The 1023L — based on the classic 1023 — takes the preamp and EQ from the 1073 and expands upon it with significantly more frequency options in the high and mid sections, even allowing users to play the mid bell curve directly against the high and low shelves where they overlap.
The 1023L is completely hand-wired using Carnhill (St. Ives) transformers. It has the exact same mic/line preamp as the 1073, but with significantly more frequencies in the mid and high sections.
Aside from simply offering more frequency settings to play with, these expanded EQ sections also allow you to play the mid bell curve directly against the high and low shelves where they overlap. This capability opens the tone shaping possibilities in very interesting and musical ways.
