I've got from Joyo: Vintage Overdrive: Great OD sound and nice transparency, didn't colour the sound. I lent it to a friend and after i got it back, it's just been sounding off... like a little distant or muffled. Good chance i'll buy another one to replace it. Ultimate Drive: Another great OD. In my opinion it gets a bit crunchier than the Vintage Overdrive, so it's a bit better suited towards rock. Beautiful sound and so far bullet proof performance. British Sound: Don't use this much. When i turn the Voice and the Gain up high enough to get the crunch i want, the pedals gets annoyingly noisy. I'll most likely get rid of it. Analog Delay: If i use a battery, it's dead within 5 minutes, absolutely needs to have a wall adapter in order to work properly. The first one i got actually arrived unusable, creating some pretty crazy noise, or none at all. But they replaced it for free. But overall all it's a pretty decent analog sounding delay. Think i'll stick with my MXR Carbon Copy though. Joyo Clone of the Korg Pitchblack tuner: solid and heavy and built like a tank. It does it's job fine, but i find the response is a bit slow or delayed. I often have to mute the guitar, wait for the display on the pedal to go neutral, and then tune the string. Not a big issue for just tuning up and playing at home, but a big annoyance for live playing. Even though there are some less-than-positive overtones in what i have written, i've overall been very satisfied with Joyo and recommend them to all my friends, and i wouldn't hesitate to buy more from them in the future as long as the prices stayed low. i got all mine from wtfaccessories and never paid more than $35 (including shipping) for any of them. Their listed prices are higher than that now, but they list coupon codes on their site that brings them back down into the $35-ish region (excluding the newest models).
