The buffer/booster circuit is the same from the Reverberator, a very popular and great sounding clean boost that\'s clean and loud.

It\'s op-amp based and built out of really nice components like WIMA film caps, Nichicon Muse caps, 1% metal film resistors, NE5532P op-amp, Neutrick jacks, Alpha clear shaft pot. The real time level meter is a neat vintage style 10 segment bar graph LED.

They\'re high impedance in, low impedance out, can do a clean boost of around 20dB at 9VDC, safe up to 24VDC.
