    Distortion Pedal Redux

    Hi AG. I started from scratch. I don’t know why it worked this time. I think I may have had a short. I will post my new numbers soon. I am not 100% confident that all is perfect, but I was getting sound, so that’s a good sign

    I got them here I got it going without diodes. Next, I will do the diodes and report back Chironal 100pcs TL081 TL081CP IC JFET Input Amplifiers DIP-8 https://www.amazon.ca/dp/B07FFRMWTL/ref=cm_sw_r_cp_api_glt_i_KYTHN0RV7M3HNNB40B15?_encoding=UTF8&psc=1

    Putting this thread in hold. I need to check my wiring. Will report back.

    Distortion Pedal Redux

    So, now that I successfully built a distortion pedal circuit, with the help of people here, I decided to try something else. You will recall that I initially started with the attached schematic. Along the way, we made the following adjustments: The voltage divider circuit was substituted with...

    You're right. I should,d have been clearer. I am working from the two schematics you just put up in your last post- which is what I was working from last time.

    Now that we have this circuit working, I am going to rebuild it from scratch; only because I was modifying it along the way, as we adjusted the circuit, and, as a consequence, it was not as tidy as I would have liked. Before I do the rebuild, I just want to make double sure that I am working...

    Thanks AG. In terms of my question about the sequence of the wiring, I'd like to take it out of the context of building a stompbox, for now ( I understand what you are saying about wires acting as antennas if far apart). But what I am really trying to understand, is whether not connecting the...

    Also, the circuit calls for 10K tone pot. I only have 5 Ks or 20Ks. any advice?

    Yes, I do. This is great progress ( for me anyway), and for you guys for being patient teachers :-) I just finished installing C3 and the 270R resistor, Before I install the 10K Tone pot, I have the following important question: I have uploaded a graphic that you will need to refer to, to know...

    Hey guys: I have attached a sound file with the sound of the guitar, now that the diodes are in play. I used the same Roland cube amp, but this time I used a Fender Squier Telecaster guitar. This is not an expensive guitar. But I wanted to use a cheaper guitar to see what it sounds like. The...

    Thanks AG. Is the change supposed to be really noticeable when you work the pot, or is it more nuanced?

    Here is the way I am suggesting you look at the pot.

    More progress. I installed the diodes and the distortion sounds a lot better. However, the only part of the circuit that does not seem to be working as intended is the 500K Gain pot that comes after the C31 100pF capacitor and before R46 (1K) resistor. If you imagine the pots prongs facing...

    Leading to my next question. I am under the impression that the choice of filtering, by way of capacitors, impacts high pass and low pass frequencies. If that's true, I assume we can achieve more high frequencies by changing capacitor values? If so, through OHMs law, does that affect a complete...

    Here is a short clip[ as to what the circuit sounds like: I used a Fender road worn Brad Paisley telecaster ( a nice guitar), through the aforementioned Roland Micro Cube guitar amp. I had the Roland set on the Clean setting, with very very little volume and no gain (on the actual Roland amp)...

    Thanks Bertus. So, if they are almost the same, the ear test may be best. I will probably go with the IN4148 on this particular circuit, but when I get to breadboarding, it will be interesting to experiment with all of them, including LEDs. Thanks for the chart!

    AG....I am not sure I follow what you are trying to tell me,. But this is what I think you're saying. If I built in such a switch and flipped the diodes on, the sound would not be as loud, but the color and nature of the distortion will change (for the better I assume). If the switch by...

    I am thinking that perhaps the previous builds may have worked too. I have always used the orange amp to test as it is so small and convenient. I never thought to suspect it as being an issue. My apologies. The good news is that it works!!! To continue on, should I follow the original...
