Nice ABY

Seungku 16.04.2018

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.

Great piece of gear!!

Used to have problems with ground loops while playing in stereo, the noise was just unbearable. Since I purchased this well constructed metal chassis pedal everything works as it should, not to mention that both amps work in fase now. It's smaller than it seemed in the photos which is nice to save space in the pedal board. No power needed unless you want to know where you're at, and in that case the LEDs let you know if you're playing A, B or both amps. Probably the most robust pedal I have, I'm very happy with it! Highly recommended if you play in stereo!

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.

Solid and works!

Frednugent 29.05.2019

I love Raidial gear. Just found out about them and this is my 2nd piece in the last few months. Like the JDI this piece just does what it should in a really solid and clear way. Split your signal to A or B or have both playing. I just tried with vocals through 2 little amps for a live show and it worked perfectly. Its passive so you dont need power (unless you want the LED). It's a bit on the heavy side but still small. I can tell it's going to last for years. Solid, easy, small = Great.
