NAD - Soldano Astro 20

After all the hemming and hawing, I found a used Astro 20 and took the plunge.

I received the amp 1 day before a gig. I re-tubed the entire amp - which I always do with used gear - and spent maybe 20 minutes quickly dialing it in and adjusting the settings with the software. Took it to the gig and it was bliss. I used 2 - 8 ohm 2x12 cabs and the amp had no issue with keeping up with the rest of the band. As it turns out, you wind up with 4 channels at the end, or at least 4 different levels of gain. I hadn't yet changed any of the stock IRs and still this amp blew me away.

For total transparency, I have never played a REAL Soldano. I do have the SLO module with my Syn 30 head and I adore how that amp sounds. The Astro does all those same tones and more. I initially did wonder about the output volume level. My Badlander 25 seemed to be quite a bit louder. Still, the overall impression was perfect for me. To me, the Astro sounded extremely similar to my Synergy with the SLO module but it is a bit more refined, for lack of a better way to describe sound.

Since that first gig, I have spent substantially more time with the amp. I loaded 2 IRs that I prefer to use, but I still keep the stock 2x12 EVM IRs in place for the 2 lowest gain modes I use. I also figured out my false volume perception. The stock 3 channels have an independent level control - similar to what some Mesa amps have. All I needed to do was push those volumes up, and I found that scorch and punch I thought I was missing.

Another great plus to the Astro (for me at least) is the ability to use the head without a cab at all. So, if my band plays in venues that require totally or near silent stage volumes, not a problem at all. And, I don't have to use my Captor X, so one less piece of gear on stage.

As technically advanced as this tube amp is, it responds just as any tube amp should. I have experienced some amps feeling and sounding "plastic" after a bit. With the Astro, the feel is there, the tone is there in spades, and the flexibility is amazing.

For the past several years, I have mainly used my Kemper Stage for indoor gigs. Then I play Amp Roulette for outdoor venues. This Astro is challenging that battle plan. I will likely use the Astro explicitly for a while.
 
Congrats on the Astro! Glad it's working out. :rawk

I'd still love to try one at some point.
 
I know some are concerned about this amp using 6V6 in the power section. I can tell you from first hand experience, there was no "mushiness" when cranked. I often prefer 6V6s in my TC50 as well. Just a different flavor, most noticeable with clean and pushed clean tones. Crunch to full grind, no massive changes to my ears. For the Astro, I used TAD Redbase 6V6 tubes. In my TC50, I have some NOS Russian military 6V6 tubes. Both amps scream, but just a little "quieter."
 
I scooped a distress sale and got a great deal on a 4 month old Astro. I switch all the tubes to Tungsols and the PI to a 5751.
I love all 4 channels, but particularly the clean, blue, and purple channels. I'm driving a single 12 cab w/Celestion E50. The red channel is immense, but I don't often use that much gain.

Been though 2 gigs and lots of practice sessions. This little amp just kills! Now that I have the IRs I want to use....pure heaven. My Kemper will be collecting dust for a while.
 
I have a Nano Cortex and a Capture X coming in. I going to put

through the paces and get some captures done.

How does it compare to the SLO30? :unsure:
I think it sounds just as good and definitely more versatile. Does the classic gain levels better but can get as gainy as I’d ever want and maybe I little less loud? If I need it louder I’ll use the Power Station but so far I think it’s a great amp for gigs I will be doing. True test is always rehearsal so I’ll check that out on Monday when we practice.

Seems like a fun at home amp.
Get all cozy,add some Jet Fuel Gelato to the mix
-start crunching the f**k out, programming tones of the last thing you just thought of, find the right cabinet & speaker match for the moment..
-drive it like you stole it!
I want one!
 
I’m really liking this amp and set up with midi and being able to load it down. This with my Helix for a pedal board will be a great rig for the new band I’m in.
 
Hello guys.

I'm new here.. I owned a JCM800 2203 which I loved but could never enjoy it at home... I sold it to fund my Soldano Astro 20... And it was the perfect decision for home use... I joined a band right when I got the Soldano... The Astro 20 sounds absolutely amazing at home with my ENGL 2x12 V30. I took it to the rehearsal studio and used a Mesa 2x12. The other guitar player brought his 70s Plexi 50w and connected to a 4x12 Orange cab. His sound was huge compared to mine and even though at same volume levels you could hear him clearer. I tried to dial in the tone on the Astro but no matter what I did it was underwhelming, thin and definitely not enough even when cranked... The next time we tried a different rehearsal room which has two Marshall AVT 100w heads with 4x12 cabs. The other guitar player did not bring his Plexi and used the 100w Marshall AVT. I was sure the Soldano would scream through a 4x12. The results were exactly the same. Even without the vintage Plexi, the 100w AVT pushed through the mix a lot clearer than the Astro which sadly led me to the decision to stop taking it with me to band rehearsals and enjoy it at home. I am kind of disappointed to be honest because I thought this amp could do everything. But like there is no replacement for displacement in cars probably there's no substitute for Watts.

Would love to hear your take on all this.

My first thought is you must be playing at extreme volume levels.
Second thought is, if you have plugged into the wrong speaker taps for the proper cab ohm rating you might be leaving power ‘untapped’?

On the other hand, if it truly is underpowered, you have the option to send line out to a floor wedge to add to the output and see if that gets you where you need to be. In a band where the stage sound is high SPL you likely all ready have monitors in use to compensate for the volume disparity ‘mix’.

Thanks for your reply.

Actually we do not play loud enough for my tastes. The mix is very "pop music" , the vocals are louder than everything. My master vol was around noon and so were the two volumes with the second one a little bit higher for the lead channel.

I check cab Ohm rating myself before plugging in and so does the studio employee.

It's not like you can't hear the Soldano like it's underpowered or something. What you hear is a mushy mid without low end (even with the depth switch on). It's not missing volume but headroom. I have not tried plugging straight into a mix console.
