Diode, not transistor.

It's most likely some variation on a common source amplifier, much like a fetzer valve, an Echoplex preamp, a JHS Minibomb (aka Escobedo Duende JFET), a Tillman preamp, etc.

The voicing of the circuit is going to depend on the filtering and the clipping, and I can't comment on those without ever having used the circuit. But you could compare the above circuits, listen to samples on the internet, and start experimenting on the breadboard.
