Hi, lo and band pass filters with Q and drive controls. Great on the bass for those funky autowah type moments but also nice on the guitar. I also used it on rhodes and clavinet type keyboards to great effect.
They retail for about £65, I'll take £30 for it.
Grabbed it from the studio tonight James, I'll call you tomorrow to arrange getting it to you.
