Best All-Round: BAGSMART Organizer
This is what I end up using most often, and I think this is the best choice for most ‘404 owners. If you’re looking for a bag that’s affordable, fits the AC adapter, offers decent protection, has some extra storage, is compact and highly functional… look no further.
For more protection…
Avoid: Analog Pulse Case
Sadly, this case doesn’t really fit the MKII. The interior pocket is nearly useless because anything inside can flop out. If you don’t mind your AC adapter rubbing up against your SP, and having it all flop around a bit while inside the case, then go for it, I guess. Tested, but not recommended.
For a hard case that actually fits…
Best Mod: RAIACE Hard Case
If you don’t mind making a little modification, this is probably the best performing protection that’s still usable day-to-day. The mods aren’t hard (watch the video above), but even with the mod, this case won’t fit the AC adapter.
For the MOST protection…
Light modification required
Most protection: THULE Legend
If you want serious protection, buy this case and cut the included foam to fit the SP-404MKII. The downsides are that it’s bulky and the carrying handle is weird (but it’ll probably last forever). The AC adapter is a squeeze for this one—you have to get creative!
It took me awhile to understand why Decksavers even existed, but then my partner bought me one and now I have them for all my grooveboxes. They’re super durable and their design and fit is just perfect when you’re throwing something this expensive into a backpack. Of course, they also prevent dust from collecting on the studio shelf, but it’s more the physical button, screen & knob protection that I love.
