<p> Recently I built this on my Breadboard with the Motorola transistor & Resistor values from the original article, but the transistor was mis-biased & sounded pretty crappy! I recommend changing R1 to 560K ohms & R3 to 10K ohms to get the bias into focus? These two Resistors are the ones that make this tick, so if yours doesn’t quite sound right, these are the ones to fool with? I also recommend using a Low noise NPN Bipolar Transistor like BC108b or BC547b instead, it will not have the noise & hiss of the original transistor? Another recommended substitute is to use an ordinary 5K ohms Linear pot instead of the switched pot, as they are not as common as they were at the time the article was written. And forget the dotted line in the schematic that connects to the power, this is for the switched pot? Pro Tip: if you have a Breadboard, then that’s the best way to sort out the details of what Resistor value works best? </p> The Germanium diode in the Fu…tag:www.cigarboxnation.com,2021-08-21:2592684:Comment:36577692021-08-21T22:19:06.715ZBrianQ.https://www.cigarboxnation.com/profile/BrianQ
<p><span style="font-size: 14pt;">The Germanium diode in the Fuzz box is on the rare side, depending on where you are, so I suggest using 1n34a & 1n270 Germanium diodes, as they are more common & easier to find</span></p>
