Here's another option if you need to keep the size of your board under control - think about swapping out one or both for a Line6 HX One. I don't even have a board of my own, but I'm finding all sorts of little jobs I might be able to nail using this thing.
I'm not an effects heavy, but I want to sometimes be able to do this 'n that. The HX One isn't as complex as something like an HX Stomp, which would certainly overwhelm me if I tried to do much of anything with one of those. What's great about this HX One is that it will only do one pedal effect at a time... but it will be a lot of different things, both for bass and also guitar (I noodle at home).
If you're not familiar with this little box, I recommend that you look at a rundown of what it does. You can do a LOT of different drives, lots of different fuzzes - useful fuzzes - and then there's other stuff; modulation, octave effects, yaddah-yaddah. Instead of needing to go shopping for this pedal for one song and that pedal for another, I can save myself from needing to make that investment and having to manage all that gear by using this.
Bonus points: it sounds fantastic.
Bonus-Bonus points: it's easy to tweak.
