Best Boss idea EVER!
Mateusz Trojak, 22.12.2017
I wanted to limit number of my pedals and also a weight of my pedalboard. I also wanted a good looper with good MIDi implementation to control my Strymon Timeline and Marshall JVM205H.
I already have a G-Lab GSC-3 but: it is very heavy, big and MIDI implementation is so so.

Initially I wanted to buy Boss ES-5 but after reading good reviews of MS-3 I pulled a trigger. Basically I replaced my 4 Boss pedals: EQ-7, CS-3, BD-2, CE-5 with this unit and I'm more than happy! No noise, quite good noise gate, easy programming (even easier with computer editor), low power consumption (using mooer micro power to power MS-3 and 9 other pedals!).

I'm long time Line 6 user (POD XT, X3, HD300, FX100, HD500X) and drive pedals was always a weakest point of this products. This is not true with Boss!. I'm really shocked how good drives sound! I can easily replace my Mesa Flux Drive and Ibanez TS. Boss, well done!

Great product which can be used as stand alone pedal board, or a brain of more complicated setup.

Its OK
Tim6819, 23.07.2017
I ordered this to replace a complicated pedal board set up, because I was sick of tap dancing. The concept of being able to use Boss effects, plus switch in loops containing my other pedals and programming it so one touch of a pedal could select all manner of different sounds appealed.
Problem 1: The loops are 'joined' in the signal path, so you can't have loop1 (a POG) at one end of the signal path and then a few of the MS3 effects and then loop2 (a delay) at the end... the loops had to be together, so its not very flexible. Problem 2: Its really not very nice to program. I'm sure plugging it into a PC and using the editor makes it easier but trying to set this up in a rehearsal room with the band was an utter pain, and was too long winded. I got massively frustrated and gave up with it.

Its nicely built, and the effects inside are very good - although the rotary sounds are nowhere near as nice as the Boss RT-20 which is ironic. Its quiet in operation and the switches feel robust yet positive.

To be honest, I've sent mine back - it didn't do what I wanted it to do and the operating system was a deal breaker for me.

To sum up - some great sounds, some great ideas but just not quite flexible enough.
