Ruby Amp PCB

From the vendor

The Ruby Amp from Five Cats Pedals is an LM386 based guitar amplifier board. It is an enhanced version of the previous Little Gem Amp designed by Runoffgroove. The main improvements of the Ruby Amp vs the Little Gem are new the input buffer, a volume control, and an updated Gain potentiometer. The board mounts vertically from the pots and fits in a 1590B perfectly – but you could put it in any box you wanted!

These tiny little amp’s can drive some surprisingly big speaker cabs! You can wire it to run from a 9v battery or the usual negative center 9v mains (we suggest the mains!).

You’ll get a full colour build guide with your purchase, but please remember you are buying JUST THE BOARD and you have to source your own components.
