Boss GX-10

It is a compact version of the GX-100 that delivers.
If you play a lot of different genres and have a need of few effects but don't want to get a pedal for every stuff, this thing is loaded with Boss's legendary effects. There isn't a ton of amps simulations but what it has is good. The A.I.R.D. amps feel alive, if you’re serious about your tone and want a pedal that can keep up with your Metal chops, the GX-10 is a no-brainer.
Boss GX-10 proves itself as a robust build and reliable companion for guitarists. It is a versatile tool for any modern player and a worthy investment for those seeking a powerful all-in-one solution.

I have been playing guitar for more than 10 years and while I haven't used many effects, I do have some experience with classic pedals like wah-wah and distortion.
I bought the Boss GX-10 immediately after it came out but wanted to play around with it before actually posting a review.
At this point, these are my thoughts:
PROS:
1) The variety of sounds you can get out of it is remarkable.
2) The quality of the sounds is great.
3) I love the fact I can simply use my headphones to practice later without bothering my neighbours.
4) The option to use it as an interface is definitely good to have.
5) BOSS offers software that allows you to customise your sound more easily than on the device itself.
6) Solid build quality.
7) Small form-factor that packs so much.

CONS:
1) It may be difficult for new users of this type of devices to find their way in the interface. It's not that complicated but it may take you more time than simply dialing a few knobs on an actual pedal. That's why I recommend using the device with the software provided by BOSS so as to configure your preset more easily.
2) The wah/volume pedal works but do not expect an experience as smooth as the one with a dedicated such pedal. Of course, I did not have this expectation but thought it was important to mention it.

All in all, I would recommend this any day of the week. I guess that after a few months the convenient touchscreen will be enough for me to configure the sound I want more easily.

Out of the box the GX-10 sounds much better than my Headrush MX-5 with many really great pre-sets. The user interface however is not as good as the MX-5 and you really need to run the patch editor on a PC/Mac to be able to work easily. Annoying lag with the patch editing software on iPhone and Mac and harder (than Headrush) to organise patches, though of course Headrush doesn't have a PC editor so it needs to be better. The tones of the GX-10 make it a better machine overall, though...
