First off, I love good hard rock to high gain sounds playing classic 70's and 80's rock. So I bought a Scumback H75, 65 watt speaker this week and replaced a c90 Black Shadow speaker in a Peavey 112SX open backed cabinet I have been playing and gigging with for about a year thinking it would improve things dramatically. I am using a Crate V30 head and I play an Edwards LP with an awesome Suhr Aldrich humucker in the bridge into this rig. I thought I would get this oh wow feeling when I installed the Scumback but I'm not. It is no better sounding than the C90 speaker in this setup. It is about the same. So what am I overlooking? the cabinet sucks? It is particle board so is this my problem? I bought this Peavey 112SX 1x12 cheapo convertible cab several years ago when I started gigging out to use instead of my Mesa 2x12 Recto cab because it is so damn heavy. Will I get the oh wow thing going on if I get a Lopoline, Avatar, or some other higher quality 1x12 cab either closed or open backed?
