Ya, in the "low end" I'm digging Fathead II plus.. something else. Last weekend it was a LDC (e300?). Blending those two signals I doubt I'll need any EQ. The condenser is bright and really cuts, the ribbon is dark and heavy. Studio owner suggested I try the Fathead instead of the R121.. I was kind of shocked by that, but I loved the results.
This was my first outing with the Fathead II, I have a Cascade Victor which I also like quite well on a guitar cab.
