    Just When I Thought it was Going to Be Easy

    Thanks AG. Will put it on my list of things to try. I just finished building the circuit using the flawed op amp, and it works perfectly; including LED, DC barrel and stomp switch. Next, I will be putting it in a box. I also just discovered the joys of working with solid wire, rather than...

    Is there any way of using two different op amps in this circuit?

    Thanks @AG as I have many more 20k and 10nfs , than I do the alternative

    Thanks. So it may just give more control. Can’t hurt right?

    Just When I Thought it was Going to Be Easy

    I think your advice is sound. I left the board and this hobby a while back because I allowed myself to get frustrated with not having a formal electronics education and not understanding much of what I was doing. But I dialed that down and am trying to keep it a fun hobby.

    By the way VB, I did, at one point built a transistor based pedal which sounded fuzzy. The effect has its place, and it’s more a matter of personal preference. It may also be a requirement if one does LSD. Lol

    I was never a fan of fuzz even in my early years as a guitarist. I know guitarists like Hendrix made it cool, but it just isn’t for me. @AG. I take your point and thankfully the build enables me to curb the fuzz out or minimize it. on the topic of the 10k tone control, what would be the effect...

    Thanks Bertus. A possibility for sure.

    I am using a stainless steel enclosure for my overdrive pedal that I built. I am in the decorative stage. I am wondering what kind of patient would be best to use. I am thinking of designing a simple logo to put on the top of the box. Any ideas? thank you

    Thanks VB. Never been a fan of fuzz though

    Just When I Thought it was Going to Be Easy

    Ok. I will go with not buffering the second amp. I will first test to see if there is a second amp. I take your point about not being able to determine specs on kick offs. I once bought 2 op amps in a package from sayall for $11. Sure, they were from a storefront vendor but at the rate of...

    Question. As I can’t determine if this op amp is dual,or single, how important is it that the second op amp be buffered? And if it is important, I guess I can assume the pin mapping for a Tl082

    It’s a good thing the mystery was solved. Do you recall how many posts I made with peculiar pin readings? ( I can hear @AG saying I told you so). Lol the only positive outcome is now I have about 50 op amps that I can deploy in my experiments

    On the op amp, the following is written: 19ALE3M TL081CP There is also a pic that I posted on post 12 of this thread

    @AG. I think you’re right and I know you have warned me about this in the past. Back to the reason why I have used Amazon. $20 delivery fee from Digikeys.however, I have signed up with Nuetrix (sp?) and I will see what they are like in the future.

    Thanks guys. I know the data sheet could tell me. The issue is, why does it have the wrong labeling on it and, given that, how do I know for sure that it’s a dual. It says it’s a TL081 but it behaves like a TL082, but what if it is a different series altogether that is a single

    Just When I Thought it was Going to Be Easy

    Mystery solved. I breadboarded the single op amp I have. Turns out that the Pin mappings do not subscribe to the TL081 op amp. Rather, the main differences are in two pins: VCC is Pin 8. (not Pin 7) Out is Pin 1 (not Pin 6) I bought a million of these op amps on Amazon. I wondered why they...

    Just When I Thought it was Going to Be Easy

    Thanks for the suggestions VB! At last, it is done. See pic. Are those fancy and edgy black racing stripes on the side of the box? Or, is that black electrical tape, made to look like fancy and edgy black racing stripes to cover up where I drilled holes that did not end up working out? I'll...

    Just When I Thought it was Going to Be Easy

    Turns out that scotch tape did the trick. However; everything works now, until I close the box firmly shut. Something must be shorting because it stops working. It works even until the box is almost firmly shut, but when I tighten the screws to finish the job, it no longer works. I think it is...
