    Hi All,

    So the other day, a friend of mine borrowed my MMWH, called me and said – “is it supposed to start looping on every delay setting? I cant tap the tempo in either” This friend is competent – he wouldn’t have used the wrong power supply etc.. The delays sound right, but, as he said, tap tempo does not work and the loop is always on.

    First thought is there is a short/fault with the tap switch, as the pedal is behaving like it is held down. But I opened it up and tested the switches for shorts/continuity and found nothing wrong.

    Tracing this any further back into the circuit will be a real PITA as it is all SMD components in there…

    Anyone had something like this before? Anyone measured any voltages?

    Any help would be greatly appreciated!

    Cheers,
    Tim

    Hi Tim

    Hmmm I know when I first got mine i sort of panicked because i couldn’t stop it looping but some careful reading of the instructions does help. Click it out off effect and then hold down the tap tempo/loop switch for a second or so and the looping stops. I don’t know if this is your problem or your friend just didn’t know how to do this. Hope it helps.

    Hi Brian,

    Thanks for the reply, I should’ve added that I’ve had the pedal for a few years, gigging/touring with it constantly about 4 gigs/week.
    Very aware of the functionality of the pedal, hence the reason for my post..

    Cheers,

    Tim

    It does sound like the TAP FSW is always engaged. Do you have a voltmeter? While the pedal is powered up, what is the voltage across the two pins of the TAP FSW that are wired? It should be approximately 3.3V. When press down on the TAP FSW, that should change to 0.0V. Sometimes it is easier to see a fault with a footswitch while the unit is powered up rather than measuring impedance.

    Hey Flick,

    Thanks for the reply..

    I’ve done some readings..

    I’m reading 3.3V DC at the terminals you mentioned. 0V DC when the switch is engaged.

    I’m reading 5VDC across the 7805 (U13)

    1.3V +Side of D14 to GND
    2.5V +Side C1 to GND

    The markings on the PCB are dated 20th March 2007 Build 1

    Thought my Christmases had come at once when I saw the Deluxe Memory Man w/ Tap – but no longer avail right? Will it come back?

    Thanks..

    All those voltage readings are correct but I’m baffled as to why it is acting like the TAP FSW is being held down. I think we’ll have to look at this unit.

    OK then..

    I’m in Australia, where should I send it? It pains me to think of replacing the unit when everything seems so close to being right….

    Cheers,

    Unfortunately we don’t have a repair center in Australia. It looks like you will need to ship it back to us to fix it.

    I’m having the exact same problem! Was this resolved? Thanks.

    No it wasn’t! End up borrowing one when I need it these days…
