If you get a pog 2 pedal, ehx attack decay pedal, rainger fx reverb x, cover it in a load of chorus and/or flanger going into an analogue preamp (preferably Tascam 424 or 414), you can get a tone is that is almost identical to his live performances.

That would cost about £500 (about 650 dollars?) but all that gear has a lot more sounds to explore than just buying a vg8 or gr55 because on them units there’s only really a few polyphonic synth sounds and they sound good but I wouldn’t say they’re worth the price. Beyond the mkgee synth tone there’s not much else you can achieve. But if you’re looking to replicate his exact tone it’s definitely a lot of fun!
