Boss GX-100 Guitar Effects Processor

I've tried several multi-effect units up to the 550 CHF price range. I still have the Hotone Ampero (which I find fantastic for its price), but for live situations, I needed something larger that is more robust and has more effects. I have found the BOSS-GX to be the best choice after a lot of research and testing.

Pros:
-- Fantastic sound, even the factory presets are very usable
--Top of the line Boss effects (I especially needed a usable intelligent harmonizer)
--Assignability of various functions to various foot switches is outstanding
--Very usable size for the switches and the expression pedal
--Color touch screen makes adjustments much simpler

Cons:

-Display set-up still a bit old-school (until one gets the hang of it, after that no problem)
-No unbalanced output (but most venues would have a DI box; aI ordered one and it fits into the (the separately purchasable) case of this effect unit
--If you are into having a large number of different cabs with the built-in amps, that you may want to upload more IRs than what's available as factory preset. (I just went with the default tab for each amp, and found them very good).

Overall, after testing several other models/brands in depth, this is the one that I am keeping and I am very happy with it.
