I'm thinking that a clean electric sound will be better for strumming than my infamous Boss AC-2. Perhaps a little compression might be in order? Occasionally I accompany my singing with a strummed or Travis picked part. I have either a Diamond Compressor or a Boss CS-3. Since they are both quiet different (see what I did there) from each other, which do you suppose would be more suited to what I have in mind? The CS-3 had a setting in the manual that is suggested for chording, FWIW.
