YJM308: NEW Demonfx DOD250 MXR DISTORTION DOD 308 In one pedal two toggle

NOTE : About this switch(MR/250/308) is only a little different :

There are very few differences between the three originals pedals(mxr distorion+ dod250 and JYM308)

so only you can find a little difference with a high-powered speaker and adjust the knob In a particular position.

Or When playing a sweep meaning when playing multiple strings of different frequencies at the same time

you can see the difference between these three switch(MR/250/308)).
