Just got it home this afternoon, let it warm up for a little over an hour (it's quite cold here today), and put it through its paces. I also got two new cords for my effects loop so I don't have to use the cheapos that my son partially broke. All the reverb types are cool and usable, with the possible exception of reverse. It's fun to fiddle with for a second or two and that's it. I don't have trained ears so I don't know how much the spring sounds like a spring tank or the plate like a plate. Actually, those are the two settings I probably like the best. The spring setting makes me think I could at least sound similar to Dick Dale anyway.
The modulated setting is very subtle except when the level is cranked. It adds sort of a washy-ness to the reverb. The halo setting is their shimmer mode. Once again, it's subtle but I get where some have called it an "angels singing backup" kind of sound.
The liveliness knob basically controls the high end of the reverbs. I found that particularly useful when switching between single coils and humbuckers. I thought that might be a "set it and forget it" knob, but I'm thinking it's the one I'll be using the most.
The only negative I can see thus far is the paint job makes the reverb settings hard to read. I suppose once I get familiar with the settings in their various positions it won't be as big of a deal. Thankfully I still don't need glasses, so that helps.
Overall my initial impression is very positive. I ran through all my licks where I really wanted reverb before and it made me want to play more. I mainly played with clean settings. I'll try it later to see how it sounds with distortion. The halo and modulated settings could either sound really cool or really busy in that scenario. Guess I'll find out! I'm definitely going to see how a touch of reverb will help rhythm playing, then I'll kick in my delay for solos. I'm grinning just thinking about it.
