Line6 kb37, whats your take?

[sistamattix]

I have been recording demo's at home for about a year and a half with the line6 kb37, mainly for the guitar stuff and vocals. I really like the avalon pre amp model it has and a few of the guitar amp models. I still record bass through a cab and mic set up because I never liked the tone I was able to achieve with the kb37. Anybody else have any advice, comments or otherwise on this set up?

Thanks in advance.
