Guitar???

Nice equipment. Just curious I used to have a JMP 100 watt lead head that was identical to the Marshal you have pictured there eccept mine only had 2 inputs not the 4. I have never seen a JMP head like mine. either they have 2 inputs and the light up plastic power switches or they have 4 input and the metal toggles swtiches with the little square light. Never 2 inputs and the toggles with square light. Do you know why this is or have any info about it. I have looked even at Marshall history websites and nothing. thanx.


Marshall changed things up a bit--seems like random sometimes. If yours said JMP on the front, and had 2 ins and metal toggle / standby ....id say it was around a 75-77' .

ive had a 78 JMP-had 2 ins and the plastic switches . Also had a 73' with 4 ins and metal toggles .

Theres a gray area with those amps----which is just another "cool" factor about them. I havent seen a 2 input with the square indicator myself !



By the way---if any of you have older tube amps that need servicing / re-capped/ rebuilt / modded etc...

Thats my hobby and "part-time side job" . If you cant find anyone local that does great work , send me a pm . I can also provide references .
