    Adding a transistor selector switch to a RangeFinder

    I want to mod my rangefinder by adding a switch (or array) to go between different transistors. Is there a best-practice method for wiring something like this up? I was hoping a 3pdt on/on would work, but I'm also super new to this. Thanks!

    SOLVED Tone Vendor MKII Low Volume

    Hey all, I built a Tone Vendor MKII, and while a little bright, the bigger issue is that the output volume is too low. The volume pot on full gets me just under unity gain. before I mess with the 470r and 8.2k resistors to get more volume I figured I'd ask if this circuit is naturally quite or...

    Carbon Black with 2N3904s?

    I suspect the answer is that I can't use them, but figured I'd ask. I have a bunch of 200+/- HFE 2N3904 transistors lying around and was going to use them in a Carbon Black Fuzz instead of the 2N3903's required. My understanding is 2N3903s have half the HFE, so would my 2N3904s be too much for...

    SOLVED [Solved] Son of a Ben feels high-passed

    [Picking up where another thread left off] I built a Son of a Ben and it all seems to be working correctly except it is incredibly bright. I need to have the bass on full and the treble between 0-3 to get a usable tone out of it. It feels/sounds like there is a significant high-pass filter on...

    Sandspur Output Volume

    Hey! I built a Sandspur and love the tone, but I need to have the volume cranked to get the right increase in volume. I understand this is typical of some vintage fuzz circuits, but are there any mods I could do to increase the overall output volume? Thanks in advance for any ideas!

    Son Of a Ben no signal

    Hey! I built a Son of a Ben preamp and it won't pass any sound when engaged. It passes signal in bypass and Q1-3 are biased to 4-5V each. Any idea where I should check for bad connections? I feel like if I can bias the transistors, the majority of the circuit is good to go, but I'm an...
