I use my Origin 50 as a platform for my OD pedal. Its pretty clean without the pedal. I compared the Origin to my JTM45 with pedal and sold the 45. I'm hoping the SV will give me more amp sustain and distortion at band volumes. I'm probably still gonna use an OD pedal. For the last 10 years I owned many Marshall NMV amps and used an attenuator. But that's behind me now. OD pedal all the way.
