This kit is based on the EA (Electronics Australia) Tremolo. It's a great vintage sounding trem like you would find on an old Blackface Fender Amp. 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.

Features all through-hole components, and full-sized panel mounted hardware.
