Used Boss VF-1 24-Bit Multi-Effects Processor w/Power Supply
"The VF-1 24-Bit Multiple Effects Processor is BOSS' most powerful effects unit in history, offering reverb, delay, chorus, guitar and COSM-based effects derived from Roland's breakthrough VG-8 V-Guitar System, V-Studio workstations, DJ/Groove gear, and legendary BOSS effects gear."
According to Boss, this is their best multi-fx unit yet. Be the judge of that! This can be rackmounted, half a space. If you've got other Roland half space rack gear, you can fit them together to take a full space. This is a hi-fi 24 bit FX processor, not just for guitar! Looks great in the studio.
The VF-1 is in decent shape. It's got some rack rash, to be expected. Also, a little screen scratching, but only surface level. Won't affect visibility. This thing is a forgotten gem. Check it out for yourself.
