Chandler's Little Devil Series is a line of vintage-inspired 500 Series modules with discrete circuitry and transformer I/O.

The Little Devil Pre Amp is a discrete, Class-A mic preamp with direct input. It's relatively flat, wide bandwidth response can be curtailed and colored with the variable bias/feedback control, as well as running the input gain hotter and dialing back the output control. Additionally, the front panel offers a fixed high-pass filter, a "bright" switch, selectable input impedance, and 48V phantom power. Can be run with mic or line signals, as well as hi-Z instrument signals.
