With 2 watts, a volume potentiometer plus a gain trim
potentiometer mounted right on the PCB, you can go from clean to
crunchy with the twist of a small screwdriver. Dial in your personal
tone then set it.

As an analog voiced circuit, the amp has warm tube tones with the
gain providing control over the amount of crunch desired. The SD-
2W delivers powerful volume with less noise. From clean tone to
heavy distortion you can rely on SD-2W to create the best sound
you could ever imagine!

Applying the BTL circuit could generate higher output (2.5 W) than
the other similar products (less than 1 W). LED, Head Phone Jack
can be installed without any additional parts. Trimmer controls the
gain in a low frequency range, allows you can control Clean and
Heavy drive sound. The Power on/off push/pull switch volume and
the SMT (Surface Mount Technology) take up very little space to
make installation easy.
