The one's that I've had-
-MXR Bass Chorus- It was ok.
-Tech 21 Bass Boost Chorus- Wish I still had that one. No longer in production.
-TCE Corona- Nice chorus. Versatile with the TonePrints. A bit too subtle for me, but you might dig it.
-Source Audio Gemini- Nice chorus. Similar versatility with the Neuro app. Same issue as the TCE.
-Iron Ether Polytope- Wish I still had this one. Very lush. Not that simple, but outstanding.
-Strymon Mobius- It's the king of digital modulation. Way more than what ya' probably need, but it's XLNT!
-Boss MD-200- It's a sweet multi-modulation pedal. Almost as good as the Mobius. Would be good if you wanted multiple modulations.
The one's I've still got-
-Boss CEB-3- It's a Boss pedal, so it works. For being on the lower end of the spectrum, it's a damn good chorus pedal.
-Strymon Ola- A bit of a dark horse. Definitely not common on bass boards. Too bad, it's a solid chorus pedal on bass. The MIX knob is winner. This is a really good digital chorus pedal.
-Neunaber Inspire- Kind of versatile, kind of expensive, kind of uninspiring.
The one's I'm considering now-
-Seymour Duncan Catalina- Seems to be a super solid performer on bass. Watched Patrick Hunter's demo. I like the added Dynamic Expression feature. Found some used ones, probably gonna give one a go.
-Analogman Chorus- Can now be ordered with top jacks and a Deep setting for bass. Always gets stellar reviews. Expensive, but could be worth it.
-Foxgear Ballade- just found out these guys existed yesterday, LOL! Allegedly, the Ballade was developed with the help of Tim Lefebvre. It's analog, with a mix knob, top jacks, and it's only $99. There's no demos at all, but it ticks all my boxes and it's only $99! I'll probably buy one just because it's $99, and I might get the flanger, too.
