- DIY simple guitar effect.
Just a simple demonstration. Trying out breadboarded LPB1 that I described on barbarach.com/...
Video's sound quality does not do it justice, since my phone's mic is not great but hopefully it still comes across all right.
I like to start building pedals too
glad I clicked on another one of yours my man - I tried doing a pedalboard runthrough of a version of the Stratoblaster...pretty sure I nailed it, but, then.....I realized that I needed to be able to do the offboard wiring, specifically the input/output jizzacks.....thanks for the info!!
I'm glad you found it useful :)
This is my first pedal and it’s not boosting my guitar but dampening the sound, any ideas why?
hi, I'm not sure if you figured it out already. I can only guess - some of the general steps to do are: check if you have connected everything correctly, check if you're using correct resistor values. The voltage divider at the input is very important, I think I had too high resistor values once, even though the ratio was correct, and base current was throwing the ratio off and I could barely keep the transistor on. If you figure it out, or if you tried different things and it's still not working please report back and we can continue troubleshooting ;)
Bro this good
i tried your schematic with a 2N2222A transistor instead and 4300 + 430 ohms for R1 and R3 and i got a huge signal in my amps. so i guess i should use the correct components, may also be the potentiometer 500k is not enough...
Thanks for the tutorial, i'll try again later
Hey there. The issue is in R1 and R3. 2n2222A should work just fine. From what you're saying, the effect is working, but you did not get the boost? The reason 430K and 43K are chosen (and you can use 470K and 47K which are more common values) is to try keeping the input impedance as high as possible but still being able to keep transistor working. This is still low impedance and causes some "tone suck" and with such small values for R1 and R3 you're using that effect will be even more pronounced. Lower the input impedance lower your output signal essentially. Anyway, maybe try higher values for R1 and R3, even 100K and 10K will be an improvement.
Build yourself a test box it will be easier than connecting all those jacks etc. there is a vid on my page if you need help
I'll have a look :) I had built a test box a while back. It just did not do it for me at the time, it did not lower the noise and interference as much as I wanted it, and it just wasn't compatible with the way I like doing things. Maybe I should revisit that idea. Thanks :)
@@BarbarachBC Yeah it won't lower the noise if the circuit is on a breadboard, its only designed to make the connections easier. It might lower the noise a bit if you use insulated input/output jacks. Anyhow heres my vid it might help: ua-cam.com/video/l5nUPE81Lm0/v-deo.html
