"Can any of you experts tell me what is a good electric guitar to play slide on, or does it matter?"


Yes..


ANY electric guitar that has too worn or uneven frets
that you cant afford or be bothered to have refretted..

and/or a bad factory set up uncomfortably over-high action..
[cant be bothered filing down or replacing the nut..?]

so easy solution.. raise the action as high as you can..
and you get instant electric slide guitar..


at the moment my lousy action worn out fret electric slide guitars
are an early 80's yamaha sg200

and an early 90's squier silver series strat
[very nice guitars.. maybe i should get them refretted..???]
