HD500 itself has no hierarchy, but this HD series has hierarchies, and the latest model is HD500X.

The differences between HD300 and HD400, HD500 and HD500X are as follows:

The difference in appearance is obvious.

When HD300 switches the timbre of the troupe, it is necessary to step on two nails at the same time, which is a bit cumbersome to operate.

The difference between interfaces, the higher the model, the richer the interface. ? (HD500 and HD500X have not changed much. The pins have been changed and the processor has been upgraded. There are no special changes in the rest. )

There is no difference in timbre.

The higher the model, the more types of simulation.

The effect chain position of HD300 400 is fixed, and the specific position of the effect on the effect chain cannot be changed.

A suggestion: If the subject wants to start with the effect of HD series, it is suggested to choose HD500X, because HD300 400 500 has been discontinued. Of course, the newer the technology, the better the timbre function.
