  • Mega-Maggie Mods? Magnatone MP-4 from 1965-1967

    Any one know any info on “Mega-Maggie?”
    There’s really not even much on these amps. (A fuzzy schematic for the mp-2.. anyone got full res?)
    I was told the first two are cathode bypass switches. Kicking em on increases the gain for each channel individually and in channel one sets a real nice tone. I’m not entirely sure what the switch all the way to the right does, increases gain but acts on both channels. I haven’t opened it up yet, should be easy to tell as everything here is p2p but just for the life of my research, couldn’t find anything on mega-Maggie. And since this amp is from 65-67 there’s a whole lot of hands that could have seen it since.

    Also, any additional info on this amp would be cool if anyone knows.

    (I know I really should open it up and it would answer my “what is the switch doing” question... but also kinda curious, what if mega Maggie is someone in here?)

    Thanks,
    Trip

      I think the M4 and the MP4 are very different amps.

          Hey, I ran across this thread while looking for another Magnatone model. I know a guy that knows a guy type thing - lol - anyways, here's a schematic for the mega maggie that should be real close if it's the same amp - looks like the same amp from the picture. Hope this helps, man. Have a good one...



          Hopefully I uploaded the pdf correctly, so you can see it...

              I just picked up an mp-4. Mine is torrance, CA so i assume an earlier model. A site i found says they introduced the pro series line in 1966, but then states estey moved to PA in 1965. Hmm. Also, mine has two holes drilled in it in a similar spot to the ones in yours!! Someone "went through" mine and made it more "guitar friendly" according to guy i got it from. I wish they would have left it alone. However it looks pretty original. I need a front panel/grillcloth assy which im sure will be next to imposibble to find, as well as a few correct control knobs. Let me know if you have any resources.
