Buzzaround-Alike

Hello new and old friends! On this day AD, we have some exciting news. I, Miro have been dubbed as thee second-in-rank-admin to help Mark around on the blog. Many of you already know me from various post threads ๐Ÿ™‚ Anyway. I’ve started to draw layouts some time ago and we thought we might give a go for these too. My layouts look a bit different  and there is a reason for that. I have been using Linux as my only operating system for last 8 years and the software version Mark uses, well, doesn’t work too well on Linux/Java. Comments are open, so please let us know if you think this is a bad move ๐Ÿ™‚

As a tryout for Miro’s layouts, we have Mictester’s Burns Buzzaround-Alike. Description from Mictester:

The legendary Burns Buzzaround was a slightly unusual germanium fuzz that achieved its (undeserved) reputation for two reasons – some great guitarists used them, and they are virtually unobtainable. The original consisted of two stages – a two-transistor amplifier and a distortion stage that could have both the amount of signal sent to it and the bias point adjusted by external controls. The third control was a crude tone control which fed the output. Originally, the output was unbuffered, and the leads and amplifier following would load the unit, and the top end would be rolled off, and often the tone control would have little effect. 


The first stage in the sound-alike is just a high input impedance op-amp gain stage. You may wish to increase the gain by increasing the value of the feedback resistor, but it sounds pretty good as shown. In the original, the first stage didn’t really have much effect on the sound – it just amplified it enough to drive the following stage into conduction. 


The heart of the beast is the germanium transistor stage. Apart from using an NPN transistor, this remains true to the original (why screw up a classic?), and still gives a wide range of sounds from the thin toppy fuzz beloved of sixties bands through to gated spluttery farts, with smooth warm distortion sounds in between!


The final stage is just a buffer – it isolates the tone circuit from the outside world, and allows a full range of control from muffled to glass-shattering!
