Yes that's what I did today, and I'll be honest I just understood what you said. Even though I didn' have an op amp then.
I thought Banzai was a good vendor but I was mistaken.
1. They deleted my reviews on several products because they were negative.
2. They didn't respond to my emails related to LM308 being damaged.
No, but they were really cheap.
That really makes me mad too. Damn that was the most non-expecting scum.
Overall, that pedal build made me study more about electronics and understand whats going on. I can say that when I see an overdrive/distortion schematic I can recognize the function of the components.
So, the results are not bad at all.
Thanks everybody!
Agree. I find I always learn the most from my failures, too.
Congratulations on sticking with it till you found and fixed the problem! 🙂

I have to acknowledge that banzai returned my money for LM308 with a coupon of equal value after I posted here.
It is quite possible (and quite likely) that Banzai had no idea they were selling junk. I doubt they test parts they buy from their suppliers before selling them on to their own customers.

They'd be seconds, being resold as the real thing.
To be clearer: normal manufacturing process has at least one quality inspection stage, at which anything scratched, dinged or otherwise screwed up gets removed from the official supply chain.
The scrap then gets disposed off. Anything unsold at the end of the product life gets scapped. Same when the shelf is needed for something else. Or when the shop/warehouse closes down. Or if the packaging gets damaged.
And so there's an entire second industry dealing with all this scrap. Some of it's perfectly good stuff and gets flogged off to thrift stores, old fashioned hoarders and ebay dealers (and one of my wine suppliers). Some was rejected for good reason (like the brake light I installed in one of the family cars recently which has dodgy solder resist - but still works)
Some dealers take the time to check what they've bought and confirm it's genuine and charge accordingly (e.g. those in NOS military electronics business selling to defence forces still using and maintaining stuff designed late last century) .
But most people trust what is written on the outside of the box and don't waste time (or money) checking any further. After all, it's all surplus or seconds. Likewise, when an order arrives, they'll fill it from any supplier they can find. If there's a problem, we'll deal with it later.
And that's how leadless pencils end up at the two dollar store.
