Red channel on the DSL (OD1) has plenty of gain..no pedal needed, but then I have no solo channel from there without boosting from the loop which I do not like doing. With the 205 I can only assume that it's red channel has to have as much gain as the DSL...but then it has the separate master volume like an older 900 (21/2500).. should work fine. I will be curious to see how this stands up to my modded DSL 100 which to me is one of the best sounding Marshalls I ever heard...especially the red channel one...with the master volume up. No pedal required. I will be curious to see how it stands up to my DSL 100.
