Great Missenden

For sale is my Boss MS-3 Multi Effects Switcher (multi-effect pedal and loop switcher).

It is in absolute MINT condition and has velcro hook tape attached. Comes in the original box with all the original papers, rubber feet (unused), etc. Please see the photos.

I've also updated it to latest current firmware (1.08).

I bought it in April this year in a fit of lockdown GAS, but it's overkill for my needs and I need to recoup some of my costs, along with some other gear (e.g. MIDX-20, etc).

My take: It's built to legendary made-in-Japan Boss quality. It has an awesome collection of quality Boss effects built-in (apparently the same effects as GT100, and to my ear the same as is built-in to the Katana). 

It has three switchable true-bypass effects loops in which to put any effects of your choosing (e.g. your favourite drive or mod pedals). It takes expression and switch pedals and has a built-in noise gate & foot volume "block" that does not take up any "dsp blocks" as well as a global EQ, leaving you with 2x Fx blocks, 2x Mod blocks, a dedicated delay and another dedicated reverb block - all movable in the chain. Also has a built-in tuner.

It can also control any MIDI device via the built-in MIDI Out port (this is what I used it for primarily). I've also used it to control software plugins on my laptop (e.g. software loopers, plugins in DAW) via MIDI.

Any questions? Feel free to ask!
