The CP-34 Head Boom is a distortion pedal from Caline, a guitar effects pedal described by RockBoard's PedalPedia as "designed to provide a vintage distortion sound"1. It is an analog circuit, aimed at players who want a classic-flavored distortion rather than a modern high-gain voice, and it sits alongside Caline's other distortion designs such as the Head Room Vintage Distortion and the Rock Face Distortion1.
Power and circuit
The CP-34 runs on an analog circuit and takes a 9V DC supply with a center negative plug, drawing 20 mA1. That current draw is low enough for almost any pedalboard power supply, though like most compact pedals it is worth running from an isolated output rather than a daisy chain with digital pedals.
Where it sits in Caline's range
Caline builds a wide lineup of distortion and overdrive pedals, and the CP-34's vintage-leaning voicing is one voice among several1:
| Pedal | General character |
|---|---|
| CP-34 Head Boom | Vintage distortion1 |
| Head Room Vintage Distortion | Vintage distortion |
| Rock Face Distortion | Distortion |
| CP-77 Bounty Hunter Heavy Metal | High-gain heavy metal distortion |
| CP-27 White British Distortion | Distortion |
For a broader look at the effect type, see the Distortion Pedals page, or Caline's overdrive side, including the American Sound and English Man, on the Overdrive Pedals page.
