The Okko FX V.I.B. is a buffer pedal: a small circuit that sits between your guitar and the rest of the chain and keeps your signal strong over long cable runs and many pedals. What sets it apart from a straightforward buffer is that its input is adjustable. RockBoard's PedalPedia describes it as "a buffer circuit with adjustable input parameters," made for players who want a say in how their guitar's pickups meet the front end of the board1.
Controls
The V.I.B. carries two 6-position rotary switches, IMP and CAP, and they work together to shape what the buffer's input does to your tone1.
| Control | What it does |
|---|---|
| IMP | Sets the input impedance, from 10 Megaohms, described by RockBoard's PedalPedia as "super brilliant," down to 10 Kiloohms, described as classic "tone suck"1 |
| CAP | Changes the input capacitance, which affects the resonant peak of your pickups; the lowest setting adds no capacitance1 |
The IMP switch is the more unusual feature. Most buffers present one fixed input impedance; here you can sweep from a very high setting that keeps everything bright down to a low one that mimics the loading of old-school pedal chains. The CAP switch works on the other side of the same question: capacitance rolls off high end and shifts a pickup's resonant peak, and being able to set it means you can match the buffer to how your particular guitar sounds. Okko FX suggests players "will be surprised" how different the settings sound1.
Where it sits among other buffers
Plenty of buffers keep things simple, such as the JHS Pedals Little Black Buffer, the TC Electronic Bonafide Buffer or the Empress Effects Buffer. The V.I.B. belongs to the smaller group that treats the input stage as a tone control in its own right, closer in spirit to the Lehle Sunday Driver SW than to a set-and-forget unit1.
