Depth/resonance works in the NFB section of the amp, most 1-5w amps don't have that section (which is why most of them don't have presence control either).
Amps:
Soldano SLO100 x2 | Wizard MC1 & MC2 | Diezel Herbert
Fryette Pittbull CL | Marshall 2203KK | Krank Rev 50 | Mesa Mark 2A

Rack stuff:
VHT/Fryette GP3, GP/DI & 2/90/2 | Peters FSM/Chimera
Verellen Meatsmoke | Synergy SYN1 | Mesa Studio

It increases bass, punch and transients quite a bit. Also volume goes up 15% or so, I love it. I got the schematic from a jet city modder in the states.
Funnily enough my amp has been modded to an AFD marshall with a Plexi switch that drops out a gain stage. 20 watts and it kills man. If you wanted to go down that road I can suss ya something. Its dual channel too.
hmmmm.....please sir, tell me more! which Jet City do you have? did you do the mods yourself? after buying the amp and doing the mods etc. what does it owe you all up ya reckon?

OIC.....so the mod that griff was talking about....does that basically add in a NFB section into the amp? do you know why it is left out of low wattage amps?

Modding a 1W amp is pure madness, and you'll end up with something that doesn't do what you want and no one will want to buy for anything like what it's cost you :(

fair point....i guess the way im looking at it is, i cant do the big amp thing anymore. i want a low watt tube amp, cause ive done the digital thing many times and have come back full circle. it needs to be home/night time/sleeping kids/recording friendly. it also needs to be simple. not too many bells and whistles.

these 1W marshalls and similar low wattage amps from other brands are pretty cheap to begin with. upgrading the OT and tubes is probably a $150 exercise. so even if i sink $600 or so in buying the amp and modding it to be more align with what i like tone and feature wise, to me that is worth it. with this level of investment it is unlikely to be something i would sell anyway. if i wanted a bigger amp down the line i would still keep the small guy too.

just not sure what other options there are for my situation :(

It doesn't "add in" a NFB section, it opens up some controls on the existing NFB. IE not possible if it's not there in the first place.

1-5w amps are usually single-ended and it seems like NFB is rather uncommon on SE designs. You'd have to ask someone more technical minded on exact reasons.

Also any low end increase you have on the amp are still eventually limited by the capability/headroom of the output tubes. You won't get what you want with 1 or 5 watts (or even 20w really).

I'd recommend keeping the Rivera, you're basically chasing your own tail here. Chuck a volume pedal in the loop for night noodling.
