Well I've had the Spider II 112 for 3 days and here is my unproffessional first time user opinion. Remember take this with a grain of salt as I have only been playing for 3 months. The music I like are AC DC, Metallica, 54-40, Stones, Tragically Hip, and especially Pink Floyd, so you know the sound I'm after.
First time user opinion, I don't like it all that much. I find it rather hard to find the sound I like, to play the songs I like. Blues (red) sounds almost the same as clean (green). Blues (green) is when it starts to get muddy and distorted and goes up from there. I've tried to play Back in Black in Crunch (green) and that's the closest I can find. I haven't been able to find a good sound for Enter Sandman yet but I'm still playing with it.
I know there are lots of settings to try and that's what I'm trying to do, play a little and turn the dials. You can turn off the auto effects with a movement of the drive dial and start trying to get the tone you want.
I took it over to a freinds house on the first day and he use to be in a band and knows what he likes and doesn't like also. He says it has good sound to a point but the effects could be better. We hooked it up to his Korg ToneWorks and that's when it really started to sound good.
In my opinion the Cube 30 I looked at had better, cleaner effects, but the Spider sure looks nice. I'm not saying the Cube 30 is better quality, just cleaner. I think for the heavy metal, muddy, high distortion crowd this would be a great amp.
If any one else who has this amp could give me some tips on settings for some of my favorite artists it would sure be appreciated.
Now I'm off to get a Toneworks.
