I'm seriously considering one of these. My rig consists of an SVP-Pro to Rmx 850 to SVT610hlf. Currently I play in an alt-country/roots rock band but am considering another foray into the metal genre. This unit will work in mono, or so I've read. I'd love to hear from anyone who uses this unit or has used this unit. Basically, talk me out of this if it is a waste of money. I'm looking for a powerful,unique sound that punches through without sounding out of place.
