I built this Silicon Tonebender posted by mictester over on Freestompboxes. I used this layout. Everything worked the first try and it sounds good. I used BC109CN for transistors. These sounded good and have that metal can with a little tab mojo. I used a ceramic .1µf cap for the input cap and skipped the Fat switch.
The fuzz is so thick you can cut it with a knife. The tone control is useful. Everything cleans up well with volume control. Would I box it up? Heck yeah! This is a keeper.
No need for expensive hard to find Ge devices. I think I might have to get a few more of these metal cans just for their mojo. If I had any complaints I would say that the Gain control lacks range. You really can’t back this off to a mild fuzz. When the effect is on you know it.
This also gave me an opportunity to use some poor quality trimmers that I had lying around.
I used sockets to experiment with different transistors.
