I'm looking to upgrade to a more stage like stack and amp. I use to rock a "Mark Bass" however I sold it when I found out I was having a kid. Looking to get back into a big rig behind me. What advice can you give? 1x15 and 4x10 what style amp? I've been put of the game for a while. What sounds the best?
I'd suggest getting an 800-watt class D amp. I have a DNA-800 amp that weighs just 4.8-lbs and is also dead quiet if you do any recording, because it has no fan. Great amp, but DNA is closing up shop. I got mine in May 2021 when I ordered it through the DNA Artist Rep. Got a call back that there were none in the factory because they didn't have the necessary parts to complete them, but that David Nordschow had enough parts on hand to build one for me if I could wait a couple of weeks. So I waited and got that. You should be able to find a used one on Reverb or E-bay, but a new one would be a trick. Going price for most good quality 800-watt class D amps is right around $799. Mesa has a number of models and most major manufactures have at least one in that power range.
Then I'd get a good 210 cab. Again, I'm using a DNS-210 by DNA for almost all my gigs. I use them on all indoor gigs because it's a very loud cab and it handles 700-watts rms. It's also super clear, clean, articulate and LOUD. DNA came out with these in 2010 so there's a number of them out there. Original street price was around $869. Used prices are all over the place. If you get a quality 210, you will be able to play small and medium venues with just that 210. When you need to play a large venue or an outdoor venue or music festival, get a second 210 and you'll have a de facto 800-watt 410 which should pretty well handle anything you need.
I went straight to the DNS-410 back in 2015 because I figured it could do everything. The one thing it can't do is small venues. Not because it's not able to, but rolling in a 410 in a small brewpub usually gets a response like, "that's way to much for here. Use my 112 combo instead". I ended up buying an Eden EX-112 cab and like it so much I bought a second one to cover my medium-size venues. The two 112's would handle most large venues too, but I like the sound of my DNS-410 better. I used those 112's for about a year before I got my DNA endorsement in 2019. Then I bought my DNS-210 and it was loud enough for all my indoor venues from small to large.
Really would recommend either buying 1 and then another 210 or 1 and then another 112. Advantages are the modularity of it that allows you to only bring one cab where you only need one and still add a second one when needed. If you take this tack, make sure they are both 8Ω cabs unless you have an amp that will handle a 2Ω minimum load.
Of course since I bought my 410 first and my 210 second, I can stack them together to make a massive looking stack like you are referring too. I've only stacked them up once when I first got my DNS-210 because I wasn't sure it was going to be loud enough. I only had the 210 plugged in because I was using my big Eden amp and it bridges at 800-watts into 8Ω. Would take a second or two to unplug the 210 and plug in the 410, which I knew was more than enough if I needed it. That DNS-210 was more than loud enough on its own so my 410 ended up being an $1100 amp-stand for the evening...looks good stacked though!
