I love the sound of Rotos or Hi Beams on my 4003, but since that's a sound I don't have any use for live, the Ric wasn't getting any use except at home. I put the ECB80 40-95 set of D'Addario Chromes on it a few days ago, and I must say it's a pairing that works really well. Tight, growly, and fat when you need it. I have tried heavier flats, but haven't been very happy with them on the Ric. The lighter set seems to work better for some reason. Gonna take the Ric to my next practice.
