We are changing the MN3007 Panasonic delay chip in the analog man bichorus pedal. If you have a normal sound but no chorusing sound, then it could be this chip. The chip sockets will have a cutaway on one side which should be similar on the chip, or there will be a dot on the corner of the chip on the socket cutaway side. But it’s best to take a picture of the chip before you remove it to make sure you put the new one in the same way.
