G-Storm's replications are top-notch, IMHO. I'm quite familiar with the sound of both the Jupiter-6 VCF (mine is sitting about 5 feet to my left) and the ARP 4012 VCF from the original ARP 2600 versions (loads of experience with those), and they pretty much nail the sound of the originals while adding a few extra bonuses such as dual inputs and much smaller sizes than quite a few of the other replications. Noting that you had the Jove in there was a big key in opting for that change, freeing up that extra chunk of space.
