    Hi, I have rather stupidly messed about with the trims on my memory toy and now cannot seem to get any wet signal. The pedal still works but it is only the dry guitar sound that comes through
    Any help or ideas would be really appreciated but I understand that I may have screwed it
    Cheers

    TB123, I found trim 1 did that to me ( I first thought the trims were screws!) Try it a little to the left, or a little at a time until you have it. After adjusting trim 8 ( a bit to the right) the mod is great-useable and musical. With regards to the EH tech guy, could you provide us with what each trim does? Mine sounds good but I bet I could dial it in even better because EH just cant afford to spend too much time on each one. That hissing is not make or break, but maybe could be improved- the carbon copy is way quieter, but not as musical or as fun as the MB.

    I like mine, but the mod control is a bit whack outta the box.

    In my opinion, the mod trim is set correctly out of the box. For me the most useful purpose of modulation switch is to add a ‘chorus’ type effect. This is normally 20~30ms. If the mod width was set any lower, you wouldn’t have enough pitch shift. Above 30ms, you get into slap-back territory. And I personally have no use to modulate slap-backs or longer echos. Therefore, if you keep the delay time set very short (<30ms), the pre-set mod width works very well out of the box.

    HI All
    Great Forum!!

    I am a compitant electronics tech having experience(I thought!!!) but cant trace the circuit well enough to work it out for myself-how sad!!

    Cheers All

    I see this thread has been dead a long time, but I’d like to clear a few things up for any future visitors.

    I want to make these things very clear…. I’m no expert, but from using common sense based on the knowledge I’ve gathered. Not everyhing I say is correct, and I wont be held responsible. TWEAK AT YOUR OWN RISK. ALL OF THESE POTS ARE SUPER SENSITIVE AND WILL THROW OFF YOUR SOUND IF ADJUSTED TOO QUICKLY/NOT PRECISELY
    .
    1 -trim pots 1-4 affect the Bucket brigade stuff in the circuitry. Im pretty sure that by playing with those, you’ll be messing with the output of each channel of the delay path. Skippy delays or no sound happen when you mess those up.
    2 -trim8 is the mod depth. Go ahead and play with that. Its just a depth knob.
    3 -trim5 let’s you play with the output of the unit in general, if you find your pedal has a volume drop/jump when engaged, play with this.
    4 – i think Trim6 has to do with balancing the bucket brigade (pots 1-4). I strongly advise you NOT to touch it.

    If your pedal is outputting delays as usual aside from unity volume issues (volume jump/drop when turned on) then DON’T TOUCH ANYTHING other than trim8 for mod depth.
    If you can’t hear anything when its on, leave everything alone except trim5 (gain/volume)
    you really dont need to touch anything other than the trims from depth and gain/volume IF you even have a volume problem.

    Trims 1,2,3,4 and 6 shouldn’t be fiddled with unless you’re having serious issues and have already voided the warranty… But doing any of this will void tour warranty so BE CAREFUL, TWEAK AT YOUR OWN RISK, ONLY ADJUST THINGS IN SMALL INCREMENTS
