I'd purchased a Joyo Ultimate Overdrive for $35 new after hearing a couple of really good demos.
It's an interesting pedal. Sound-wise it doesn't shape my tone like my TS9 does, nor is it as sharp sounding as a Boss SD-1. It's definitely on the warmer sounding side, imo. One thing I did notice is that it has a lot of low end to it. Making it a good pedal to fatten up an otherwise thin sounding tone.
Value-wise it's pretty hard to beat.
