Purchased brand new and recently decommissioned from active service in a pro studio, this unmistakable fire-engine red box is widely hailed by top engineers and bassists as the ultimate tube DI ever made. Inspired by the legendary Ampeg B-15 amp, it pairs a high-voltage 6N1-P vacuum tube circuit with a massive custom Cinemag output transformer to deliver unbelievable warmth, punch, and depth.
