I use a couple Tech 21 Sansamp Character series pedals for my bass and electric guitar and they work great as ‘amp-in-a-pedal’ type boxes. I think they have some less specialized versions that might be more versatile for using with both, but I got away with using my guitar through the VT Bass model before also getting the Liverpool (Vox model). The Liverpool pedal is good enough that I don’t really use my handwired Vox AC15 anymore (it’s just soo loud). Maybe not what you’re looking for but I dig them.
