P-BASS Sounds on a J-BASS? The New Sadowsky MID BOOST PREAMP | A/B Comparison Demo with Lars Lehmann

In this in-depth demo from the Sadowsky Germany headquarters, ambassador Lars Lehmann puts the brand-new Sadowsky Mid Boost Preamp to the test, showcasing a powerful upgrade designed for MetroLine, MetroExpress and even non-Sadowsky basses. Personally introduced by Roger Sadowsky as the latest evolution of the company’s renowned drop-in electronics, this new assembly expands the classic Sadowsky 2-band system with a dedicated mid boost switch at 500 Hz. Long associated with the Will Lee and Single Cut models and previously too complex to retrofit, the mid circuit is now available as an easy-to-install solution for players seeking more P-Bass-like punch from their instrument, with a flick of a switch. At its core, the preamp retains the unmistakable Sadowsky layout: master volume, pickup blend, Vintage Tone Control (VTC) that operates passively even in active mode, and stacked bass and treble controls. The new mini toggle engages a 10 dB boost at 500 Hz, delivering focused low-mid power ideal for rock, blues and modern fingerstyle tones. Powered by a 9V battery with an impressive 870-hour lifespan, the pre-wired, solderless design makes installation straightforward, whether as a control plate assembly for J-style basses or as a harness for instruments without a plate. In this demo, a MetroExpress Vintage J serves as the test platform, allowing direct A/B comparisons before and after the upgrade. Through slap grooves, fingerstyle passages and isolated pickup examples, Lars demonstrates how the mid boost transforms the familiar J-style character into a more assertive, P-style-like voice to make your bass as versatile as it gets. The added 500 Hz push brings definition, body and mix-cutting clarity without sacrificing the transparent hi-fi nature Sadowsky is known for. For players looking to elevate their MetroExpress, refine their MetroLine or inject new versatility into any compatible bass, the Sadowsky Mid Boost Preamp stands out as a significant tonal upgrade rooted in decades of design expertise. 🔔 Don’t forget to subscribe and hit the notification bell so you never miss an update!
