Awesome pedal

Elwyn 03.09.2023

Previously had a Boss GP10. The Gm800 is literally night vs day in comparison. Great sounds, tracking is super and the unit is easy to use especially when linked to Boss Tone Studio. I’m having so much fun and creating some unique music.

A big step up from the old GR20/GK3 combo

fommof 11.02.2024

I've owned the GR20/GK3 in the past, TWICE.

The GM800/Gk5 combo has better tracking (NOT perfect, far from it, it's just the nature of the beast, triggering sounds via hex pups) and less glitches in general.

In my humble opinion, this has nothing to do with the Gk5 vs Gk3 debate as a hex pup, is just a hex pup, a passive component. It has to do with the fact that the GM800 is a computational beast in comparisson.

More that 1000 sounds available (and as always, not all are good), great customization, small size but it doesn't have a built in expression pedal which is good in terms of modularity and size, but bad because chances are you will need one and that means you have to pay for it.

Great PC editor via USB but a bit slow for my tastes, it gets the job done.

The front panel menu reminds me of digital devices 20 years ago and for me it's not intuitive either. So, thank God, the editor works.

Kudos to Boss for moving away from the 13pin cables, which to me were just a PITA in terms of reliability.

To update the firmware you need a USB flash drive, which begs the question, why Boss didn't just gave this device the capability to update the firmware via the USB cable.

Das Jahr 2000 hat angerufen und will seinen USB Stick zurück

polanoid 21.12.2023

Firmware 1.0.3 ist nötig um das BOSS Tone Studio zu benutzen, auf dem Gerät ist nur 1.0.2 installiert (obwohl 1.0.3 vor einem halben Jahr veröffentlicht wurde) und das Update läuft (trotz vorhandener USB-Schnittstelle) über einen USB Flash Drive. Doof wenn man seine schon vor zehn Jahren entsorgt hat, mitgeliefert wird jedenfalls keiner. Schwaches Bild, ein Stern Abzug. Sound und Verarbeitung sind aber top!

Amazing sounds and customization.

I Me Me My 27.11.2023

Great tones, so many combinations.
Plenty of output options. Connects to PC with ease.
Waiting for more devices with high speed serial connection to create a family.
