So this is how I change away from “New Member”
Anyone have an insight into the difference in tone between the two amps? Is it just overhead or is there something more?
Thanks.

Glad I’m not the only one with that sense of humor here.About DG20.
Sorry.
Les,They're fundamentally different beasts in some ways, and similar in others..
One key difference between the two amps is that the Master Volume on the DG30 is pre-phase inverter, and that on the DG50 is post-phase inverter. Why does this matter?
A pre-phase inverter Master Volume control not only affects the output stage of the amp, it also affects preamp gain; where the post-phase inverter MV operates more like the MVs you find on most amps, like Mesas, etc.
So with the DG30 you might have to adjust the gain and tone controls after setting the Master to get your tone right. On the plus side, it's a bit more tweakable in some ways.
The DG30 has a top cut control, like an AC30. This lets you get very tweaky with your higher frequencies, because you can, for example, boost treble and/or presence, and use the cut control to further shape the tone. The net effect is like using both the boost and cut controls on a vintage Pultec EQ, where you can create different kinds of response curves using boost and cut (and why an EQ designed in the 1950s in good condition goes for $10-20k.
The boost/normal on the DG30 selects a different voltage division in an important gain stage. It kind of reminds me of having two slightly different amps, one more badass than the other already badass amp. There's also a presence control.
The DG50 doesn't have presence, top cut, or boost/normal controls or switches. It has two rectifier tubes, where the DG30 hasn't got a tube rectifier.
The 50 might be a little more toward Marshall, but like the 30, it's still got the tone stack similar to Grissom's HiWatt, if memory serves. You might want to check with PRS on that.
So, to recap:
The 50 is the more 'turn it on and do your usual thing' amp. The DG30 takes a little more time and does a different thing. At first, I was Unfrozen Cave Man Guitar Player with the DG30, and it took me a little while to figure out. Once I 'grokked' the amp, it became, "How did I ever live without this?"
4 EL34s in a 50w amp?here's the 50
No, it’s pretty much just you. The rest of us take this place pretty seriously!Glad I’m not the only one with that sense of humor here.
Thanks for posting this!the DG30 uses a 5AR4 rectifier. this is from the PRS site
I believe that like the DG30, it's cathode biased, resulting in a lower output. Similar to a Bad Cat Hot Cat 30, which uses two EL34s but only puts out 30W.4 EL34s in a 50w amp?
That’s a little different.
Are you saying you wish you had the DG50 instead of your DG30, or have them both?I should add that I should have gotten a DG50 when they were available new. They're cool amps. I didn't because I had the HXDA.
Both. The DG30 is a total keeper.Are you saying you wish you had the DG50 instead of your DG30, or have them both?
Crazy stuff.I believe that like the DG30, it's cathode biased, resulting in a lower output. Similar to a Bad Cat Hot Cat 30, which uses two EL34s but only puts out 30W.
Cathode biased amps (sometimes mis-named Class A, which is often a different thing) are less efficient than the other types, like more typical ABs. They have a different sound, too.Crazy stuff.
My Fryette Sig:X has 2 KT88 power tubes and is 100w. Their Deliverance 100w runs on 4 KT88 power tubes.
