BuddytheReow
Breadboard Baker
This is another one of BuddytheReow's "originally" designed circuits and is more involved than my last build, the Heavy Devi. The heart of the circuit is a Bazz Fuss which does the clipping. You can read about this most latest version here. I need to update the daughterboard layout since I realized I made the layout incorrect. I will update that shortly.
Anyways, first is a PREGAIN control which throws some input signal to ground and the tone doesn't change in either direction. Then a BMP input stage to act as a boost. The "GAIN" pot on the BMP is the STARVE control here and gives that velcro sound when the signal is barely going into the Bazz Fuss stage. This then goes into the Bazz Fuss with selectable diodes and a Bias control. The diodes range from a Schottky 1n5817 through a Blue LED in terms of voltage drop. I went boutique-y with this and used a MPSA13 as a diode just to say I did it fancy, haha. The larger the voltage drop (LED side of things) the more "open" this sounds. Think less compression and clipping here. Higher voltage drops gives a more distortion vibe and smaller voltage drops give a more fuzz/buzz vibe. This then goes into an active Baxandall tone stack and then a volume control to output.
It's a glorified Bazz Fuss.
Boxing this up was the most time consuming, but I had the most fun here. My workbench looks like I spilled sprinkles everywhere. I think my offboard wiring is getting better compared to some of my other stripboard builds. I said better, it's not great yet.
I'm not 100% sure on the knobs or the enclosure art. I decided to box this up after really playing through it for about a week and decided I was happy with it.
Buddy's Breadboard and Circuit Design Notes
I’ll have to see what all the FUSS is about ;) One note on the jumper wires, that bottom-right cell, it will be empty long before the others. I‘ve been using bits of bus wire lately rather than buy more boxes of wires for just those sizes.
