe Memory Man.

Hope this helps?
