PDAL simple to use and reliable.
No light, no pots, but instead trs little greedy in stack.

UTILIZATION

No problem, no need for instructions, after the 9 V battery inserted, the branch and it works.
The pedals set off by pressing the bottom, no particular problem.

SOUND QUALITY

The effects require a little practice, beginners at one is a little lost finding the right balance and sound effects but that hope comes quickly.
I use it with a Stratocaster and a Marshall amp, allows very awesome sound.

OVERALL OPINION

This is not the super pedals, but the ratio quality price is unbeatable and will make many services for its simplicity and reliability.
