From the vendor
Clone board of the Spaceman Effects Sputnik IIb. This is the latest version of the now famous Sputnik line of fuzz boxes that were produced by Spaceman. The circuit has been tweaked to add additional tonal variations, as well as allowing for the input transformer to be switched out, if so desired. We were a bit sad to see that a Drift diode reversing switch was not adopted by the Spaceman crew, but we made sure it's still there as well. All in all... it's still one of our all time fav fuzz boxes. Get in, buckle up, and hang on! A wild tonal ride is always guaranteed!
