| Hi.
IIRC both Yamaha and Roland used that kind two width pinstriping at some time in the 80's, but to my very limited knowledge of the products of those companies, neither of 'em were yellow.
Boss yellow is pretty close to what You have there, so my guess would be Roland in any case.
Inside pics would help...
The only "Marshall" part is probably the logo, the headbox doesn't seem right somehow.
Regards
