This kit is based on the EA(Electronics Austrailia)
Tremolo. It's a great vintage sounding trem like
you would find on an old tube amp. Straight
forward - just "speed" and "depth". An internal
trimpot lets you set the volume level. The
amplitude modulation is done with transistors, so
unlike most opto-coupler based trems, you don't
get an "on/off" sound on slower speed settings
and there is much less current draw. It's also a
lot easier to build.[/img]
