Boss SD-1, quite worn as shown. This has been upgraded with the Monte Allums GT mod. 

The mod adds two switches:

-One switch adds presence and gain (selects between a 2.2ohm and a 4.7 resistor)

-The other switch selects between Asymmetrical (Standard SD-1) clipping and Symmetrical (Tubescreamer style clipping)

-A 2N3440 Transistor has been added to the circuit

-Original LED replaced by a bright white one
