I've heard they're all affordable little clones of the real popular pedals ie tube screamer, dynacomp, big muff etc. and pretty sure they're all true bypass aswell.

How close to the real tone are they?

Apart from joyo, guitar tech and mooer, do you know any other manufacturers that are doing the same thing?

Have you tried using the search bar?
Joyo, mooer, biyang, behringer, danelectro, are probs the most popular current production ones.

A lot of the manufactures sell pedals under different names too, for instance joyo and harley benton are the same. As are GFS and biyang.

IRL almost all mass produced cheap pedals are clones of popular pedals. Just some of them are better than others.

Anyway, search bar - this kind of thread has been done multiple times in the past.
