Specimen 432
Studio-4
A 3-watt battery-powered bass practice combo that weighs one kilogram.
Why it matters
It runs on a rechargeable 9V cell, so it works without a mains socket, and Bluetooth streaming lets you play along with backing tracks from a phone. A three-band EQ, headphone out and line-in cover quiet practice, and an extension speaker out means you can add a cabinet later. Shown at NAMM 2025 at $75.
