Good call. What's your current board have on it, and what's going in the Bloop?
I'm currently running into a One Control Crimson Red Bass Preamp > Mesa Subway + (with BF-2 Flanger in the Effects Loop) > Power Amp (typically either the effects return on my MarkBass Nano Mark or my AG-500 112 combo). I adore the CRB - it is my instant reggae sound which works for a lot of my main band's songs, but it is a one-trick pony, and I have toyed with the idea using the Bloop to cut out the highs with a stomp, but also to connect a secondary board (Fuzz/Delay) to a guitar amp as well. Either way, the utility is a nice thing to have on tap.

This thing KILLS. I definitely notice a difference in tone. It cleans up all the muddiness in my signal at the cw end of the dial, but I'm able to bring some of that undefined low end back in to shake my whole room while still having enough clarity to discern faster & more complex runs. The extra bottom end it gives to thinner sounding pedals is also nothing short of tremendous, but still never a hint of muddiness! I'm very surprised and excited for my future using the Bloop as a utility, it even sounds great just by itself!
