BAE 1023L 500 Series Mic Preamp and EQ

The BAE 1023L is a 500 Series adaptation of the highly popular 1023 mic preamp and EQ, which itself takes inspiration from the 1073.
The BAE 1023L uses the same mic/line preamps the 1073 but expands on the original design by adding significantly more frequencies to choose from in the mid-range and high bands with the mid bell curve capable of overlapping both low and high shelf bands opening up a wide range of tonal shaping options.
The 1023L uses Carnhill (St Ives) transformers and is entirely handwired in the US and houses the preamp and EQ into 3 5oo Series slots.
