For a few years, I owned a Biyang Mad Driver, which is basically (or similar to...) this same TS, in the smaller MXR- size, Baby Boom series.I could not afford a "real" TS when I wanted one, but I was able to borrow one to reverse engineer. The circuit is incredibly simple. I built my own for about £12 (in 1981). Sounded identical.
About 2002 I bought one of these...

The Biyang Tonefancier x-Drive OD-8. I contains every version of the circuit created by the Ibanez and Axion pedals, and you can switch between them all. It even comes with all three integrated circuit op-amp chips which you can swap out as you wish.
Is it a great pedal? Sure, and it is cheap because they are really cheap to make.
Will it make you sound like SRV? No. SRV would have sounded like himself through a Katana.
Try a few pedals and buy the one you like, irrespective of brand or endorsers. What will inspire you to play is a sound you enjoy. NOT sounding like a player you enjoy.
I have liked all the Biyang pedals I have tried, but they are a bit, erm, shiny and bulky...For a few years, I owned a Biyang Mad Driver, which is basically (or similar to...) this same TS, in the smaller MXR- size, Baby Boom series.
It was a very good, cheap Tube Screamer ( but sold it as really prefer other OD's)
( starting with the GFS Brownie Classic years ago now, I've been a Biyang fan; own a few others)
I've been experimenting with pedals a lot the last couple months. It seems for me like once I find such-and-such pedal with the knobs so-and-so settings and it sounds good, the next time I'm playing something similar that's the sound I'm imagining. So why not go with whatever worked.I got 10 different OD/distortion/boost/crunch pedals. Sometimes I just reach for the closest one because it’s handy. And I can dial in similar sounds with different pedals.
I’m guessing a lot of the famous recordings are done in a similar way. The pedal was in the studio within arm’s reach at the time, or it was easier not to unplug a certain pedal and get another pedal and plug it in. Sometimes a player doesn’t want to interrupt the mood or mojo by plugging, unplugging and dialing in.
Famous recordings are already done. If you want to cover the song or create something similar, make it your own, put your own stamp on it.
I'd add that they also work well into lower priced low-wattage valve amps that are all headroom and no "grunt", though these are rare, and into class A amps like the Vox Ac 4, AC15 or AC30, but less well than a more "treble-booster" style pedal.They work well with high wattage Fender amps and provide the perfect volume and voicing boost for leads.
