The Korg ToneWorks 105OD Classic Overdrive is an overdrive pedal, and the first release in Korg's Spirit Animal series. Like other pedals in the overdrive family, it pushes the front end of an amp for added grit and sustain, and it adds a boost function on top of its core drive circuit1.
What it does
The 105OD works as a conventional overdrive with an added boost function, giving a player two gain-related tools in one box: the drive itself for pushing an amp or fattening a clean tone, and the boost for lifting a solo or a riff above the mix1.
Josh Scott and Nick of JHS Pedals, writing about Korg's vintage ToneWorks DSP pedals, described one character quirk of the unit's sound:
"it has a weird aliasing harmonic that's slightly irritating as the note decays, but just like certain irritating family members, it's kind of endearing."1
That kind of digital-era artifact is worth knowing about if you are comparing the 105OD with analog overdrives, where notes fade without the same harmonic byproduct.
The enclosure
The pedal's graphic is a talking point in itself. As Josh Scott and Nick put it:
"You'll notice it has a spider on it. Or maybe an ant? It has four legs."
