Mellotronists

I would imagine a lot of folks have big amps boasting hefty speaker 
magnets right alongside their 'trons, Chamberlins, Echoplexes, 
Rhythmates, Studer decks or whatever--so time to give 'em a bit of a 
buffer zone. Anything placed on top of a M-400 is mere inches from 
the tapes under the lid, y'know...

Just beware of 'trons offered for sale from Chernobyl or 3 Mile 
Island I guess.
