b:righten

We’ve just completed a new batch of the b:righten dual VCF. For this run, we’ve shifted to a monochromatic panel design for a cleaner, more cohesive look. The circuit remains exactly the same as the original: a dual MS-20 style filter that can quickly go from smooth to wild. You can grab them now at www.bartinstruments.com. Thanks for the support!
