Quality:
Seems well built

Value:
There are a few other switches that are a little cheaper.

Sound:
This switch gets the job done if you need to use two amps but there is an annoying electrical hum as well as some tone degradation. The package of this unit recommended the Ebtech Hum Eliminator to help with the hum, but I don't really want to shell out $60 to find out if it works.

Ease of Use:
It's pretty straight forward, and the led's help you see what you're doing

Overall:
I've had it about a year and haven't used it in probably 7-8 months. I got it for a sketchy rig I was using at the time. I would like a way to switch between the Marshall and Fender amps I'm using now, but I can't live with a loud hum coming from over $3000 of amp.

Feature:
It has all of the features necessary including led indicators so you can see how it is set.

Quality:
It's solid and well made, except that I don't like having to unscrew 4 screws to change the battery. Considering that the power is only needed to run the led indicators, it should have a wall-wart plug on it too.

Value:
It's hard to rate it on this factor, because I'm not happy with the performance.

Desirability:
It;s a rectangular metal box with 2 switches, 2 leds, and 3 plugs. Couldn't get much sexier than that!!!

Sound:
It adds a fair bit of hum, even with the hum eliminator I bought. There is also an unacceptable amount of crosstalk between A and B. The undesired output does not mute completely, so, without a volume pedal as well, you can't turn off either amp. This problem has increased with time (about 3 years).

Ease of Use:
It's about as straight-forward as it could get.

Support:
no

Overall:
I wish I knew about the cross-talk. It was bearable at first, because it wasn't very loud. Now, I feel it's time to find a better one.
