The new ‘Blue Bottle’ Inductorized booster is in the pipe five by five and we’ll be ready to begin shipping very shortly. This little pedal is built on a custom blue circuit board and utilises a N.O.S. Sylvania ‘green-print’ 6021 pencil tube. These tubes were manufactured in Sylvania’s Emporium plant, Pennsylvania, U.S.A. in the 1980s and are a particularly good vintage, being exceptionally quiet and smooth sounding. Absolutely not to be missed if you’re seeking beautiful, warm, full-bodied mids for your ‘Strat’ or single coil equipped electric guitar!
