Sounds great with the high speed amp chip installed.
Nice sounding amplifier, used it in an acoustic guitar with a piezo sensor. Easy to change the gain by changing r5 for one channel, and r7 for the other.... gain is r5/r6, and r7/r8. Installed is 100k and 2.2k. Maintain the 2.2k and change the 100k. Has a voltage gain of 45, and a db gain of 33...

Not bad fot what you pay for them.
I was not expecting much out of these. But they actually work pretty good and have good sound quality! No instructions so you will need to understand electronics to be able to use them. But overall, good for what you pay.

Caution
Why did you pick this product vs others?:Bought these thinking that I might need a preamp for my new dynamic microphone. But there is a problem. This product comes with no documentation. That means you are taking a big risk to use it without spending a lot of time reverse engineering it to make sure it won't destroy your equipment. And that takes knowledge and lab equipment. This is a common problem for such cheap Chinese products, but I could find nothing anywhere on the net to provide any information on the circuit. So, for me, I'll just throw these in the junk box and look for a better (safer) solution.

They don’t work.
I ordered a tree peace set got one item twice. Seller gave me a refund. But the one peace I have doesn’t work. Yes put together correctly. I know electronics. So no money lost thanks to refund from seller. Thank you.

tiny connectors but works great
I used it to amplify the piezo in my acoustic-electric guitar after the original electronics fell apart. Sounds good but I wish it had larger lugs to solder on. Be careful no components on the board come in contact with stray wires or your shielding.

No Instructions/schematic
It is probably a good product, but it is useless to me because there were no instructions or schematic with the product. A link to a schematic would be enough, but there is not even that. What am I supposed to do with this?

Buy extras because a lot are no good.
Great sound when they work. Out of 9 purchased, several where noisy and 2 were dead.
