That's fantastic, Les! Nothing feels better that a well researched GAS target, acquisition then confirmation that it was the right choice. Congrats.

I have no pearls of wisdom with these new DG amps, directly. TAJ and Aristotle have you well covered.
I'll throw this out there to ponder, though: how close is the 30w DG to any other PRS production/CAD amp? Tonally, to my ears, the 50w version sounded a lot like the Super Dallas (one of DGh's favs) camp (and I meant to ask Doug). Why do I ask? Well, because a lot more mileage is on the Super Dallas than the DG 50 and if they come from the same camp, gear that works well with one might work with the other. Is the input stage of the DG30 similar to the Sweet 16? If so, some of the pedals known to work well might be worth investigating.
Expansion on that thought: the Klon KTR sounded stunningly great on Martysnarf's Sweet 16. Paired with an EP Boost it was impressive. So much so that I recently (as in yesterday) built a Klon Centaur clone for my Super Dallas. It's insanely amazing! Like it was made for the amp. So if that works well with those two amps, one could deduce that it might work well with their (supposed) cousins. Right? So in a very long winded way, I suggest you look at one of the low gain OD pedals out there, especially a Klon variant/clone or similar.
Interesting that you should mention the Klon, and low gain OD pedals.
Before I launch into my Klon and other low gain pedals story, I will take a detour and explain that the only US PRS amps I've ever played through are the HXDA and now the DG. They just don't show up around here at stores I hang out in for whatever reason. And I bought both only after hearing clips on the PRS site, never having heard either in person. So...yeah, I'm a little weird.
OK, now on to my tale of Klon and low gain ODs.
Back around the year 1999 or maybe 2000, the only place you could find boutique pedals in my neck of the woods was a little shop that had mostly vintage gear about an hour's drive from me. I asked the owner, who was a pretty interesting dude, what he had in the way of ODs, and he brought out a gold horsie Klon and a Fulltone Fulldrive. Both were priced around the same at the time, as the Klon was his personal pedal, he'd used it for about a minute and didn't care for it.
So I tried both. Now, understand, I don't like high gain overdrives, I like to get a bit of grit and that's it.
I had never heard of Klon. I had heard of the Fulldrive, because some of my session guys had them. Anyway, he handed me a '65 Strat and plugged me into a very nice sounding tweed Twin, and there we were. The Klon sounded fantastic through the Fender. But we turned the Fulldrive's gain low, and that sounded great, too. Different, but great.
Then he brought out a vintage Marshall Plexi, and the Fulldrive sounded great, the Klon didn't. I knew nothing about this pedal world, but I knew my main Tremoverb was more gainy than the Twin. I felt that the Klon wasn't going to work as well with it. Incidentally, I may have been right, who knows. So I passed on the Klon, and bought the Fulldrive. And the Fulldrive was fantastic with the Tremoverb and the other 3 or 4 Mesas I had on hand at the time.
I set the gain of a Fulldrive very low, by the way. Just enough to give a little push to the edge of breakup. I've had every model of Fulldrive since, and I have had great results. Sounds great with the DG, too.
Of course, I wish I'd gotten the Klon so I could sell it for a couple of grand on ebay, but...WTF.
The new FD3 I have has an interesting boost circuit: clean boost, but you can dial in a germanium transistor circuit that acts as a limiter, and it's beautiful sounding. I also use an Xotic SP compressor, that you can blend the uncompressed signal with the compressed signal any way you like, and then boost it. It's a wonderful circuit.
As an alternative boost, I use a Fulltone Catalyst in "Spark" mode with the gain set low. What that does is both act as an EQ, and clean boost, and when it clips, it's got a nice edge, but not very much distortion. I boost the highs a little and roll off the lows with the built in EQ.
With the volume on the guitar rolled to about 5-6 (my normal playing setting), it makes humbuckers sound as clear and crisp as P-90s, but without the noise. It's a unique and cool little pedal.
Of course, these pedals are all different from a Klon. One of my session guys has one of the later silver Klons, so I should really ask him to bring it over to try with my amp. Then I'll know for sure that's the actual Klon sound, and find out if I really need something similar!
Edit:
On another front, I love reading Bill Finnegan interviews. Here's a guy who is so picky, and so particular, that he can't seem to just be willing to capitalize on the fame of his Klon and make money on it. Instead, he hand built them, couldn't make money, and then licensed the building of them for the KTR, and wasn't happy with the results.
The guitar world has a few of these type of guy, the Alexander Dumbles, the Bill Finnegans, etc. I admire their tenacity, but I dunno, if I'm that guy, I team up with someone who knows how to make a buck, license the building of the product, and get rich.
On a personal note, if I really really wanted that Klon sound, I think I'd pony up and buy an original Klon. After all, you're not buying a pedal, you're buying a sound, and if you want the last nth degree of that sound, seems to me you have to have the original. I'm insane of course, but I've always felt that to pursue something esoteric, you have to have the most esoteric version!
In a recent interview, Finnegan said he still has original gold models that he gives to a lady friend to sell when she needs money, and lets her keep the money. She sells them on ebay for a couple of grand.
I think I'd go that route if I really wanted one. They're not gonna go down in value until Finnegan starts production with the heavy cast models anyway, and that's never going to happen.
