The BJFE/Bearfoot Arctic White Fuzz is YAFF but certainly has been souped up and sounds great to me. I'm sure it will be as popular as Bjorn's other effects. Thanks to Matt for the schematic.
Info about the original:
Another favorite from the BJFe research program .... The Arctic White fuzz purrrs like a snow leopard at lower levels and attacks with full vintage growl when pushed ...... this is the most straight forward of the BearFoot fuzzes .... vintage in sound and feel with its own voice and personality.... and its a great recording fuzz as Bjorn wiped out the backround noise found in most fuzzes... 8-18v ... Volume Level - Fuzz Level and Tone control with just the right amount of treble control to match the Arctic to your little piece of the tundra .....and your Honey Bees new best friend.
