Little Gem

For better compatibility with effects driving the Little Gem, a FET buffer can be added. Both the Little Gem Mk II (seen below) and Ruby schematics include a simple buffer design. No further circuit modifications are necessary, however the input capacitor value of the amp may need to be adjusted to taste.

Listen to it!
