Nice ABY
I needed to run two amps at the same time, while I was recording. So, I was in hunt of nice ABY switch and this came up.
Pro: It has every features proper ABY switch should have. Built like tank, has enough LEDs so you know where your signal goes. On output [B], ground lift and isolation transformer to eliminate ground hums and buzz, can reverse polarity to prevent phase problem between two amps. Very effective and thoughtful.
Con: There's noticeable tone shifting when you engage 'Isolation transformer' on. So you had to tweak amp's knobs on output B again to get the sound you like.
If you are looking for proper ABY switch, look no further. Get this. I am giving just 4 stars because after recording, I hardly use it in actual gig or practice situations.

So far this meets my expectations well. Have used it to send one signal to an amp with solid state preamp/ tube power amp, and the other signal going to DAW via a USBinterface. Very quiet. Also worth mentioning I used an isolated power supply. When tried with 2 Amps, the previously mentioned one and a Blackstar id core 40 v2, ground lift helped to remove some noise. However there was some higher pitched noise from the Blackstar. I suspect it is something to do with the digital amp circuitry. I am yet to try the device with two completely non digital amps. With both setup scenarios I did not notice any tone loss.
