Review: Yah is good. - Decent di box, not the smallest or lightest but it's good quality, well made and does its job, I went to a venue or two that didn't have one so I made a habit of bringing one in my bag to every gig just incase. This didn't make it though and I wen for the smaller lighter and cheaper behringer which worked just as well. Reduces noise as it should giving good sound quality, easy to use too. Listen to the video clip tell me it's noisy? Lol...
Review: Perfect before an audio interface that had too hot an input for DI guitars - I have the first gen Scarlet 2i2 which was notorious for having hardly any headroom on the HI-z input when recording guitars , essentially forcing you to use a DI box to get more control. Enter this device. For the price, this DI box does exactly the trick, it gives you a balanced signal into a DAW which is perfect for recording DI guitars to use with amp sims. Obviously, it won't sound as a good as a Radial JDI but for a fraction of the price this gives you a very clean signal with excellent noise rejection. To me it sounds better than the HI-z did. Bare in mind it is passive and using it with passive pickups like I am means that there is a slight roll off in the highs, but to be honest it's only very slight and actually really helps with my Telecaster that has an extremely bright bridge pickup, just takes a hair off the icepick highs. It imparts a warmer tone than the HI-z does but with plenty of clarity still. An active DI is the preferred way usually with passive pickups, but they are considerably noisier for the use of what I do. Overall very recommended and the box is a nice size. I could care less about the design on it, but does have its charm.
