At one point I had considered selling my RK1 to help fund a Roadster. The cleans are definately better.
What stopped me was the fact that I probably take more advantage of the Progressive linkage then I do of the cleans, and the cleans are still good on the RK1.
My setup is
CH1 four 6L6's in Clean
CH2 two EL34 in Brit
CH3 two EL34 in Vintage
CH4 all power tubes (two EL34 and and four 6L6) in brit.
I really like using the EL34.
But I got this RoadKing on a steal.
If I were saving some scratch to buy a new amp, I would go with the Roadster.
