    I bought a Super Sonic from Musicians Friend,
    Plugged in my ASAT Special, sounded wonderful, just as I expected.

    I noticed a huge hiss starting to form, I put a JJ in V5 and that quieted it.
    But then, it started spurting and popping but only when I played a G tone
    any G except the highest at string 1/15.

    So I go to a local store and luckily they have one on the floor with the
    blond/oxblood grill, so I bought it, now I own two. Anyway, about a half
    hour into playing it happens to the new one, however it crap out on the
    F# tone this time.

    What in the world could cause such a weird crapout?????

    I love the tone of this amp, always have, but come on.

    Thank people

    Have you tried substituting another 12AX7 into the other preamp slots? If not, start there. Bad tubes can do NASTY things. Get a new known good 12AX7 and start subbing it in each slot - starting with V1. Do this one by one until the problem goes away. More than likely - you're a victim of noisy preamp tubes.

    If that does not solve the problem - then try the power tubes. They rarely go microphonic but, can do funky things from time to time. If that doesn't solve it - I'd take the amp to a tech. The Supersonic is a good amp. I doubt you have a dud. Start with V1 and go from there! I hope that helps a bit!

    You didn't say whether it was a head or a combo. If they are heads, I'd take a look at the cab. Usually cabinet rattles show up between F and G.

    I would also check all the cables involved. and try a different guitar if possible.

    If the tubes are good, that's usually a sign of a bad connection/solder, sounds like they need to be returned for warranty work

    This is most definately an electrical problem

    Right now it's 4:00am but I will try the one good tube in all spots thing and hopefully that will be it.

    As far as the problem being my guitar, I got the amp to compliment my ASAT Special. Besides the problem occured with another guitar. Not as much but it did happen.

    Thanks all,

    If that's the problem what's the chance of that happening with two amps from different sellers. But yes returning of the amp would be appropriate if tubes aren't the prob.

    They could have been from the same production run, and/or the bad connection/solder are in different areas of the amps.

    I know techs that have had to reflow solders in tons or newer Fender amps to eliminate the"snap, crackle, pops. I think that Bill Webb reflows all of the ground solder joints when a Fender RI comes in for service down at Austin Vintage Guitars.

    You might contact your local amp tech and see what experiences he's had with newer Fender amps... might turn out to be cheaper than the shipping cost to just take care of it out of your own pocket if a local tech knows his stuff.

    Also, the tube you put in V5 might not have been a temp fix... the problem could have gone away when the amp cooled a little then returned when it heated back up.

    Did you try a different instrument cable when you tried the different guitar?

    This isn't an instrument cable, I wish it was that easy. :)

    Update.

    From what I can tell. IT WAS MY INSTRUMENT CABLE. I feel like an idiot.
    Even Monster cable goes bad.

    I didn't think it could be the guitar cable but it seems like it was and it only screwed up when playing a G tone. the correct pitch to cause the cable to vibrate and expose a short.

    SatelliteAmps thanks for the suggestion, you were right. :)

    YEA!

    Watch out, though. Because there are KNOWN issues with those amps. My local store had one in the store for two years, had it fixed twice, the second time, they actually fixed the design flaw that was killing the amp. Now it's unbelievable.

    So if the problem comes back, get it serviced.

    It is a super-sweet amp, though, isn't it. I predict they will be treasured by a lot of us for a long time.

    What do you understand as these issues? Like what was the flaw they fixed?
    This is the stuff I want to address.
    I'm already thinking of retubing it with TAD12AX7 or Tung-Sol and Some better Power amp tubes. :)

    As it is it's pretty super sweet, the Vibrolux is a joke with my ASAT Special, so a good tube for v2 may make it more useable.
    The Vibrolux sounded great with my sons Fender Jaguar. But that guitar doesn't deliver the goods when it come to the Burn channel
    that is where the ASAT shines big time. Same with the Bassman.

    Heheheheh, I had a bad speaker cable once that had me chasing my tail.
    It only opened when the amp was in the cab up on the speaker stack.
    The proximity to the wall made the speaker cable bend where it connected to the jack.
    When I had the chassis out, it wouldn't have any problem.
    Man, I thought I was going to have to tear the whole amp down to fix it.
    Then I got a wild idea and tested the speaker cable.
    Yep...

    I don't know what they fixed, but it wasn't just a tube change, but a flaw inside. Again, no idea, I just know mine is fixed.

    Funny, mine sounded just great with stock tubes. The burn channel with a boost is a little noisy, but not really much more than any other gain channel.

    It's awesome.

    It sounds so good I'm willing to get the fix.

    I checked out the Lonestar Classic and the ElectroDyne
    Both talk about tweed but they never get the Fender thing.
    The Super Sonic does it in buckets.

    For Example, I have the Zendrive 2 and have figured out my favorite setting for my Blues Deluxe. I can go BD and then Zen, big difference.
    With the SS you dial in a good Texas tone that kills, and when you hit the Zen there is no great difference, maybe more like a boost. I mean you hear the cascade but the amp is already there. Pretty much. I'll know more after tonight since I'm playing out for the first time with the amp. (I've only had it a few days)
