An Eden Metro running an Eden 115XL extension cabinet.
The Metro would have been plenty for a four-string, but those low Ds and Cs are asking a lot out of Twin Reverb sized cabinet. Adding the 115 turned it from an upright to a concert grand. Not boomy, but the lows were just filled out wonderfully. I don't run a lot of EQ, typically a little boost in the deep end, flat middle and a slight cut in the highs.
I was amazed HOW MUCH better it sounded to me than a Super RedHead on top of a Son of Bertha, and it's a LOT louder. Both on casters, footswitch for the two Metro channels, mute, etc.
And it sounds good to the rest of the band, which always helps !
