I got the Vintage 30 I ordered today. I had it shipped to work, so I brought my guitar and amp to give it a test run. As mentioned here, while I plan on upgrading all my cheap Celestions to Vintage 30s and GT12-75s eventually, I can't justify spending much money to do it right now (or a year and a half ago when I created that thread...), but when I saw I could use my credit card reward points to get a speaker, I jumped on it. I'm sure replacing 1 of the 4 speakers in my Marshall 4x12 won't make much difference in overall sound, but I figure it'll making recording quality a lot better if I'm just micing that speaker. Plus, once I'm comfortable spending money on music stuff again, I'll just need to grab a 1960 cab from Craigslist and just buy one more Vintage 30 to get a good X pattern going. Then, my 2x12 can get the extra GT12-75s. So far, my impressions on the Vintage 30 are pretty awesome! I haven't been able to crank it, since there's another business down the hall, but what I've heard I've loved! The first thing that I noticed was that my lows seemed kind of muddied, so I turned the bass down and turned up the treble. I already keep my mids pretty high, but just that change of bass and treble really brought out the sound. I'm guessing that Vintage 30s are better about getting good sound without the bass, since they're primarily for mids, so I'll just have to experiment with my EQ settings to account for that. I almost don't want to put it in my 4x12, since I'll probably only be able to hear it when it's mic'd and I'm using headphones to monitor. But if I got a 1x12 box to put it in, I'd only be able to use it with my Blackstar, and I really want to push it like it should be with a Marshall!
