I am selling my Markbass Super Synth. It is in very good condition and of course functions just perfectly. One of the greatest Synth pedals of all times! You need to be aware that would probably need an adapter for the power supply, which is of course included but has a german/middle european connectors.
So you don't need to buy a new power supply, just an adapter for a few bucks (amazon e.g. has them for 3-5 bucks), Of course the pedal itself doesn't care, it functions everywhere just fine as you will know.
I would be interested in a sell for 170GBP o.n.o (insured shipping is included) or for a part trade with Markbass Tube Marker and/or Markbass Super Booster.
Best,
Danesh
