Well, after occasionally considering Weber Beam Blockers for many years I thought I'd give one a try. I use a HRD lV for the outdoor stuff and put the Beam Blocker in there. Yesterday we did an outdoor show and I had a significant loss of bottom end. I had to crank the bass knob to about 10 and it didn't do much to increase bottom end. My question is... Anybody else experience this loss of bass when using a Beam Blocker? I can't really replicate the experience here in my tiny townhome cause it would need to be LOUD. I've experimented with the signal chain (the same pedals I've used for years) but don't hear a problem there. Gave the tubes the tap test and let them run for a few hours. They look very healthy in a dark room. We have another outdoor show coming up and I'm tempted to remove the Beam Blocker before then. Experiences anybody?? Thanks!
