I recently bought myself a Boss MS-3 and it’s a fantastic piece of kit. I will try and do a full review later, as I don’t think there’s one on Basschat, but initial impressions are really good:
116 different effects
50 banks of 4 patches each
every patch can consist of the following - 2 effects/2 modulation effects/1 delay effect/1 reverb effect/3 loops/noise supressor
easy UI both on screen and using the PC software editor
three loops for extra pedals means you could have your favourite or go to effects in loops and just use the onboard stuff for the more esoteric sounds
the ability to switch effects on or off within a patch in manual mode is fab
decent inbuilt tuner
true bypass if you want it
