OK, the pedal is an early block logo with LED but the circuit board is covered with foam and I can't see the pots. There is a serial number where the battery goes and its 4-151304. Does anybody know what year this number relates to, maybe 1984?........
No, not that sort of date!
My friends got a mustard coloured Distortion + with a block logo and he thinks its late 1970's but he's not sure. Is there any way of finding out exactly when it was made (like by any serial numbers, etc)? Thanks......
