I have two S series (small body) Avalons, one a 14 fret and the other a 12.
Both excel with fingerpicking, punch it out flat picking, and I've never received any complaint whatever from strummers, though they are admittedly only really excellent strummers compared to the magnificence of the other two!
Don't make the mistake of writing off the L320c as only a strummer. This isn't some oversize blouesy boombox . There is one of these lovely Avalon jumbos in the house as well. Believe me the cutaway isn't just there for show, you can play clear articulate, perfectly intonated fingerstyle down there, just as you can all over the neck.
However, if you really want to dig in and strum hard, then prepare to receive complaints from banjo players and drummers about your volume, but you surely won't be getting any about your guitar sounding overdriven or 'muddy'.
Look at a few of the player on the Avalon favourites you.tube site and see what they are acheiving with such guitars.
I'm not in any way involved with Avalon, other than as a customer. I just want the temptations removed from me
Good luck.[/i]
