DON’T JUST FUZZ IT, FUSE IT
POWER MOD: 18V mod via the charge pump circuit
RESISTORS: Yageo brand metal film / no resistor value substitution on the project.
CAPACITORS: Panasonic solid polymers, low ESR electros, CDE silver mica caps & one standard 2.2uF e-lytic.
OP AMPS: AION specified ICs
CLIP MODS: AION stock mods
As usual, I installed Small Bear’s light plate.
EQUIPMENTS: Marshall JVM 205H head / Marshall 1960A cab / IBANEZ S5470Q guitar. ESP Korean-made JH-600 model guitar with EMG pickups. Only Fusion is connected.
TEST RESULTS: I haven’t used nor heard a Suhr or Riot distortion yet so I can’t compare this unit to it but I’m very pleased with the overall sound & tonal character of this distortion. The Presence mod via the trimpot clearly & substantially change the highs of the pedal. The circuit is fairly devoid of electronic interference. Lots of Volume to spare too!
AION-designed PCBs are extremely well-thought-of & with simple & clear instructions, making pedal building fun & easy.
Kudos to Kevin & the AION tech staff for an excellent re-design of this pedal based on the classic Suhr / Riot distortion!
Please share your build experience on the Fusion Distortion. Thanks for reading.
