500 series preamp module featuring custom transformers, XRELmode for color options and a front-facing combo jack for XLR and DI input

The 501+ Preamp is the blue crème de la crème of 500 series preamps, designed to deliver both pristine transparency and bold character on demand. At lower and medium gain levels, it provides a clean, open response that captures every nuance of your source. Push it harder, and the 501+ adds a rich, colorful saturation that brings depth and personality to vocals, instruments, and more.

Built around a permalloy transformer and the legendary 2520 operational amplifier, the 501+ combines classic analog warmth with modern reliability. A convenient front-panel combo connector allows quick connection of microphones via low-impedance XLR or instruments in high-impedance DI mode, making it versatile for both studio and live applications.

Compact yet powerful, the 501+ Preamp is an essential addition for any producer, engineer, or musician seeking professional-grade tone shaping in a 500 series format.
