UA is a company that charges a premium, yes. But I feel I’ve gotten excellent value unavailable anywhere with every purchase including The OX. This attenuator has worked great, I haven’t experienced the microphone distortion. I’m running modern guitars through modern amps with fresh tubes. With included presets sound comes out of the optical and into my x8p as a beautiful soundscape. If you understand a little more and go beyond presets, there is quite a bit to adjust to your liking. I’ve laid down quite a few tracks that got a tone and effect with a desired separation at a minimum of effort. If you use the cone cry feature with some understanding as well. You can replicate and amp that barks and squeals, as intended. Not microphonic. Now I’ll add that I run a clean amp platform and pedals for beyond that. I reuse power section. El34, EL84, 6L6 AND then switch out the pre’s. The victory v4 series all four (kraken, sheriff, countess, copper) so 5150, modern Marshall, plexi, and ac30 essentially. Again great results on all of it. Ran for several years now. Very satisfied with the product. As with everything, there can be an amount of user error. I haven’t met anyone with a bad ox experience. Different gear has different quarks. Learn your gear, and you can love it for what it is then.
