SUBSPACE TRANSMISSION
Subspace Transmission is a square wave fuzz with a recording and playback feature based on the ISD1820 voice recording chip. It can record up to 20 seconds and the playback can be repeated and pitched up or down. It's perfect for playing along to your riffs and coming up with new ideas, or why not make a short repeating loop and pitch it down for some sick drone sounds!
Please note that it can't be used to do overdubs because of the limitations of the chip and the repeat is not fluid. There's always a short delay between the repeats. But it's still pretty awesome what a 14 pin dip chip can do. :)
