I've not tried the Sweet Baby but my oldest got a Joyo Vintage Overdrive for Christmas last year. It's a TS808 clone and I have to say, it's pretty spot on. I compared it against a real vintage 808 from 1981 and I could not really tell the difference. The Joyo is maybe a touch brighter but you really gotta listen for it. An incredible value for under $40.
I tried the Joyo Vintage OD and found the noise floor too high, which could very well be a unit-by-unit QC issue. I also tried Caline's Sweet Honey clone the Queen Bee but thought it was too thick in the lower mids.
I have a Joyo Sweet Baby arriving tomorrow, so hoping it is as good as it is billed to be
I've not had a noise floor issue with it. No more noisier than my TS-9.
