Homebrew Frostbite Flanger with 18v power supply. Fantastic pure analog flanger, the best made out there now in my opinion whether considering rack or pedal. Just not getting used much on my latest stuff and could use the money. Never gigged, not "as-new" but pretty close.
$219 shipped in the lower USA 48.
Stock pic, but mine looks pretty much the same...
Here's a vid of it on guitar, it's every bit as nuts on bass too... http://www.youtube.com/watch?v=Q7nCzXvVY3g
Would consider a partial trade for some cash and a Danelectro Spring King. Otherwise cash only please.
