So I recently got a Deluxe Reverb RI, based on some great advice from everyone here. It's a great amp and it performed really well at my gig a couple of weekends ago. But I found myself just browsing through the GC website, and saw that they had a used Vibrolux in great condition at a pretty nice price. I went to see it at the store, and it came home with me: It has a touch more power than the DRRI, and 2 ten inch Celestion speakers instead of the single 12. The amp is in great condition, and even still has the specs/features card on top. The reverb and tremolo work on both channels, and sounds really good. I'm inclined to believe that this may have been a demo or something, based on the condition, and its location along side of all the other new amps. Either way, I think it is totally worth $799. Looking forward to bringing it to practice this week.
