That's a great combo amp with a wide variety of tones available just in the amp. But it depnds on what kind of guitar you are using & specifically what kind of bluesy rock you are rerferring to.

Check out this demo that shows how to dial it in for a wide variety of options from clean to grit to crunch.

[quote=Mayo Mayone]I´m using BOSS pedals like bluesdrive delay and reverb as well.

I'm not sure you even need a pedal unless there is a specific song or artist you are trying to emulate. Hope that helps!
