So I'm selling one of the famous John East U-Retro Deluxe (with the passive tone control thingie) up for sale, with custom-cut Burlwood knobs, for $400 shipped. Never heard of the U-Retro (or it's cousin the J-retro)? Check out their webpage here. Still not convinced that this is the best preamp money can buy? The Dudepit's been selling these things for awhile, and there's a bunch of customer endorsements here The U-Retro Deluxe that I'm selling doesn't have the stock chrome stack-knobs, it has custom-cut Burl knobs so that it can look pretty on your custom high-end bass with the fancy-schmancy tops. If you'd rather have the chrome knobs, email me and we can work out a price deduction and I can tell ya where you can pick up the stock ones (cuz unfortunately I don't have 'em ) Follow this link for some pictures that I took. As always, feel free to email me with any questions, and I'll get back to you as soon as possible.
