hi, thanks for quick reassuring and informative replies.

I intended to mention that they are 'brand new' completely unused
never taken out of their boxes..
[but that got accidently edited out whilst copy & pasting]

..so I'm trying desparately hard not to remind myself
they cost a total of about £1600 of Band development budget
back then..

Another thing thats just occured,
possibility the Harddrives might have seized up due to inactivity..
so they might need to be replaced !!!???


btw, this has also reminded me to search in storage for an active Bass guitar
and a strat copy with active pickups that haven't had a battery health check up
in the last few years... oh bugger...
