I'm just back from playing the WAV4, NXT4, and CR4 at my local music store. These are all out of the box, no setup and the standard strings. The WAV4 sounded like a cheap EB now matter how I changed the the settings on it and my AI Ten2 amp. The NXT4 sounded much better, more "resonant" and just felt better in my hands than the WAV4. The CR4...WOW! If you can afford the $2500 or so price tag, is amazing. I was able to quickly dial in a UB sound that was very pleasing to my ears. If I had the $$, IMHO the CR4 would be the best to go with.
Thanks. That is the kind of info I am longing to get. I want to know how much is it worth to make the leap from NXT4 to CRM4 giving the steep price. I find myself wanting more tone flexibility than the one available on the NXT as I find myself always turning the tone knob all the way towards the left.
