Hi,

Is there any way to tell when my MP-1 is produced?
It says 1.38 when I turn it on, has the line/instrument switch on top of it and serial number 805284.

Probably 88. Take the top off and in the right back corner where the transformer connects to the main board you'll  the date of productions and (Rev) and a letter for what board revision it is.

MarshallJMP:
Yes 88 seems also correct to me.

martinmarkvoll:
Thanks guys! You were right - 1988, rev D.

Hey Martin - I just got serial 805299.  Guess ours were probably made the same week :)
