Overview

These micro preamps are sonically accurate digital recreations of the preamp sections of popular tube amps. We have developed these by directly analyzing real tube amplifiers using a brand new technology to capture their sound, dynamics and response. Please ensure to use a clean _w power supply and a high quality power amp to get the best results. Each Micro Preamp comes complete with dual channels, integrated speaker cabinet simulation and dual operating modes to suit the needs of all users.
