RESISTORS: Xicon brand metal film / no resistor value substitution on this project.
CAPACITORS: Solid polymers, low ESR electros, CDE silver mica cap on C1. HQ box caps used.
OP AMPS: AION specified ICs
MODS: Ross + AION ‘Attack’ toggle switch mod. I’ll install the ‘Attack’ pot once I find a right angle one.
EQUIPMENTS: Fender MetalHead & matching Fender MetalHead 4×12 cab / IBANEZ S5470Q guitar. PRS SE Korean-made Tremonti model single cut guitar. Only Aurora is connected.
TEST RESULTS: I haven’t heard nor used a Ross Compressor but I A/B’d this unit to my original 2-knob Keeley Compressor & sure enough, as I expected, Aurora does a better job than the latter and has more functionality too! I also noticed than i’m able to turn the Sustain knob to the full position with very minimal noise under normal Level setting and at stage level amp volume.
AION-designed PCBs are extremely well-thought-of & with simple & clear build instructions, making pedal building fun & easy.
Kudos to Kevin for an excellent re-design of this pedal based on the classic Ross Compressor, Dyna Comp & some Keeley mod!
Please share your build experience on the Aurora Compressor. Thanks!
