I have a dilemma. I have the chance to buy one of two used Martin 000-15M guitars - both are immaculate. One is the standard model and the other has the limited edition factory fitted Fishman Thinline Gold pre amp and pick up installed (000-15ME). The ME model is selling for £50 more. I rarely require a pick up model and wasn't looking for one but now that its there and not much more expensive, it's made me question whether I should go for that? To be honest, I'm thinking probably many years down the line, should I ever re sell, which would be more desirable then? Overthinking things as always but would appreciate any thoughts and comments. Thanks.
