Re: Fender Supersonic Buzz
I have the head version. There's a little 60 cycle hum when it's running. It doesn't seem to loud to me.
The tones are great. The Bassman tone is fat, smooth and warm. The Vibrolux tone sound thin at first, but if you're listening to it right after hearing the Bassman setting, and suddenly all that low mid drops out and all this high end comes in, it'll give that impression. Play with it a little while, and you find out it's a clean, detailed tone, but still warm. Vintage bridge humbuckers still sound sweet and warm through it, even with all that high end. A guitar with a JB will sound a bit ice-pick shrill.
The burn channel is wonderful. Each of the two gain controls add a different flavor of gain. One adds a warm, smooth classic crunch and drive, while the other adds a more aggresive, metally distortion with plenty of fur. They can be blended to taste. You can get anything from a smooth vintage crunch to a scooped metal tone, and blend the two to get the right balance of Marshally crunch and modern distortion. And either way, you never get harsh, icepick distortion. It always sounds smooth and pleasing, even with a scooped sound with the treble control maxed.
I agree that it sounds great with the gain cranked. Even with the gain maxed, it still sounds tight and defined. But I love the medium gain tones the amp produces too. For the money, the amp does a great job of letting you set it so you get some crunch when you play hard or have your guitar volume up all the way, and cleaning up when you play softer or roll back the volume. That's something that's important to me because a lot of the tunes I've written have rhythm guitar parts that have dynamics created by playing softer or harder. The Super Sonic does a fine job in that dept.
The tone controls are a masterpiece. There is not a bad tone to be had. Turning the treble all the way up does not add harsh, earpiercing shrillness, with the possible exception of the Vibrolux channel if you play a guitar with a very edgy bridge pickup through it. The bass/mid/treble controls on the burn channel produce really nice tones no matter where they're set.
The two voicings on the clean channel contrast each other nicely and together offer all the variety of cleans you could want, and the two gain knobs on the burn channel, each of which sound different, offer the means to get a great variety of overdrive/distorted tones, all of which sound good!
I'd really be interested in how the SuperSonic head measures up against the 5150 III!!
