I recently got a Benjolin, its a weird old box of frogs isn't it!
Its a nice looking White and Gold one from Meta Audio Labs
Lots of cross modulation going on, Ochd is modulating the benjolin and the benjolin is modulating Ochd, Sloths is also modulating the Benjolin and bringing the reverb'd parts in and out on the SSF Vortices.
Its certainly interesting to play with!
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
