Decisions, decisions ... I own a Martin D28, great acoustic guitar but I want to use it in live situations and need to amplify it. Someone suggested a Fishman rare earth pickup, which seems a good idea but ... the installer needs to widen the straphole a little (to put the Fishman jack in). Now, should I do this? Is a strap on microphone a better idea? I am really not a fan of 'widenin' the hole a little...' Is this a good idea on such a great instrument? Please give me your advice (the gigs diverse from bars, churches up to big open air stages for several thousand ppl) ... Thanx for your great advice!
