Narrow box TS-808. Very early! From the Analog man website: The TS-808 and its generation have small square metal on/off touch-buttons. Almost all TS-808’s sound great. There were some TS-808s made in the 1979 period, mostly for other than USA markets, that came in a narrower box. These have a bottom plate that unscrews to change the battery like an MXR pedal, no plastic battery cover. This narrow TS-808 had a different circuit. It uses two 1458 chips which are the 1st version of the low-tech dual op-amp. Also the LEVEL knob on these is labeled BALANCE and the external 9V power jack is on the side next to the input jack. *Non-original baseplate screws
