EBS Unichorus clipping IEMs???

[Dazlexic101]

I love my EBS Unichorus. I really do but for some reason I've noticed it starts clipping in my IEMs but not my front of house mix.
While the effect is engaged I lose volume as the chorus dips down but as it goes back up it clips.
Weird thing is that it mainly happens on my A, D, G strings all around the neck.
I've got the blue a black version, not the later green and black 'studio' version.
Both knobs set to 10 o'clock.
Any advice?
For reference my signal chain is Fender Elite Jazz V -> Korg Pitchblack Tuner -> MXR M87 Bass Compressor -> EHX Nano Big Muff Bass -> EBS Unichorus -> Joyo Time Magic Delay -> Behringer BDI21 -> Ampeg PF800
