Which SED Winged=C= for a Roadster?

[jhguitar1]

I am going to buy a quad of SED Winged =C= for my Roadster head. I noticed there is a choice of early, average, or late distortion. Which one works best with the Roadster?

Thanks

You should use average. If still in doubt, call Doug at Dougstubes and he can hook you up. He uses Groove Tubes rating system. Average being 4-7 which is what is called for in using Groove Tubes in a boogie.
