I took it but ended up using the Swollen Pickle because we did a line check and I didn't really have time to mess with things. The band is kind of slow and sludgy w/ 1 guitar so I'm thinking the SP might actually be the better choice, it kind of blurs the line between guitar and bass and makes everything sound huge. I use a Darkglass M900, usually the VMT is active with this band. The RP might work better with the B3k setting.
I actually used the RP on guitar & bass on some recordings though, it sounds great in a mix. I used an SG into the RP into a 5150 emulation plugin set crunchy.
What kind of band are you using it with on Thurs?
