I have a swamp sequencer for sale, it was built by lowgain electronics, comes with boat, rack ears, and wall wart power (can give you a molex cable too if you would prefer to attach it to your psd)
it is in great condition and works as it should.
Located in Buffalo, NY
$1250 shipped in the US, will ship out of state at buyers expense.
Will also consider trade options, I have two swamps and decided something else would be more useful.
