I bought a used 5:50 and it had a noise and I've decided I'll bring it back tomorrow. I thought I'd be smart and get a 5:50 head [add $350] but what I really want is a LSC head [add another $800 on top of the $350] so I play currently at home and volume is not an issue.I don't really want to spend the extra for the LSC head but my equipment buying addiction is telling me that I have room on a credit card .Now what I need to know from players with experience with both amps, is the difference worth the money for someone who plays at home , what's going to make me say "WoW" this is worth it, I've been playing the 5:50 for 2 weeks and I like it and let's face it I don't need more but the want factor is too strong . So are the tone possibilities so much more with the LSC that I should jump in the deep end . I have 2 2x12 cabs one with 2 g12t75 and one with 2 200 watt Ev's Some feedback would be great tonite because the store is 130 miles round trip away from here.Thanks
