Toneshaping Pedal with Preamp
Buffer, Boost, and Dual Active EQ Jackson Audio’s flagship pedal, the ‘Prism’, is a serious tone-shaping beast, capable of boosting, buffering and sculpting the tone of your dreams. Much like the in the manner in which optical prisms break white light down, Jackson Audio’s ‘Prism’ breaks down your guitars organic tone and enables you to rebuild it in a unique fashion.
This comes in particularly handy for the guitarists out their who perhaps need to widely vary their tone, as per the requirements of the song. With the ‘Prism’, you can lighten the load on your pedal board, and do away with some pedals, the ‘Prism’ is a serious multi-tool. The tone shaping begins with a hugely responsive active EQ duo, which enables you to shape your guitars high/low frequencies independently. After which, the ‘Prism’ directs the signal through the preamp and boost section, which hosts 3 unique boost circuits – transparent/clean, tube amp-style drive, and a vibrant silicon treble booster.
Lastly, at the end of the ‘Prism’s signal path, is a tone-saving high current buffer which alleviates signal loss caused by long cables and busy boards. Jackson Audio’s ‘Prism’, is one of the best ways to transform your guitars tone, give it a try and bear witness to some stunning results!

‘MOSFET’ Circuit

3 levels of intensityInside the ‘Prism’ is 3 separate boost/preamp circuits to utilise. Each showcasing a unique voice and breakup behaviour. The transparent clean boost retains your guitars natural tone, but gives more room to hit your amp harder.
The ‘MOSFET’ circuit churns out a tube-amp style saturated boost for a beefy crunch, soaked in harmonics. A vibrant treble booster circuit shines at the scooped guitar crunch, something very reminiscent of Brian May’s sound. Once paired with the pre-gain switch, which offers 3 increasing levels of intensity, a whole wealth of vivacious tones are just waiting to be discovered!
Dual Active EQ

15dBs cut/boostThe dual active EQ inside the ‘Prism’, offers precision control over the high/low frequencies of your guitars tone. The ‘Body’ and ‘Tone’ controls behave independently from each other, allowing you to boost and cut the low frequencies, whilst the high frequencies remain unaffected.
The guys at Jackson Audio recommend placing the ‘Prism’ at the start of your chain, enabling you to swiftly adjust the characteristics/tone of your entire rig. With a whopping 15dBs of cut/boost on each control, it’s possible to make subtle changes, and big changes, extremely swiftly.
