The Six X Five Hundred is a one channel transformer coupled Microphone Preamplifier and Passive 2 Band Pultec Equalizer.
It's an all discrete design based upon the great 990 amplifier.The Equalizer is our take on the magical classic Pultec design. It's got 12db boost of the creamiest high end you've ever heard and the most punchy low end heard the 21th Century.
The Sound can be described as "Fast" "Punchy" and "In ya face". The 6X-500 fits in all 500 series compatible power supplys.
