My impressions ultil now:
Finally found the right EQ.
many criticized me for getting the 115 instead of the 410, saying that I would only get mud from it ("d'ya play raggae?" asked me the seller). The fact is: the sound I'm getting isn't muddy at all, The V8 is roaring as never, and, when it fails to cut, I just use the MAGICBUTTON (the mids, on the thumb). I'm very impressed with this cab. You can't really feel it in the store.
Up to now, the combination (RH450 + WCA 115) suits me. Maybe in the near future I'll be getting a 210 (in the store the 115 sounded really nice combined with a Hartke 210, and they didn't have the WCA 211).
Tried to get a clip, but recording from a cab is much more difficult than direct, so, maybe I'll keep trying.
Last saturday I've put the rig through a really heavy test (although I used my friend's 411, not the 115): faced an Orange 200W tube head with a 412 cab. My set did very good (with a little help from my MAGCIBUTTON friend). We played VERYLOUD. Yuri ruined 2 sets of drumsticks. Definitelly aproved, tonewise and loudwise.
