Welcome to the forum! :wave:
There are a few things I've noticed about tube amps, coming from many years of solid state.
First, they are build to be played loud! They sound very good at low levels, but if you're looking for breakup you wont find the sweet spot until the volume is half or more.
Second, they need time to warm up. I've noticed with my little Champion 600 and my Classic 30 they sound fine when I turn them on, but a half hour later they sound great.
Third, there are two "tube sounds" that people search for. A tight, modern, heavy metal distortion is achieved by saturating the preamp tubes. That's what the Gain is for. A big, warm, blues/classic rock overdrive is achieved by saturating the power tubes. That can only be done by cranking the volume. If you have a Master Volume or an attenuator you can get that sound at lower volumes, but the principle is the same.
The SCXD is a genuine tube amp. The signal goes through a tube preamp (12AX7) and a tube power section (6V6). It also has an effects unit in it (DSP), but if you use channel 1 it's a straight forward Class A sound.

No kidding! I stand corrected, thanks
The SCXD is not a pure tube amp. The OP correctly classified the SCXD as a hybrid. It has a solid state preamp, even on channel 1. The 12AX7 is a phase inverter / gain stage to the power section. That said and as a happy SCXD owner it has a great tube tone on channel 1 and produces excellent tone at lower and higher volumes

Thanks for the great replies, everybody. Lots of cool, knowledgeable people on this forum. I appreciate it. All good advice and stuff I'll take into consideration.
General questions: How can you know for sure when tubes need to be replaced? Does it just kind of die out on you? Also, what is "biasing" and how does it work? I don't plan on doing any mods or anything that only a tech should perform but I'd like to know just for the sake of intellectual curiosity. (Sorry for potentially dumb and/or obvious questions).
EDIT: Also, about hybrid amps... does the solid state preamp really affect your tone? I know Meowy said that the SCXD is more than capable of getting quality tube sounds but I'm wondering what the practical differences are, in terms of sound, between all tube versus hybrids. The SCXD sounds quite excellent to my ears but I haven't spent enough time experimenting with it to say that it's ideal.

Something old and bluesy, with maybe with some classic rock crunch on tap at the most? Or something tighter and a little more "rawk!" It makes a difference, you can get either, but really get both convincingly. If you want to experience a tube amp, then why not get a tube amp. A simple design with a few bells and whistles and as basic a circuit as possible, the less there is in the chassis, the more each component, including tubes, really gets to shine. I won't steer you away from the SCXD, it's a nice sounding amp, with swiss-army knife capability, but there is something nice about a simple tube circuit with the volume turned up to the saturation point and the guitar turned down a little to compensate. Give us a top end number on price, a few examples of the tone you want, and an idea of the playing setup, and we can steer you right. I try an afford endorsing amps that are more than 20 years old because you never know what TLC they may need to be reliable, I love vitnage amps, have plenty, but I do my own amp work, but I don't want to saddle someone with an issue that will require bench fees right out of the gate.
I have been away from guitar playing for years now and I'm just now getting back to it. I love Tele's and I'm now a proud owner of a brand new Classic Vibe 50's Tele. I also need a new amp and I definitely want something powered by tubes. In the past, I've had solid state amps for the usual reasons: cheaper, easier to take care of, smaller and lighter but the tone was lacking and I'm not going through the disappointment of constricted, nasal, fizzy tone. I want something warm, organic, loud and rich... I want a tube amp! It doesn't have to be very powerful and it doesn't have to be expensive, so I am leaning toward the 15 watt Fender Super Champ XD hybrid amp. Do you think this is a good choice? What is the practical and tonal differences between all-tube and hybrid amps? More importantly, what do I need to know as a tube newbie? I have no knowledge of care and upkeep, except that I am aware that tubes do need replaced from time to time, correct? How often? Is overheating a serious problem? Are there things I need to know for transportation or regular maintenance? Maybe I'm just overthinking? :rolleyes: Thanks for any and all words of encouragement and information. Also, I'm new here so Hello. :wave: Is this the part where I ask "wat is teh best guitar 4 M3+AL??!?!"
