Best overall: Radial Engineering Clean signal

Buy on Amazon

The radial engineering clean signal is long-lasting, rigid and fits well with your daily usage like a dream. The active pickups on your bass should be producing a line-level signal that can just pass through the di and be fine. It lets you plug a guitar or bass into the mic input of a mixer without the tone being screwed up. They naturally smooth out the transients that sometimes sound harsh on piezos, and they can handle huge amounts of signal before distorting, so they're well suited for the Godin Multiac series of guitars.

These boxes are compact and simple, they sound great with no audible noise, and they're solid as a rock. This preserves the sound quality very well when running with 300ft of cable. It should work with both passive and active pickup systems that use batteries. It is perfect go-to for all di applications.
