I think the issue was that reproducing the recording for domestic listening lost all of those frequencies master tapes cut the low end to preserve the sound for records and radio which could not carry those frequencies very well, or something like that. But, yes recording music was perfected in the 50s, some of the best mics, tube consoles, compressors and limiters were developed truly the golden era of audio refinement, just making that into a product wasn't that good...

@flyingrat4924 ай бұрын
@@geotungz4050spot on, the reason there’s so little low end is because it needs to be cut out, vinyl skips if there’s to much low end which makes the record jittery, so they needed the EQ to remove a lot of it. Vintage mics and pres at that time were more than capable of capturing the whole audible range, it’s just the listening medium of the time wasn’t built for it

I've found that a Pultec plugin ( I happen to use the one from IK Multimedia) across the mix buss with some subtle boosts in both the highs and lows gives a "sheen" to the mix, makes it punch more, and gives more "sparkle" and clarity in the highs without sounding harsh.

My version (Waves Puigtec etc) does very nice things to string busses to both warm up the low end and add some smooth sheen to the V1s up top. Likewise the mid EQ version finds much use with me in de-muddifying overly honky / resonant angry brass sections whilst retaining low end warmth. Definitely a unique EQ, and this video is very helpful for people new to the way it works.

This is a very aptly timed video as Bitwig have just released a stock plugin component-modelled on the EQP-1 ("Sculpt") as part of Bitwig Studio 5.2. I can't say how closely it sounds like the hardware but it has all the right controls (arranged in a much more logical way, too). I had been wondering how on earth you could boost and cut the same band at the same time so this is great to find out, but I'll be trying out that analyser on it to see exactly what's going on and whether the curves look like this so thanks for the tip. As with the Distressor video, this is a top quality explainer and demonstration. It's almost like you're reading my mind as I'm watching it to find out what my next question is going to be and then immediately answering it - very satisfying to learn from!

I've always liked the EQP-1A on hard rock or metal rhythm guitar. Boosting 100 hz to get the power/air moving part of the signal and then boosting 3K or 4K to get the edge out of the guitar. I will usually put a hi pass filter after the pultec to get rid of any mud build up in the sub sonic region. 12db per octave at about 100 hz or so. Also try atten control if the guitar is a little to sizzling or us 6db per octave low pass on the follow up eq. I do agree the UAD version of the plug in is great!

Very cool video, Mike! Thank you very much. I must agree with you that the price of the "real deal" hardware is way over budget for most, including me. I do understand through the rumor mill that the UA engineers did a phenomenal job replicating the original Pultec curves in their plug in version. I don't own the VST, but I did build a pair of retro-style Pultecs from mostly old parts like Spectrasonics 101 preamp cards, UTC oem xfmrs, good caps and hand wound inductors. Got the Q on the inductors where I liked them. Even found some original "telephone switches" surplus for the in/out bypass switch. The switch adds the magic touch as it is silky smooth to operate.To answer you question on using the actual hardware, I like to use them on a master side chain buss. I found that on certain programming the whole track just wakes up with sparkle and personality when blended with the original to my liking. Those are the wow moments. On a master buss I've been able to make the vocals more clear and add a bit more punch on the low end at the same time. The boost/cut trick works really well on kick drums. Thanks again for the refresher coarse , Mike. I'm going to try the Pultec/LA-2A/Pultec trick for sure. Presently I like to record vocals through a tube preamp followed by an LA-2A compressor then into the interface.Maybe I'll try the mic pre into the above trick. Sounds like fun. Take care!

We use the UAD plugin at our studio. I find, the plugin does a respectable job of emulating the Pultec. Having used the hardware, imho the difference is the transformers. The hardware transformer saturation is gorgeous. And then, there is that simple "everything you put through this thing sounds better" thing! While the UAD plugin is really good, the real thing is fantastic. As clones go, Audio-Scape makes a hand-soldered clone which has that "magic." ( a little over 1K US). We do have one of their LA2A clones, 3 rack spaces NOS tubes (they always use NOS tubes fin all of their clones). Fantastic sounding gear.

Pultecs are useful and powerful. You've done a great job of explaining it. LMAO , I remember the 1st time I tried to use one ( I was lost). Theire are plenty good free VST versions of them out there. If anyone uses Reaper and Tukan plugins , you're good to go. Analog Obsession and Ignite amps make good versions too. Ignite Amp has hi/lo pass filters I believe (been awhile sice I used theirs). They are great for adding punchy bass and airy clarity to anything. I don't really like them on vox. But individual drums , Bass Gtr and Rythm GTR , synths, very useful. I usually add hi lo pass filters after a pultec if needed. Great video.

For some reason or pure luck, it solved the problem, and brought something nice to the mix! Thank you for clarifying! Was quiet astonished at the behaviour of the plug-in!

Sorry, on the move here man, but just quickly, the first EQ + the compressor HP filter are combining to make sure the compressor only reacts to mid/high frequencies. If you don't use the HP filter on the compressor, you may end up with artefacts. The final eq is kinda attempting to reset the balance of frequencies. Although I think it's often still nice to leave some hughs there.

I played with the Plugin-Doctor (instead of the Bertom Audio analyser) and noticed the huge difference between a few Pultec emulations.
