Does exactly what it advertises
My studio purchased the Radial SGI for recording guitars in the control room with combo amps in the live room. I tested against a 15ft cable with pedalboard and amp both in the live room. I thought this would be a worst case scenario given passive pickups of a strat and Les Paul (covering single coil test and humbucker test) would be much more particular about load impedance than a buffered pedal board. The SGI was actually a bit quieter in terms of hum and line noise than the cable with the ground lift which surprised me. There was little discernible difference in signal level hitting the amp when directly plugged in or to the pedal board when it was connected. The drag control on the SGI was a very nice feature. Somewhere just above 50% seemed to be comparable to the direct cable for both guitars in terms of high end rolloff. When drag was set to max, the SGI was noticeably brighter. This is a great option for impedance matching to get the fine details that I was most afraid of losing. The range of the drag control seems like it would cover most guitar and amplifier combinations. Typically Iíll keep a pedal board in the control room for adjustments on the fly, and with any buffered pedals I would imagine the drag control will have little to no impact. Still it is good to know that even in the most demanding situations, I have a rock solid tool.
I did notice that the SGI is sensitive to XLR adapters. I first attempted to wire through the XLR wall panel in my rooms and noticed the XLRM and XLRF ends were wired backward from the SGI, so I used an XLRM-XLRM and XLRF-XLRF adapter on each to make the connection. I get no signal flow when wired this way. I assume the phase is inverted between the cable and adapter and that is causing cancellation. Instead I used an XLR-TRS connection on my wall plate with corresponding cables. This works fine. Itís just something to note in case other customers experience this.
I am extremely happy with this engineered and packaged solution vs. the direct box / reamp DI combo that it is replacing. Per usual, Sweetwater support was excellent in guiding to the best product based on needs and shipping time is always lightning fast.
