There are many varieties of "electric", and I think that how they're used depends on the circumstances. Modern acoustic guitars are now often constructed with built-in electrics, or they have had the electrics installed at a later date. I fitted my "0" model Chisholm with a K&K pickup - completely invisible apart from the tell-tale jack socket in the end block - and, played through my Roland Cube amp, sounds beautifully acoustic; just louder. So I've used that in large or noisy venues, or when playing for dancing with the ceilidh band.

I don't see any distinction, in sound terms, between playing an acoustic or electric guitar, as long as the sound is as you want it and (of course) acceptable to the audience. A purely electric guitar, as opposed to an electro-acoustic instrument - your 335 is a good example - often requires or invites a different technique, attack, melody sustain, vibrato, etc., but that's just a matter of practice.

Some folk clubs I've guested in ask you to plug in, if you can, and have a suitable amp or PA system for you to do so, simply because of the size and acoustics of the venue. If I recall correctly, the Ram Club in Thames Ditton - a very successful club - is an example.

So, Al - have a blast!
