BOSS RC-600 + RC-300 Rhythms + Assign

I found the BOSS RC-600 not a great fit for how I use loops. (update for this check other videos) Rhythms are great quality Dont have enough ability to assign different rhythms to trigger pedals like BOSS FS-6. Only 4 option for variations which is a shame when you have so many other patterns in the rhythm section. You can only trigger variations (4 total) and drums kits and volume For volume control you'll need expression pedal
