Designed originally for use with the Coles 4038 as a super-clean low noise unit, after extensive field tests in UK, Norway and France, we've found it sounds exceptional with ANY microphone including the classic Neumann U 87, perhaps because: We use extra-low noise valves with NO solid state impurities in the audio path, plus VERY special Sowter in and out transformers Input impedance is higher than usual to preserve clarity and can be tailored to individual mics with the Hi/Lo and Pad switches Incredibly musical and progressive saturation for distortion lovers when overdriven and by employing the fine and coarse attenuators Controls include Gain, from 40 to 75 dB, switched, HPF to reduce "proximity effect" and "Air" to add that extra clarity. Carefully hand made and tested in Harlow, England
