The Jackson Audio Prism Purple combines a boost, preamp, EQ and buffer in a single pedal, giving you the tools to explore different facets of your guitar’s sound. Whether you’re looking for more presence, a more pronounced attack or a more powerful signal without altering your original tone, its three boost circuits let you choose the response that suits your playing style.

The ‘Color’ mode features a vintage-style treble boost, with emphasised highs and rich harmonics. ‘Amp’ favours a response closer to that of a valve amp pushed to its limits, whilst ‘Trans’ boosts the signal level whilst retaining its natural tone. The Pre-Gain selector then lets you choose between a wide dynamic range, a slight crunch for rhythm parts, or more pronounced distortion for solos.

The active EQ also allows you to adjust the treble and bass within a range of ±15 dB. The Tone and Body controls operate independently: you can therefore brighten your tone or give it more body without one affecting the other. This is particularly useful when you change guitars, amps or set-ups and want to quickly find the right tonal balance.

Placed at the start of your signal chain, the Prism Purple responds naturally to your guitar’s pickups and volume control. Its high-current output buffer helps preserve signal clarity through a busy pedalboard or long cables. Relay bypass, adjustable indicators and 18 V internal operation round off this pedal, designed to give you greater freedom in shaping your sound.
