However, hard to find any difference between sound from the iRig HD2 interface I replaced this with. I’ll add some thoughts about additional functionality with Bias FX. It retains whichever model you select before power off. Not a huge game changer except if you wanted to record direct / clean tones. Three tones provide a bit of Color to the input signal.The clip indicator would have been sufficient, though I rely on the input VU to monitor the signal for that. The three indicator lights show clip (always on), direct signal (only on when direct blend is >0), tone (only on when tone model is set).It does however flex a bit and I wonder if it’s easy to damage if I wanted to keep it on the floor when on stage. Big knob is nice and is of the digital encoder type with a push button to switch functionality.Not sure if it’s meant to be removed but mine looks it’s a well worn device after a week of use Front panel also has an extremely soft plastic cover which will scratch at the lightest rub.There are VU meters for input and output which are also extremely useful. I found the quick access to input and output especially useful. Pushing the knob toggles between Input Gain, Direct monitoring blend, Tone type (preamp model) and Output gain. Front panel is nice with a big lcd single Color display.The odd symmetry works when placed horizontally on the desk as the display is angled towards you, but all the read outs are for vertical orientation. I could see it being used on the floor, but that knob would probably break if bumped. Feels nice and solid and suited for desktop usage.
