Sunn 1970 2000s

Sign in to disble this ad
Does anyone have any experience with a Sunn 1970 2000s? I have an opportunity to check one out that is for sale, but it's about a 2 hour drive. Iv'e heard good things about Sunn and one of my favorite players (Dan Briggs) says he really likes his 300t. I'm playing an Ampeg svt 4pro right now. But this seems like it would be really cool to have even though I might have to sell my Ampeg to be able to afford it.

I have and have had several 2000S's. IMO tonally they sound tremendous, but they are an entirely different animal from a 300T.
The 300T is a rebadged mass produced PCB Fender amp and the 2000S is a "true Sunn"; a hand wired Dynaco based amp. The 300T is more powerful and sophisticated while the 2000S is basically a Hi-Fi amp, a more simple basic circuit.
I don't think one or the other is inherently better or worse, but they are different.
Probably the most obvious difference besides the basic tone stack of the 2000S vs. the sophisticated tonal shaping capability of the 300T is the power; a 2000S is rated at about half the power of the 300T.

That said, with the proper cab(s) a 2000S is plenty strong, in fact it can get thunderously loud, and personally I prefer a healthy 2000S rig to just about anything else for live work, although a complete 2000S can be somewhat cumbersome to schlep around;



The 2000S amp will work well and get loud with an efficient cab, are easy to maintain and get a nice pure, just “good” tone, but it is a 40 year old amp using 40 year old technology. Most players that play them seem to like them, but they can take a little technique finesse as they are pretty touch sensitive and react to what you input; not really unlike vintage and current boutique guitar amps you can go from clean to snarly just by "digging in" a little.
The amp really has its own character and becomes part of the instrument rather than just a device to amplify the instrument; whether that is a good thing or bad thing depends on the player.

Great reply from edbass. +1 for everything, especially about the 2000S being big, heavy, and 40 years old! This is definitely not a 300T, and could be a big surprise to someone used to a modern solid state amp. The 2000S could also get considerably expensive if it needs any significant maintenance.

Personally I'd keep your current amp if you like it and only buy the 2000S if you can afford to have it as a 2nd amp.

These were great amps in their day, but I wouldn't want to move one around now or have to deal with its upkeep.

Good luck!

the 2000s will amaze you if you have some 15s and a passive vintage bass ime, the only reason i got rid of mine in 2000 was because i bought it for 125 bucks in 97 and didn't think it would be worth exponentially more when i started playing again 2 years ago

There is no arguing about the bulk, even without the massive cabs the 30" wide head by itself is an awkward size and maybe 60 lbs. or so.
However, the maintenance and upkeep is so minimal that it's nearly insignificant. My SMPS power amps and current generation high end SR gear need more upkeep than my old 2000S's do.

The only really expensive components are the transformers and that old Dynaco iron is pretty much bulletproof.
Even the power tubes last a long time; most likely a side effect of using four KT88's to only produce 120-150 watts, filter caps are cheap and last a decade or two.
The 2000S rig I pictured had output tubes in 1999-2000, I grounded the chassis and did a cap job maybe 5 yrs ago, and everything else is 40 years old.
She's dead silent with no signal, strong as a mule, and sounds freekin' fantastic; particularly through a pair of behemoth, JBL loaded 2000S cabs.
Granted I only gig her a handful of times a year, but I'm not shy when it comes to cranking her up and I'll betcha it will be many years before I spend another dime on her!

Most importantly is that the eyelet board/PTP construction is easy to work on. You can repair these amps forever; the dumpster is never the best option after failure as it can be with some modern transistor PCB amps.


Even though it’s substantially lighter than the 300T, a 2000S is most certainly is a bear to lug around though!

Only 60 pounds? Even though I sold my 2000s back around 1984, I still remember it pulling my arm out of my shoulder socket.

That's a guess, I based it on the fact it weighs about the same as the Reeves C225. When I carry both of them I'm more or less "balanced" when I walk.

Of course the longer, thinner 2000S is the one more prone to smashing into door jambs or whacking you in the knees...

I've had both and they are very different....and both are worlds different than the SVT-4 pro. Good stuff noted above....volume and tone really depends on the cabs used as much as anything. If you are running old 2x15 cabs the 2000s kills but it doesn't seem to like higher powered modern cabs as much. The 300T just has brute force power, you want some healthy speakers for it at high volumes. Also, the 2000s has a great power tube grind at maybe 7 on the volume, the 300T stays clean way, way up. The 300T does have a preamp drive channel for lower volume use but it's not the same tonally as the 2000s OD. Also the 2000s will have no frills at all, just a few basic knobs...mine didn't even have a 1/4" preamp out, haha.

A 2000S in good working order could be a wonderful thing. However one that has not been well maintained or has been neglected could be a fairly expensive restoration project when labor, tubes, filter caps, etc. are added up. Just something that needs to be considered when buying a vintage amp.
