Hi, I'd like to know which Line 6 multi effect would be the best fit for my Spider IV 30 considering that I'm just a basement player. I thought about the FBV3, the MK II shortboard and the M13, but it looks that some aren't totally compatible with the amp. I also looked for a Boss ME-80, but I really liked the idea to use the FBV pedal plug on the amp while having the possibility to use some stomp box on the more traditional way. Thanks for the advices!
