Hi Linda,
My comment is outside the box from others.
I āpersonallyā want to play guitar.
While I like different tone effects. I want to play guitar, not chase the next new deley, reverb, distortion tone.
Any of the amps I have would be good and meet your criteria sans the āādownload and explore presetsāā as none of them have that capability.
What they do do is sound good from lower than bedroom volume up to way to loud. Two of my amps are likely questionable for gigging though. Probably close, but may not be loud enough.
So, the amps Iām recommending are.
-Fender princeton reverb reissue. Only 12w (7 tubes) so may not be giggable, but is still to loud sitting next to it. It has no features at all other than reverb and tremolo, both are stellar sounding.
-Iām also very satisfied with my Supro blues king 12, now known as a delta king12. Itās only 15w (2 tubes), so again, may not be giggable, but is way to loud if ya turn it up while at home. It has a couple of switches for distortion, and boost. Itās a master volume amp which I like a lot as I can get much distortion at below bedroom levels, if thatās what I want, which I donāt usually want.
-Lastly a old peavey red stripe bandit. Old tech. But itās tones are stellar. It also has a couple distortion switches on it. Since itās a 2 channel amp, I use the clean channel. Itās a 80w solid state amp and this one is likely giggable, it will move your pant legs if your sitting in front of it. Itās plain loud and will rattle windows. It also goes down to bedroom vol. when ya set the vol. low, like 1-2. Still sound great though.
The prri is very pricey and all tube. 1500 new
The blues king 12 is mildly pricey, and while billed as a tube amp, I think perhaps it combines some solid state (the overdrive switches) and the tubes. $700 new.
The red stripe bandits are obsolete, so ya gotta find one used somewhere. They seem to be in the $250-$300 range generally. Bandits come in different flavors, teal strip, red stripe, silver stripe, the new one, cyclops. All good amps, but the red stripe one seems to be most sought after. I also like the silver stripe one which I also have but donāt use much since I like the red stripe one a shade better.
prri and blues king 12 are portable and weight in @ about 30lbs.
bandits are heavy @ about 50lbs and that one I donāt move about so much. The others I move occasionally.
This is just food for thought for you.
Sounds like ya want a modeler to me.
If I were going down that road and wanted all them features to be downloaded and explored. I suppose āmyselfā, Iād be lookin at that new katana 100. Seems like a respectable amp that many enjoy.
Just wanted to give ya that food for thought for just a plain amp that mostly just sound good and amplify, but thatās about itā¦ They suit my needs, but may not suit others needs. ymmv
Good luck in your decision.
ā¦ Here in the Netherlands they are also often for sale second-hand - for people who especially grow out of the smallest versionā¦ you can easily resell it yourself without having to spend a lot of money on a second-hand when wanting a up grade
