From the vendor
I am mad at danelectro!!!! I used to really like their stuff But not only that they pretty much doubled their prices for their instrument without making them better But a few years ago, Stephen Ridinger, the boss of the Company that owns Danelectro donated at least 10K$ to a cause, aiming to ban gay marriage in California. That made me sad since it made it hard for me to enjoy their stuff since I still kinda like their stuff Enough ranting More PCB stuff This PCB is kinda based on the Breakdown by said brand wich is again very much based on a old drive circuit (sorry I am to lazy to research the name of it right now) The original has a 6 position rotary switch for the amount of breakup That is very fun to do but kinda shit for DIY I changed the switch to a potentiometer wich not only gives you finer control over the breakup, but also makes building the thing easier and cheaper But you also have the option to build it with a (8 point!!!) rotary switch I kinda fucked up so the positions are a bit weird but let`s ignore that....
Oh and the entire thing is something between boost and overdrive or whatever Almost forgot that
