THE EXTERMINATOR’S NIGHTMARE
RESISTORS: Yageo & Xicon brand metal film & no value substitution at all.
CAPACITORS: HQ Panasonic solid polymers, low ESR electros, CDE silver mica + film and ceramic caps.
OpAmp: Motorola LM308AN
For this build, I only installed D1 & D2 clippers. I will include the 2nd set of clippers, Smoothness trimmer & Clipper selector switch in my next Helios build.
This project just works & it sounds great! The RAT lives on!
Aion-designed PCBs are extremely well-thought-of & with simple & clear instructions, making pedal building fun, easy & very rewarding.
Thanks to Kevin for an excellent re-design of this popular pedal based on the Pro Co RAT2 Distortion.
Please share your build experience on Helios. Thanks for reading.
