One little niggle I've noticed about the Joyo is that you have to have it boosted from the clean signal to match intensity in the low end in a mix. On today's gig, it was sounding a little bit weak in the lows, and I turned it up a bit, and all of a sudden it wasn't weak anymore. I guess that's par for the course in a lot of OD pedals, though.
That's very common even in boutuiqe pedals costing $200 or more unless you have a clean blend
Usually have to play a give & take dance with the gain & volume knobs
