Oh yeah. No more loud fan noise from the XLS. The BH420's fan is quiet Also, this will save some weight, too Lots of eq-ing capabilities (bass + 4-band semi-parametric mids + treble, plus Enhance and Tone - though these make it a bit too dry and clickety for my liking) - yet it's great flat, I think that's where it'll stay. I think I'll keep the SVP-BSP (can never know when I'll need it, the distortion/fuzz channel and the blend can be nice and useful sometimes), but the Crown will be going! So, that's about it.
