I started using a Parker Dragonfly back in the summer. Fishman bridge into an acoustic
combo for 'acoustic' sounds and mixed with mag into valve amp for 'semi' sounds or mag
only for 'solid' sounds. Works fine in a mix although I'm thinking of simplifying the
signal chain a little by dropping the ability to blend the two signals (done via a Boss
LS-2 line switcher pedal).
I've also had good results in the past using a
magnetic pickup into a Boss AC3 acoustic simulator pedal / acoustic amp which is probably
a cheaper solution.
