«  Handy »

I bought there many years. I use it as my alternative configurations (if I use my G-System to control the channels of my amp)

There is not much choice for this type of product, so it's great.

This is a great tool to control midi channel switching amps and also with the A / B box, direct the signal to another amplifier or other multi-effects.

Quality / price ratio: perfect

Over time, I think it is an effective, simple to use and allows you to use a variety of configurations.

One flaw, mine sometimes loses its programs if there is a "wild" power failure but it is so easy to program as it is not too inconvenient.
