I was scanning consumer product recalls for my day job when I noticed several musical instrument related recalls in the listings. There were more – audio amplifiers and such – and I’ve only linked a few here that caught my eye that are instrument related.

[602] Super Buffer Update

Date: February 14th, 2010 | Comments : none | Categories: DIY.

The AMZ Super Buffer was never meant to be used with a footswitch, but was intended as a line driver that was always left on and therefore did not need the pulldown resistor on the output. The R7 output pulldown resistor was left off the original pcb layout but it has been requested numerous times, so I finally got around to revising the layout to provide a place for it on the etched board.

The links in the article now have the revised artwork. The old pcb etch and parts placement are still available for those who need them.
