Mellotronists

On the Cope website - Q&A ... two Mellotrons are listed with his 
favorite instruments....

"...My two Mellotron 400s are in constant use because I have a bunch 
of tapes which no one else has. I bought three tape-frames from 
Tangerine Dream in 1995 (3 sounds per frame) and they will keep me 
going forever. The Mellotrons need a lot of servicing, but they're 
far more roadworthy than rock'n'roll legend makes you think...."
