Don't know why EHX pedals have this weird non standard 9.5v and 9.6v inputs for their pedals. I got the Memory Boy Deluxe and tried it out, no sound (how ironic) so i tried 500mah 9v one (you know it's over powered for one pedal) and still no sound until i turned delay gain all the way up and blend basically all the way up then i heard a hair of delay. well this situation is not ideal at all. then i got this one EU96 and it works all most fine. To make matters worse, on their website they say basically random Boss or Ibanez replace, that's plain right false information. You could accidentally plug this to other pedal and fry it up. Should also mention that this isn't one of those slim nor sleek it's pretty bulky and heavy one.
