Other clues in old gear, in general, are date markings on integrated circuits like op-amps, which can help estimate the age. my MP-1 has a NE5532 chip marked with two lines: "NE5532N" and "8605D". I debugged it myself to uncover the root cause, and then later discovered they fixed it in a 1989 revision in exactly the same way.
I'm guessing that you might have seen this fix and are wondering whether you have an older one.

IIRC, this is written close to the power entry connector.
If your MP-1 has a top-switch, it's one of the old ones, like mine, from circa 1987. The old ones have a design flaw which causes them not to start up sometimes when powered up.
I have one coming my way that I'd like to boost with a TS-808 and TS9This is for an extreme metal, thrash, technical metal tone.
The seller had it serviced and it has a Voodoo mod done on it but not sure which one.
ADA, which is legendary for both its vintage MP-1 preamp and classic flanger, took a very fundamental, front-end approach to tone shaping with the APP-1.
The APP-1 takes two Fender Twin-style tone stacks and pairs them with ADA’s patent-pending D-Torsion Core technology, which is designed to help tailor an amplifier’s reactivity.
My chain would be guitar-tuner-TS9-ADA MP1-ISP Decimator in the loops-Boss GE7 EQ-Torpedo Live Do you guys think I can pull off that kind of tone with the ADA MP1?

Take a listen or plug in now In short, we’ve shrunk the package, but kept the tone.
Check one of the many online videos or visit an ADA Dealer to hear how good a pair of tubes can make you sound.
