Used Groove Tubes The Brick microphone preamp in great condition delivers warm, punchy tube tone in a rugged, portable steel chassis. This single-channel Class-A design pairs a 12AX7 tube with a custom transformer for rich harmonic character, and offers XLR mic input plus 1/4" instrument input for direct recording. Front-panel gain and output controls make it easy to dial in everything from clean detail to vintage-style saturation.
