MOOER MICRO PREAMPs are sonically accurate digital recreations of the preamp sections of popular tube amplifiers. We have developed these by directly analyzing real tube amplifiers using a brand new technology to capture their sound, dynamics and response. Each Micro Preamp comes complete with dual channels, integrated speaker cabinet simulation, and dual-operating modes to suit the needs of all users. • High quality dual channel preamp • Independent 3 band EQ, Gain and Volume controls for each channel • Speaker cabinet simulation on/off • 2 different modes for footswitch operation.
