Best ABY around
Initially I started with a Morley ABY. Although it switches fine and silently, it doesn’t allow to break ground loops or include a switchable buffered interface like the Radial. I have two Radial ABY’s. One earlier generation without the LED’s, one later model with LED’s. Both are top notch. No tone loss (to the contrary), no noise, sturdy package. I love them!

Rugged and easy to use
Great A/B/Y box. Equipped with lift, isolation, and polarity switches to negate any types of feedback or interference from ground loops or other electrical issues. It is a passive device and so it has clunky switches and no LED, but those are not a big issue. LEDs would be helpful, especially when switching from both to just one amp, but that's why they have more expensive versions.

Yeah, I've relied on the active tonebone for years. Maybe over a decade.... not sure. Its pretty much as good as ABY gets and I've tried everything but the Lehle. I think the BigShot is the only passive box I would mess with.

Definitely worth the money, especially since one of the active ones would basically cost as much as a new amp.

I used both the Morley and the Radial side by side. The Morley is simpler, doesn’t allow to lift ground loops and no buffer either. Still a good product, but Radial is the better option.
