What's different about Aion FX kits?

Professional enclosures

The enclosures are drilled, powdercoated and printed by Disaster Area Designs in North Carolina.

Aion FX Kits - Enclosures

Top-mounted jacks

All kits use top-mounted input, output and DC jacks so they take up the least amount of pedalboard space (even less than a smaller 1590B enclosure with side jacks). They are all PCB-mounted on their own board, separate from the main PCB, for ease of assembly.

Wire assemblies

You can leave your wire stripper in the toolbox. All kits come with wire assemblies that are already cut to length, so they just need to be soldered to the board and plugged in. This makes wiring simple and foolproof, as well as making it very easy to disassemble the circuit for troubleshooting.

Premium footswitches

These switches have the longest rated life (50,000 cycles) of any 3PDT footswitch, and they also have much lower actuation force and switch travel than the others. They also have gold-plated contacts and solder lugs for maximum conductivity and corrosion resistance.

Exclusive footswitch dress nut

I designed these myself and had them custom-manufactured. They’re made of nickel-plated brass, so they match most of the rest of the hardware. They serve no functional purpose other than to make your pedal look awesome and stand out.
