Is it easier to get a blues sound of a rock-ish type amp or get a rock sound out of a blues-ish type amp.

Both being tube amp of course.

I was looking at either the Fender Hot Rod Deluxe or the Fender Blues Deluxe Reissue.

Blues amp.

i guess blues from a rock amp. Not sure though.

Rock on y'all!

Use something vintage that is used for both. Like a Marshall. Jimmy Page used a Marshall, and he got good bluesy and rockish tones.
The Blues Deluxe is a great amp.

You could also get an old style Marshall and nail them tones perfectly.
