Based on the Spaceman Effects Sputnik
From the vendor
For the purists that prefer the simplicity of the first Spaceman Sputnik, here you go. The only mod that we've provided is the moving the DRIFT function from a toggle to a footswitch, as with the Sputnik II (DEFX Laika Fuzz). It is more convenient for "on the fly" switching. Doesn't have the complex tone section of the second unit, but don't count it out. It can provide more than it's fair share of fuzzy goodness, or outright chaos. Some folks claim to enjoy the voicing of the first Sputnik over the second. Hey... who are we to stand in the way of love!
