I ordered a HeadRush FRFR and it was delivered earlier in the week. Finally got around to opening the HeadRush FRFR. Put it outside on my deck, along with my strat and my Zoom Lynch Pedal. Took longer to find a extra decent surge protector in my house than it did to unbox and plug everything in. I started with a clean patch, just to see how the minimal settings were. I was happy to see that you can get some no-ear-splitting room level settings between 0 and 1 rather easily. Now it came time to push it a little. First up to 2, which is a nice decent level for screwing around on the deck. But, why stop there. I tried 3, then 4. Level 4 was loud enough that the garbage men, who were on the next street noticed me immediately. It also gave an excellent amount of feedback on the guitar, without needing to put the guitar right next to it. Granted, I was only about 4 feet away, but it was loud enough for the neighbors to hear it at least 6 houses down. At that point, I had to bail. It's expected to be around 100 degrees today, and it felt every bit of it around 11:30. I'll push it some more another time. Definitely going to crank it on July 4th for the Star Spangled Banner. One thing really made me laugh. I didn't notice it before, but the levels go to 11. It's one more better than 10 So far, I'm really liking it. I'll be doing many more tests, and then do a comparison between my studio monitors and the HeadRush mic'd into my DAW to see if there are any tonal differences. Eventually, I'll do a full review. Right now, it's just too new, and any (honest) reviews would be skewed.
