With all the talk of the BluGuitar & Helix Stomp & whatnot, I thought I'd just chime in to say that after a week it's a pretty impressive unit for the price. For me, the VHT Pitbull and Randall Satan are two of the standouts so far. I haven't run it into an amp/poweramp but going direct into my audio interface, it was exactly what I was looking for. I would have really liked to pick up a Helix Stomp but it's 1) just too expensive for my budget and 2) I was only really looking for amp sims & didn't want/need all of the effects. I also looked at the GE-200 and Hotone Ampero but after a bit more research, I remembered the Preamp Live and apparently, they doubled the list of available amps since it first came out. I found one for a decent price and was not disappointed. For metal tones, there are literally more amps to choose from than there are available patches. Some of the good points are: -13 available boost/dist pedals (pre-gain) and 2 post for volume boost -10-12 available slots for loading irs without having to overwrite the stock ones. -Pre AND post noise gates (which work really well) -10 power amp sims vs the 4 that are available in the Radar. -There's 104 different amps (clean to high gain) to pick from (which is even more than the Pod X3) -The fx loop can be set to either serial or parallel. -It has 2 switches so you can turn the cab sim on/off for both the 1/4" and XLR outs. Some of the 'not-so' impressive things would be: -It really could stand to use more than 12 memory banks given how many amps there are. -Seeing how Mooer makes the Radar, they should have included the eq section to help 'fine tune' the ir loading. -There's no way to change the amps without either connecting it to a pc or using the app. Overall though, for the price of 3 or 4 of the mini pedals, you absolutely get your money's worth.
