MM4 doesn't work properly (LEDs blink, nothing happens)

Recommended Posts

Hello,

my first thread ever in my first forum ever: be patient.

 

I bought a second-hand MM4 a couple of years ago. In these two years it has been powered by batteries for a short while, then by a Gator power supply 9 V DC. Everything was fine so far, both in function and from the power supply point of view.

 

End of July I was rehearsing with the usual set-up, some tremolo effect was on. I switch this effect off and after a while choose another switch: the sound doesn't change at all (volume, color, etc.) but on the other side the LED of the button I stomped on started blinking at a slow pace (on-off-on-off-...).

 

Since then, it didn't work anymore. I tried restoring the factory setting (the two outer switches), but it didn't work at all: nothing changed. I didn't try supplying it by batteries because it's "ultimately" stuck to the velcro and I don't want to destroy the pedalboard before I know what to do first.

 

What should I do? Thank you very much.

Giorgio
