The rundown
What it is
The Darkglass Kaamos is a multi-effects pedal for bass that combines a distortion section with an octave-down generator. It was designed with bassist and producer Amos Heller, and it borrows the distortion character of the Alpha Omicron pedal. It has a dedicated sub-octave output, a choice of series or parallel routing, and an effects loop you can relocate to one of six points.
What it sounds like
MusicRadar's reviewer found the octave sounds excellent and described the drive as warm and amp-like. The same reviewer called the circuit design clever and felt it gave the pedal extra flexibility. The only tonal complaint was that the Tone control could offer more range.
Skip it if
Skip it if you only want a simple, single-purpose drive, since this is a large and feature-packed unit. MusicRadar's reviewer also wished the Tone control had more to offer.
Where it goes in your chain
As a distortion and octave-down pedal it generally belongs early in the signal chain, ahead of the amp. The movable effects loop lets you decide where other pedals sit relative to the dirt, and the parallel option lets you handle the low octave separately.
Highlights
- Distortion and lower-octave effects in a single unit
- Separate output for the sub-octave signal
- Routing can run in series or in parallel
- Built-in effects loop that can be set in six different spots
- Runs on 9V DC at 400 mA, center-negative
Best for
Bass players who want distortion and an octave-down effect in one box, with flexible routing for their other pedals.
