"This synth sounds (and looks) incredible. It's in beautiful shape with real wood sides and has recently been professionally upgraded to the latest by . The KIWI upgrade adds a plethora of power to the 3p and on top of this, the owner of SynthSpa also did a Jupiter 8 Filter mod, that replaces 12 capacitors that power the filters the same as the Jupiter 8. The result is a very deep, rich, silky sounding synthesizer.

SynthSpa did this upgrade because the JX3p's internal components are very similar to the Jupiter, and when comparing this to a Jupiter 8 side by side after this upgrade, they sound pretty much identical. Part of the key also resides in the Kiwi upgrade that allows the user to detune the oscillators just like the older VCO's. It has two independent ADSR envelopes (one for amp other for filter), two LFO's, more LFO options, can control the speed of the analog chorus, unison mode, arpeggiator, sequencer, etc."
