PLETHORA X3 is your flexible collection of up to 127 mini boards within your pedalboard – just like the original PLETHORA X5. In comparison, the only hint of a compromise is 3 slots instead of 5, but you may well find that beneficial, as it takes up less precious real estate on your pedalboard! Rest assured that the sound quality and flexibility is every bit as hard rocking as PLETHORA X5.
