Hi Rachel, ya just gotta know Iād reply to this oneā¦ 
I got two valve amps. I play both a hollow body Casino and a solid body (reverend double agent w) thru them.
I like them both.
The valve amps I got are a Supro Blues King 12 (15w)(about $800 new, got mine for $400 used) and a '65 Fender Princton Reverb (12w) reissue (about $1500 new, got mine new for about 1100 w/a discount cupon from my local music store, 20% off 1399).
What I donāt like first.
The supro. Well, the handle broke while carrying it. Supro replaced at no charge. I had to put it on. The on/off switches seem kinda cheap. Iām not big into top controls which the supro has. plus, the knobs are small and the line on the knob is near invisible so very hard to āseeā where the control is set at. Granted, I guess yer supposed to use your ears for that. Lastly, the control words are upside down when viewed from the front. Only thing good about that is there aināt so many controls that ya can memorize where and what ea. control is. This amp has a boost and gain switch to add more of either. Neither are controllable other than on or off (with foot sw. if ya want). But they both add vol. when switched on. The gain more so. Like quite a bit of vol increase over where ya got the vol at before switching it on. The boost, less so, but still a slight increase in vol. which may not be what I want. I mostly donāt use the gain. Itās really high gain. About the only songs I play w/ that on is Revolution and god save the queen. Both high gain songs. The boost I use maybe a third of the time. It gets to EOB a shade sooner with the boost on.
Lastly, the supro has no tremolo. I like tremolo. And itās too loud if ya turn it up.
The prri, about the only thing I donāt like about it is no master volume. I love the tones at 6, but itās just to darn loud to play at home on 6. I usually play at about 4-4.5 which is just about where the tubes start to overdrive. Still, pretty loud at 4.5 too. The vol increase between 4 and 5 is very notable. 4 is to loud to play with my wife home. 3 I can get away with if I aināt strumming hard. I can do 4 if I use the vol. control on the guitar to tame the volume.
What I do like.
The supro. I love the cleans. Very chimey. Bell like. The reverb works well and I set it at about 1/3 on. Pretty much leave it there. It has a master vol. which is most usable. I play a lot w/o any boost or gain on. I use the pre vol. to add any dirt that I want. Adds pre amp distortion. Or I also go the other way to. pre vol. low, master vol. up. This adds amp distortion. Different kinds of gain, amp vs pre amp gain. This is useful.
The supro is also pretty portable. I like to play on my back stoop. If I want to do elec. on the back stoop, the supro is the go to as the cab is small and weight is 28lbs. Easy to tote around. Fwiw, donāt let the small cab spook you. It sounds like a much bigger amp than it is. Ya can even get to much bass out of it if ya turn the bass up. I like the tone controls on this amp too. They really do, do something when ya twist them. So much so that if ya turn all tone controls to zero, there is no sound out of the amp. Unless ya turn the reverb to max and the master vol to max. Then ya get this washy full reverb sound. Not so useful, but is kinda cool. Iāve not seen other amps that do this.
I also like that I can control the vol. of this amp very well. I get the tones or dirt that I want an near any vol. sounds good quite, sounds good loud.
The prri,
It just has great tone. Closest contenders when I got it was a tone king imperial or the boogie california tweed. Both add another $1000 to the bill though. I never got to play the california tweed, no one had one, but I did play the imperial mkII. Fwiw, I liked the prri better.
The prri has great reverb. I usually set it at 2-3. This is foot switchable which is a win (the supro reverb is not foot switchable, a negative). The prri also has tremolo which is foot switchable. All I can say about that tremolo is wow, itās great and I use it often.
I also like the extreme minimal controls. 2 band eq with works well and Iāve not missed the mid control. There is no extra anything on this amp, and I like that. It is what it is.
I never had a amp w/ a 10āā speaker in it and was skeptical. But Iāve not had issue with the 10āā speaker, though I do think that if ya turn it up real loud, it may become a bit flubby on the bass. Donāt really know though, I aināt never turned it up to the max.
In the end. I like both these amps. They are different flavors. They are both crisp and clean, both can get real dirty. Both work very well in my small house playing by my self. Both are too loud if thatās your thing albeit, from reading, neither are giggable amps if ya do that. I guess they canāt get over a drummer that plays loud. The cure to that is to mic them from what I get.
As for what Iād change if I could. There really aināt anything Iād change. They do what I want. I researched them well I guess prior to buying as I really do like both of them. Guess if I really think about it, I might consider a Supro Amulet as I think itās got tremolo and a power level control. However them two things are not a deal breaker as I really like the tone of the blue king 12. I use a external tremolo pedal with this amp to get my tremolo.
fwiw. From what I understand. A tube amp with 50w and 2 speakers is gonna blow ya away in volume. Food for thought. 50w solid state and 50w tube are two different things. I play a solid state 80w peavey bandit. While itās louder than either of the tube amps, itās not that much louder. All three are too loud so I never get there to try that out.
Good luck in your decision and imho, your heading the right directionā¦
Last comment. While I love my tube amps. I play the solid state bandit a lot durning the day. Reason being is that I think ya can turn a ss amp on and off and on and off as much as ya want. Tube amps, they gotta warm up a few min. prior to playing + I aniāt convinced that tube amps like to be turned on and off multi times a day, especially on/off, on/off all within a hour. Solid state I think works better for this behavior, which I have.
imho, get a tube amp. They are the catās meow. Theyāre dynamic when ya play them. Iād guess your Heritage would sound oh so sweet through a tube amp. Itās what that guitar deserves to be played though. imho.
edit. sorry about the long post. It really is to long. My apology.
) in our well-insulated walls ā¦On the boost channel itās a different cookie, it goes a lot harder, beautiful reverb and a great distortion that can be dialed in without pedals (which I do have of course 
)
