I own a YJM Model head. It has an issue with the digital board processing (part # MD55-66-00-1SS3) and i just can´t reach Marshall´s support to get this part. I´ve sent an email but had no response. By phone they will never call me back as i live overseas...
I live in Brazil and don´t know if there is a Marshall Support around.
Please, help me out.
ProShows are our distrubutor in Brazil, you would need to contact them for information regarding this part.
