MXR at their best

I am using this for 4 years now and never had any issues. I either run last or in a loop through my HA3500 with minimum settings as it can get really distinct. Both the flanger and chorus sound perfect.

Sound from the deepest seas

I don't know if I ever tried a better sounding chorus pedal on bass. I think it can eat some boutique pedals for breakfast! Bass and treble controls are great and sure are a better feature than the mix knob or something similar. It goes from subtle chorus to vibe and beyond. So, chorus is great, but flanger? IT is magnificent, a total mad mans creation! The moment I hit that button I instantly started to play 46&2 over and over, enjoying it more and more. Housing and knobs are great but I really think that MXR should get toggle switches in place of that white buttons and a more solid foot switch, something more soft and better quality like TC ones.

Versatile chorus

Good quality pedal. I especially like the crossover function which allows for a cleaner, less muddy bass chorus sound.

bass chorus/flanger.

been looking for a decent bass flanger for years that doesn't rip the tone of the bass to shreds since my old boss bf-2b packed in. this does the job nicely. well made, robust & versatile. nice chorus effects on it too but i haven't really gone down that road too far. crackin' little pedal if your looking for a sweet bass flanger.

Reasons to avoid

Toggle switches instead of white buttons might enhance the pedal's overall durability and tactile feel.
For users primarily seeking a dedicated chorus or flanger, the dual-functionality may seem more complex than needed.
