I've had the Line 6 Spidervalve MKI and a Line 6 spiderjam for years now, using the FBV Express mkii as my sole pedal. I'm starting to play alot more, with potential to play some gigs (nothing paid or major atm, although possible on the horizon)... wondering if the FBV shortboard MKII is still a worthwhile upgrade from the FBV Express? BtW I found a reasonably cheap used one online
