Hello again:

As I posted last day, I’m still “trapped” with the same problem. The past week, my guitar tech and me have been testing and checking values of chips, resistors, and any components of my DMM.

Looks like science fiction but, despite our efforts… the problem stands still.

The weird thing is that the effect sounds and pots interact when you tweak them. But the output level cannot reach the bypassed level, except for the self-oscillation feedbacks which goes over the top as usual when we make them.

Any idea of what could be wrong?.

I may take some photos if could serve as add. info.

At the present time, we’re working with my other two DMM’s which work OK (a 2003 “Pre-True Bypass version) and a 2.007 True Bypass version. We hope that comparing the circuitry and testing the sounds we can get the solution.

I’ll keep you updated for fresh news.

Thanks and regards from Spain.

Hello:

Finally, we’ve solved the problem. It was a wire, which was in poor condition. So the solution has been cutting and re-wire again. Also, the incoming voltage was too much, so it has been adjusted in order to avoid future troubles.

But, the mystery continues: Yes!, when I set the delay time at shortest levels (from minimum to the mark located a 6 o’clock) I can hear a hum, but once i set the delay time knob past this value, the humming noise disappears. It’s a low frequency hum (similar in “tune” to a low G).

Also, when I made a self-oscillation, if I set the delay time from minimum to 6 o’clock mark, the oscillation doesn’t appear immediately. But if I begin to tweak with delay knob past 6 o’clock to longer delay settings, the oscillation goes OK.

The same trouble has my 2.003 Deluxe Memory Man.

I think this is a matter of “fine” adjusting, but does anybody have any suggestion or tip to start?

By the way, my 2007 Deluxe Memory Man doesn’t have this “problem”.

Thanks a lot.

Regards from Spain.
