Hey all, my dad is seeking advice on which amp would be better. He is a guitar player since he has been a little kid and has been in many different bands. When it comes to buying guitars and guitar related equipment he ussualy knows what he wants and then finds something affordable. Now however he could use an advice. He wants to buy an amp for his Ovation Custom Legend acoustic guitar. He has narrowed his choice to Fender Acoustasonic 90 / 150, Laney A1+, Roland AC-60 and Marshall AS50D. Any advice would be much appreciated.
