Idk if it’s just me the presets that’s are labeled have metal An use the super chunk disortrion tones, it sounds almost to perfect, you guys think the lack of natural distortion or that different air the tubes amp breathe so to speake makes other think some thing isn’t a solid good in terms of sound? Just a random thought was messing around with the GT an my orange crush 35rt and really trying to get the GT to sound just like it so show a buddy how badass these things were. While yes we both being musicians knew we liked the tubed amps still overall, but I noticed today for me anyway the way I dial my settings I don’t get much feedback? You guys? Palm muting on the metal preset is fun although I play jam/blues/funk/rock music Its still pretty digital sounding but not in a bad way no feedback or hiss with that much doistortion on any amp is near impossible I’ll never gig with a high gain tube amp even 40 watts without somethitn to bypass it when I need I always make sure my presets don’t allow for mch feedback burn the main point of this post is ive seen others say it so ours ears changing to a new more room filling clear on all Angles Sound it’s a thicker, more bassy then a lot off guitar amps I fee like. But it’s not a bad thing.. fenders right there will this, I don think I can trust it cause of functionality more than tone for live but I’m tryin my best to keep it as a rehershal and backup amp. Idk though I’m waiting on the floor mode lol ;) the money for This could help with that I’m over wiring pedals together An board An other factors possibly hurting my tone on board ljek the GT or floor models are legit I wouldn’t
Even really Care for the cabs an heads just the fx haha

This would be a lot more "readable" if you put periods between the sentences.

The digital amps don't feedback much because there is a relatively large delay between the signal going into the amp and it finally coming out to the speaker.
An analog amp has a short propagation time. It is usually measured in degrees of phase shift.
360 degrees of phase shift causes positive feedback, so analog amps must remain under that. But as frequency goes up, propagation time remains the same and hi frequencies get shifted more. When they start reinforcing each other, it feeds back.
Digital amps that I have measured have about a 1.5 millisecond processing delay, or latency, before the signal comes out. This delay prevents the signal from reinforcing itself as the string is somewhere else entirely by then.
Its about as long as the wavelength of a middle A note.

Hmmmm....then mine must be a magical one because i can get feedback pretty easily, even at very low volume with enough gain. I don't see how that latency would matter because feedback is the process of the speaker exciting the strings and causing them to vibrate resulting in a feedback loop. It shouldn't matter if there is latency because the strings will become excited by sound waves regardless of when they hit the strings. Mine appears to prove that since i get feedback as good as most tube amps Ive owned. Some were better, yes. But mainly due to the mid content. Certain mid frequencies will cause a rig to feed back much easier which is why marshalls tend to feedback at the drop of a hat. The louder the more easily, tho i find my GT feedsback at very reasonable levels. Even more so if i use a middy patch.

[quoteThis would be a lot more "readable" if you put periods between the sentences.]This would be a lot more "readable" if you put periods between the sentences.[/quote].......................not. help.ful........... I am on a iphone I don't care about periods and such my gear head ADD brain just starts rambling, don't be that guy. lol jk man.

I don't mean no feedback at all of course I have just noticed in certain presets, idk if its just a mixture of a bunch of things but the feedback is not as loud or piercing. I do know solid state generally don't feed back as much but I hear it less in these amps maybe its just me. Like it was mentioned you can still get plenty of feedback if you try hard enough just something I thought one night playing at low volume which it always sounds better with the GT but my though was maybe people just aren't use to a such a clear signal. theres so many factors eliminated with onboard fx less cables, power supply what not. Don't get me wrong I think there are presets that just sound plain digitial. But the cleans have always impressed me a lot and even my buddy who had the kemper thought the GT did fender cleans "especially after eqs" better then kemper. I do like the ts9 and modulation effects, anything heavier it sounds thin, muddy, and just idk not as full an warm but I use the GT live like a floor board with a speaker by ABY pedal to an another amp. I run both amps for cleans the GT is the fx while the other amp is dry it actually helps a lot!!!! I think I want to try the Bugera V22 for the price point and the cleans of 22 tubed watts is a hard pass up. I think the Bugeras are gaining some trust again. Its not anything special drive wise its okay, but the cleans and speaker sound fantastic swap the tubes out could be a cheap rig with a good sound. I don't want to part with my GT though I love the versatility, and FX and I love FENDER!! I woulda got the blues jr nos 15 watt I just don't think enough headroom will be there. The GT in a few years will be top contender it already is better then a lot of amps that get high marks that maybe shouldn't.

And I am answering you back on an iPhone. Notice there is no issue with punctuation. After each complete thought, press space after the last word until a period is automatically added. Not any slower than your way. :wink:
