I don’t often stack but I will hit a suhr eclipse with a greer lightspeed from time to time if I want the eclipse to sparkle a little more. (Lightspeed at the edge of breakup, eclipse for mid gain with a slight scoop and high gain with a mid bump.)
Right now a Snouse Black Box 2-> BD-2w -> Rat 2-> Hudson Broadcast. Still playing with the order. The Broadcast has a transformer that pushes it 24v so it hammers everything after it, so it’s the last in line.
I was using a SD-1 into the Snouse for a while and it was killer.
