I have a UrgeI bass (32" scale) and have played a UrgeII. These are nice basses (esp if you can get a used on eon EBAY), that play extremely well, this statement comes w/ a caveat...
I find them to be compromises of both tones and types (remember they were designed w/ stu hamm who is really a lead bassist, and the basses have that type of midrangy, cutting tone). My UrgeI is really a hybrid of J & P type tones, its not true to either but it does have very useable tones and an amazingly playable neck and feel. The UrgeII had better bottom end over the UrgeI, and similar to the UrgeI the tones aren't really a true P nor J, however they are very useful. The necks on these basses play extremely well and the bodys are downsized and lightweight. So you do loose out on some bottom end in comparison to say a fender P bass
The preamps on both are versatile and your able to dial in some dent sounds. One the UrgeI, the pre is very electronic sounding (its a modified Kubicki pre), the UrgeII was more fender-ish. I say if you have a chance to play them, try em out. They are an interesting hybrid bass...not really P and not really J, but useful none the less.
