I have a deluxe Jazz right now with a John East Retro J Deluxe preamp. It’s a nice preamp. But, my other two jazzes have Audere Preamps with 4 band tone controls and I just prefer them so much over the John East. Anyone wanna trade me straight up? This is what I want. Jazz 4B T Chrome This is what I have. John East - J Retro Deluxe - Best Bass Gear I realize the John East is more than double the price. Call me crazy, I don’t really care. I’ll still straight up trade.
