Kustom GrooveBass 1200 vs 1300....

[mini455]

Does anyone have any info on differences between these 2 heads? SOUNDWISE that is, the look change is obvious, sound and features is the topic here. Thanx

I'm curious about this one too, as I have the 1200 myself (and I love it!). Kustom's website doesn't really seem to tell anything about the differences.
