Had a rat to fix with a chip issue, so bought a pile these to sort it and stock going forward. The LM308 chip used in classic Rat pedals. Plus a socket so if you build one you can swap out easily, there are other options but this is the classic. Additionally, if you are not so good at soldering, the socket means you don't need to worry about overheating the chip. If you are swapping one into a Rat that has the chip soldered directly to the board, socketing it is a good idea.

Use add to basket and request a total to get correct postage on multiple items.

Overseas bidders check in advance about postage. If you find it last minute and bid, that's cool, but message and and give me time to check postage before paying, so I can actually find out and invoice correctly.
