I own ads of acoustic guitars and even the cheapest one sounds brilliant when passing through the Fishman Tone AFX DEQ.
I must also state that the effects on this unit are fantastic - the delays , reverbs and even the tremolo, flanger and chorus are A Grade!
A must buy if acoustic tone is critical for you on stage and in studio (if DI'ing)
