Custom AMT Mi-Si Preamp for Fishman Pickup




Now available only from AMT is a rechargeable batteryfree Mi-Si preamp that's been specially modified to obtain improved sound from Fishman's passive Nashville bridge insert reso pickup.  This unique charge amplifier preamp design substantially reduces the pickup's non-linear distortion and provides an active, buffered output which minimizes effects of cable capacitance while also providing better signal level matching between the pickup and Aura pedal.
