    I just received my memory boy I ordered from Musicians Friend early on today. I found out that the pedal will not work if the delay knob is less then half way turned up. I’ve continued to try it but still have the same problem. I am wondering if I should send it back.

    I had a different problem, but here is how I fixed it: With my MB, I found that any feedback setting higher than 12 o’clock resulted in immediate and very loud self-oscillation. Below that, there were hardly any repeats. It was all or nothing. I knew that it was wrong–that I should be able to get more our of the feedback before it self-oscillated. For the record, I play a Stratocaster and was just playing the delay with no other effects.

    Reading the comments here, on other threads, and in other places around the internet, it appears that my problem was unique. Most people seem to have trouble getting any oscillation or repeats. Generally the suggested fix seemed to be use a battery or the a/c adapter that came with the pedal. I, however, was using the a/c adapter that came with the pedal, so since I had the opposite problem, I tried the opposite solution and plugged the pedal into my daisy-chain a/c adapter, the one that came with my pedal board. Bingo! Now the pedal sounds great, perfect and just like it apparently should from the demo videos I’ve seen.

    So, the upshot of all of this is that I would suggest trying different power sources. Obviously, there are some that will hurt your pedal, so don’t try those (yet) but try different batteries or a/c adapters. Good luck, it is a great pedal when it works.

    It has been my impression based upon personal experience and participation in this and other forums that – for some reason – there have been a number of units that have arrived mis-calibrated. Perhaps rough handling is causing the trim pots to move around, perhaps one of the calibration scopes was itself miscalibrated.

    If I were you I’d ask for a return/exchange.

    Adding to my theory of the mis-claibraiton is that when I purchased mine it was quite out of whack. Instead of returning it I contacted EHX, which replied it was still under warranty and to send it in. Upon getting the unit back a week later (and it was the same unit based on the serial number) it worked just fine…

    Hey, I’m having the same problem as you were, but I tried what you tried (plugging it in to a daisy chain adapter) but nothing was different. What do you think I should do? This feedback problem is getting irritating- the Memory Boy I tried at Guitar Center didn’t have this problem whatsoever.

    Here is the full problem I have been having. When I first turn the pedal on, I have to turn the delay knob up the whole way for it to work at all. After its on for awhile, i can turn it half way back. After I wait even longer, i can turn it almost three quarters the way back to the beginning. All of this is after a few hours, and if its turned off for a while, I have to restart the process. But, its never let me start low on the delay knob. It looks like I will have to return it like the second person that posted suggested.

    If I remember correctly, the instructions that came with mine said that the pedal must warm up first–for 20 seconds perhaps. This may be what is happening–you aren’t letting it warm up first.

    I don’t know. If you’ve tried the adapter it came with, a different adapter and batteries, perhaps it has the above referenced calibration problem.

    I’m having the SAME problem with the feedback setting. Also, the expression pedal is completely out of whack too. There seems to be a need for a recall of units. Also, I was disappointed to see MADE IN CHINA really big on the inside of the pedal….

    i bought this EHX memory boy from ebay about 3 months ago. The feedback seems to have problem. But only with adapter, because when i used battery it’s work fine.

    anybody can help?
