Tube-pre for recording?

Recommended Posts

I've been recoridng for a while with an audiobox usb and a shure sm 57 and a T-bone large condenser, but I feel the audiobox doesn't have enough gain for the mics, so I was thinking at picking some kind of pre.
Since I had a good experience with my audiobox I was thinking at the presonus tubepre.

Anyone ever used it? I saw there's a v1 and a v2, any differences?

Any other suggestions?

Also, I'm not an expert so sorry if it's a silly question. Once I got a pre, how I hook it up with the recording interface?

The cheaper tube preamps are a gimick. They run the tubes at low voltage and

are nothing like tubes running at 200+ volts. They pass some signal and may add a little

warmth but often add a graininess and noise because the signal passing through the tube is very weak.

The tube does not boost gain. Transistors or op amps do all the work boosting the signal and the tube is

mainly a gimick.

 

The lowest cost tube preamps where the tubes actually do the work in a high voltage design begin around

$300 and up. Anything below is basically a solid state preamp with tube effect for warmth, if you want to call it that.

FMR has one that pretty good and if you want a real tube preamp, I'd start there. Otherwise a good solid state preamp can be

better than those starved voltage tube designs. I have one of these which are pretty nifty. They have about 15 different settings

for different vocals and instruments including limiting which comes in handy. Not super but better than those starved tube jobs

which I also have collecting dust. At least I get some use out of this one for various tracking situations and its very quiet too, not

allot of background noise so they must use a decent quality op amp chip.

Have any examples of high voltage tube preamps WRGKMC? I'm just collecting names.

 

The discontinued Groovetubes "Brick" is the only affordable real tube pre, AFAIK.

 

The FMR RNC is solid-state and would be the entry level for a decent pre.

 

The best bang for buck is a used Sytek MPX-4, which can be had for $600-650 and is 4 channels of really nice preamp, pro all the way.

 

To hook up an external pre, you'd want to set the input on your interface to "line level" and just plug it in.

^^^ Stand corrected mark. I thought the FMR was a tube pre for some reason.

Ive never used one and was only going by what I thought I understood from others.

 

 

Most of your better tube preamps run class A at 300v. Most run $1000 of more.

The Groove Tubs Brick was the only low cost tube pre I could find last time I checked

and ist gain wasnt all that great but it was supposed to have great sound quality.

 

Heres some examples whats out there Beatpoet. It will give you something save up for.

Of course a good preamp isnt going to make a cheap mic sound much better than it would through

a good solid state amp. Sound quality is only as good as the weakest link and a bad tube amp can worse than any

decent SS preamp. Out of this bunch most are very expejnsive. There are probibly more under a grand but I just did a quick search.

The key words are High Voltage 300V and Class A, and more than one tube in most cases. If those items arent in the specs,

its probibly not what you consider a real tube preamp and only uses the single tube for coloration. Its not to say starved circuits

sound bad.

Something like tese would be very cool to build from a kit.

Its cost is 289 Euros which is about $318. Its probibly the cheapest

HV design you can find. Its not a tough build but you have to have good

soldering skills so its not recomended for a beginner. If the solder joints were

solderd cold or the components overheates, it would be nothing but a box of bug.

The Golden age pre73mkii is a very cool Pre and in my opinion sounds much better than anything in it's price range. If you can't

afford an expensive tube pre, it is worth checking out.

The Pre73 is transformer based, which is really more of the 'classic' sound that people rave about on old console pre's (although they often attribute it to tubes, just like in a tube amp, a nice transformer has a HUGE impact on the sonic quality.) It's based on the Rupert Neve 1073 and is purported to have a slightly exaggerated 'color' compared to the original, which is probably what you are going for anyway.

Thanks for that list, though I'll have to forget about saving up and rob me a bank ;)
