That’s killer Doug! That Dallas looks so good atop your great work.
Ok, I guess I wasn't clear, apologies!
I "thought" I had 2 each of Blues, Greenback, and V30s, but my math (or memory) was bad. What I had was 2 each Blues and V30s, but only one Greenback. I decided the plan was to put 2 V30s and 2 Greenbacks in this cab, and change the Orange 2x12 clone to 2x Blues.
BUT
I guess I only have one Greenback, b/c that's all I could find today! So, temporarily (until the 2nd Greenback gets here), I'm going with this setup, but I'll swap out the Blue soon:
So, here are the before and after looks at the setup:
THAT looks great, and the speaker combo is interesting.That 4x12 just looks so right!
I would think anywhere that makes signs, or banners could do it. Know anyone with a 3D printer?

Just be careful to remember that you have a 15 watt speaker in there.
Also, didn't see the ratings on the speakers, but assuming you are wiring it series/parallel?
V30s are 60 watts, so you're still limited by the greenbacks, just not to 15 watts. I'm not sure what the standard 1960A wiring is, or what ohms your speakers are.That's what I was thinking of last night. At first I was leaning towards a CNC or Laser etching machine, but now I'm thinking about a 3D printer. A friend has one, but I haven't even started looking at what the design software looks like.
Thanks! TBH, the main reason I decided on a V30 / Greenback pairing was so that I could NOT be 15w limited. Amazon says the 2nd Greenback will be here tomorrow.
Yup, with the change they'll all be 25 & 30w, so I'll stick to the standard 1960A wiring plan.
I’ve seen 16 ohm speakers (parallel-series) but 4 ohm (series-series) can be used too for a final cab impedance of 16 ohms, which is normal for Marshall.V30s are 60 watts, so you're still limited by the greenbacks, just not to 15 watts.

OK, I knew the standard Marshall 4x was 16 ohm. Obviously there are two ways it could end up there, so I didn’t know which. And that’s why I mentioned what ohm rating the speakers were, which I never did see an answer for.I’ve seen 16 ohm speakers (parallel-series) but 4 ohm (series-series) can be used too for a final cab impedance of 16 ohms, which is normal for Marshall.

No, I'm sorry, I meant I didn't ever see an answer to what all of Doug's speakers were rated, so I didn't know which way he'd need to wire them.Sorry...
They're typically 16 ohm to my knowledge. I’ve torn apart a few and that’s what I saw. It doesn’t mean that there could be other configs, but that’s my experience. Marshall wasn’t known for inconsistency in their cabs.
Now to fire it up and see if my old ears can notice a difference...
You’re a young guy! My ears are the ones that’re old!
Gorgeous! I wasn’t fortunate enough to find a paisley head like you, so glitz up! A little tip/ Dallas is a beast with bass and at gig volume, you will rattle the tubes and make filament noise. Setting head on the floor will isolate it enough to prevent that problem.
Lol, it's all relative!
I still have the two different hearing tests I did, entering the military (20 y/o) and exiting (32). I can see HUGE differences in them, and that was > 15 yrs ago!
That being said: I have a ton of hum/buzz that just isn't going away. I tried a couple of different heads, and it seems that the common denominator is the Dallas.
Anyone have any ideas on where to start to quiet it back down? I've heard they're normally super quiet...
They are normally quiet. The place to begin is to disconnect everything from the head except the speaker, and see if it’s noisy on its own, no guitar, no pedals, no switching system, etc.
If it’s not noisy on its own, the culprit is a ground loop somewhere. If noisy on its own, the most common issue would be a tube.
It’s a process of elimination.
You really need to inspect your existing tubes. If they are all stock, it’s probably a tube cocktail that struck the fancy of the PRS employee at the time. Mine has different power tubes from yours, but the exact make and model will tell you what they pursued, tone-wise. I took pictures of mine when I pulled them out to help me maintain the great vibe. Each tube was specifically chosen for its influence in the chain. It was very deliberate.Ok, thanks, I'll try that tonight.
If it's a tube, is there somewhere that I can figure out the OEM tubes of a Dallas?
Also, I was doing some research and came across "Bias". Don't fully understand that yet...
