2 Introduction & Usage

INTRODUCTION

The Chroma Parametric Boost is a clone of the BOSS

compact stompboxes released in 1977. (The other two were the OD-1 OverDrive, which is available as

the

Parhelion

project, and the PH-1 Phaser.) It was discontinued in 1981, and due to its extreme rarity,

today it routinely sells for $500 or more on eBay.

The original SP-1 is a parametric equalizer with only two knobs. The frequency knob adjusts the boosted

frequency between 500Hz and 5 kHz, and the balance (or mix) knob adjusts the dry-to-wet signal ratio.

The gain and Q are fixed. Unlike some other parametric equalizers, it only boosts frequencies-it doesn't

have the ability to cut. Its function is very similar to a fixed wah, and you can hear a wah-like effect if you

turn the Spectrum knob while a signal is being passed.

The updated version of the Chroma adds one new feature: the output volume has been increased and it

now includes a volume knob. This way, the output volume can be precisely trimmed for unity gain (which

is inexact in the original Spectrum depending on where the Balance control is set), or it can be used as

a booster with an adjustable frequency emphasis. When used in front of another overdrive pedal or to

overdrive an amplifier, you can get some really unique drive tones that wouldn't otherwise be attainable.

USAGE

The Chroma has three controls:

• Spectrum sets the frequency of the boost.

• Balance pans between the dry signal and wet signal, acting as a sort of depth control.

• Volume sets the overall output of the effect. The original unit was fixed at unity gain and did not

have a volume control.
