Headroom: The Secret of Tone | Low vs High Power Amplifiers

[@ScienceofLoud]

Sell on Reverb and get £10 back after listing your first item: reverb.grsm.io/sell-on-reverb... 100 Watt amps aren't louder than 50 Watt amps, the difference is Headroom which allows them to sound different for the same loudness. Understanding headroom allows you to choose the right amplifier, get the best sound, and do it all at volume levels appropriate for your application.

[@strikebackstudios7592]

does using a power antenuator help when aimng for super high gain structured guitar tones? or is that only a volume leveling tool?

[@midi510]

One of your best instructional videos yet, along with the one on tubes/valves . Something a lot of people don't know is that if you use subs on your PA, by taking some of the load of your mains at their lower end, where the frequencies use the most power, you'll get more headroom on the mains. Even if you don't feel the need for subs, they can make your mains sound better.

[@ElectromagneDikk]

Agreed

[@216trixie]

Very informative !! My example: I gig regularly. Clubs to festival stages. 99% of the time, my 30 or 40 watt tube amp, with a 1 x 12 speaker is more than I ever need. Volume on amp is almost always between 1 and 2. I run my amp louder at home practicing than I ever do on stage. With good PA's now, sound guys/girls don't want stage volume. I get all I need from the monitors.

[@ThrashingBasskill]

Which genre do you play? Because I can tell that you need to at least out-volume the drummer in thrash/death metal, which requires about 50W on Guitars and about 300-500 on Bass. A PA with monitors sometimes does not suffice on smaller stages.

[@216trixie]

I'm in several bands, different genres, though none metal. If you're playing without a PA, then yes, you might need some cranked amps. But any 1/2 way professional gig, from churches, weddings, clubs, on up, almost always has a PA with stage monitors. Mic the cabinet, and you don't need or want much amp/stage volume directly from the amp. Outside of garages, and bedrooms, what I'm saying is most common, in my experience. @@ThrashingBasskill

[@ScienceofLoud]

Playing metal with a drummer does not require at least 50W, this is a myth that needs to stop being perpetuated. I know metal heads feel emasculated when they don't have the largest equipment with the biggest numbers, but it's entirely unnecessary and a problematic mind set to be in.

[@ThrashingBasskill]

@@ScienceofLoud I don't know what it has to do with getting "emasculated ", so please don't charge at me. One of my guitarists ended up with sending a 50W amp back because he could not keep up. But I'm not sure if he didn't get something wrong, he is between novice and advanced player so maybe there was a different problem as well. I myself find 100W tube amps ridiculous for anything (also because I have to help them carry this heavy crap from the van to the venue, wish they would go for a bantamp or kemper)

[@marcosroberto3576]

Hey, great video! Here is a question for a TATA: What is "sag" and "Bias" that I see a lot of people talking? I also see controls for this on amp modeling plugins.

[@colt.thrower]

Not 100% sure but Bias seems to be tied with headroom. Higher biases drive the tubes harder. Lower bias reduces the flow of current to the tubes. Sag refers to the drooping of the power supply voltage in response to large transient signals crossing the headroom threshold.

[@Burnt_Gerbil]

Marcos Roberto - think of biasing an amp like adjusting the “idle” on a car

[@N4ppul4]

Bias changes the maximium headroom on the input side of the tube and so in a sense it also changes the headroom of the amplifier. More in depth: tubes are actually really bad at amplifying cleanly which suprisingly sounds pleasant on human ears, so the negative voltage swing and positive voltage swing is amplified differently. Bias voltage changes that behavior by adjusting the signals "middle point" to either more linear (cold) region of the amplifying curve or to more unlinear (hot), which also means there will be more idle current and tubes lifespan might shorten. I hope I remember those correctly, there has been awhile since I read the Merlins book about designing guitar valve preamplifiers.

[@ElectromagneDikk]

They're terms that relate to tubes and the wonky things that go on when you send electricity through a vacuum tube

[@ElectromagneDikk]

@@colt.thrower kinda right. You have to include that most of the time that sag is because the tubes are failing to be able to drive the signal efficiently so they dip out, but yeah at the same time you can have the same settings and if you have more Headroom it won't matter the same settings on the same tubes will do the same thing because apparently there are stages of tubes and tubes dedicated directly 2 powering the main signal and then other tubes dedicated to tone and possibly preamp volume before the power tubes? I don't know I know a lot about it and I still don't know very much about it. and I've successfully owned like four different tube amps LOL

[@alanst.4417]

As always, your presentation style is fantastically easy to understand. Something that you do that really sets you apart is always sticking to non-ambiguous terms and never accidentally slipping into the slang that is so commonly used.

[@alanbeber6197]

Colin, you've just solved a problem with my Peavey 100W VIP3, when using an acoustic guitar. The power amp would really break up unless I turned the treble right down. Guess the higher frequency transient peaks were too much for it and the FRFR speaker only revealed the problem. So I just put a Compressor in the chain, like you suggested, et voila! The problem never shows using a normal electric guitar, presumably because the frequency response tails off much more than an acoustic. Thanks very much!

[@flamencoprof]

As a person educated in AF electronics by a Government Department in charge of shipping sound around the country i.e The NZ Post Office, which was in charge of telephony in those days, and as a long-time dabbler in guitar playing, I would like to say that this is the best explanation of audio amplification as it relates to level distortion I have ever heard. And, may I add, I didn't watch this vid at random: I find this whole channel admirably informative, and above all, full of succinct factual information without vague references to mythical properties of electronic equipment. That is; just the facts, no shit. Thanks for educating those who don't have an electronics background, I think you do a great job!

1,000 x ...YES! The main reason I got my Laney IRT60H with matched 2x12 cab was for headroom. The options on the IRT60H are insane and lends itself to meticulous tone shaping with just the bare amp...but it is more than capable of being a pedal platform amp (clean channel used exclusively)! Using it in this way is a tunnel vision approach for sure, but it's just damn good with my extensive board and stereo amp setup. When high gain is necessary, I never encounter that annoying squishy fizz. My other amp is a 50W Boss Katana MKII btw

[@jimamsden]

Colin, between you and Uncle Doug, we have everything we need to understand our amplifiers. Thank you for such a clear analysis if average vs. peak power.

[@markhammer643]

As always, and as I have come to expect, a clear, and sensible presentation. Nicely done. The only missing component (though something I'd expect to see from you in a future video) is the power-handling capacity and headroom of the speakers involved. All speakers have a "linear operating range". That is, a zone within which the power applied from the amplifier yields the frequency response depicted in the spec sheet. Anything either below or above that linear operating range may yield something quite different. Going substantially above it yields "speaker breakup" and potentially voice-coil blowout. Worth discussing how maximum power-handling is modified by how many speakers divide up the output power among them, the impact of their wiring on load-impedance and output power, and how this might affect the behaviour of both the amplifier and speaker/s. I would look forward to your thorough common-sense discussion of such matters, and trust you to do a bangup job of it..

[@chuckelator]

Great video Colin! I've always preferred amps in the 30-50 watt range, as I feel they give me the best middle ground between those (sometimes) desirable effects associated with pushing the power amp into over drive, and clean integrity of tone. And its part of the reason I usually run my Mesa Mark IV in half power mode.

[@moustachio334]

The extra headroom keeps the low frequencies nice and full. I had a TH30 that could switch down to 7 watts. At 7 watts it was just as loud but it had much less bass.

[@majkon93]

I'm no expert, but I don't think these power switchings accurately simulate lower wattage. I might be wrong, but I believe that if they made a TH30 with 7 watts in a standard way (using a different output transformer, etc.), it would sound different from your TH30 switched to 7 watts (which they achieve by lowering the voltage, I think). It would be interesting to compare the 'same' amp with power switching to its little brother (like a big 100w switched to 50w vs. a true 50w). My point is that switching from pentode to triode or lowering the volume changes the character of the amp too much to sum it up as just a difference in headroom.

Man... I have a Traynor YCV40 and I've always considered it a 40 watt "clean amp". Then I got a load box and I tried pushing the clean channel over 3. At 4 it gets slightly hairy. At 5-6 it gets hot. At 7-8 it's crunchy as fuck, and at 10 it's basically the distortion channel of a low gain amp. You put an OD through it and it sounds like a very good classic rock amp. The distortion channel, with a boost and the right IR, can very well play some 80s thrash metal. Maybe not the perfect tone, but a very good one. I had that amp for over 15 years, and I've never really gave it the love and recognition it deserves.

Great video Colin ...but there's one part of the power factor that needs to be discussed - Watts does not = "how loud " until the load SPL of how many dB/W is factored in and other limiting load factors like impedance. Headroom can also be killed off when more speakers are added across the output of an amp. Have a speaker system at 78dB/W at 1 mtr will sound quieter than a load that is capable of, say, 112dB/W ....as designers we take this into account.

My other takeaway is this and please correct me if I'm wrong: It's crucial to mic your combos/cabs to a PA vs go Direct to PA from the amp to avoid some of those issues you discussed regarding FR Speakers. Now what about going direct with some of the new amp/cab modeling devices these days? I would imagine that that would work fine since those freq ranges have already been limited in the same fasion as a guitar speaker would.. (perhaps that was one of your points)

[@beornthebear.8220]

The old wattage I used to read was doubling the power adds about 3dB, barely perceptual. Twice the volume is about 10dB, which takes a lot more power.I usually play bass, and I compress and limit the sound. My bass amp is 750 watts run through a vented 1x15 and 4x10 cabin

[@Furegious]

So, the headroom of the amplifier powers the distortion of the peaks eliminating the sag of the peak distortion of the speaker minus the headroom of the amp, amplified by the wattage of the peaks which doesn't magnify the sag whilst creating headroom of the simulation plugins without the need of power of the distortion. Got it. In all seriousness though, great video!

I used to think that lower wattage amps were better for low volume play. After spending many hours with a 100 watt Marshal in a home setting I now disagree with that. I have compared the sound of my 100 watt to the same amp in the 20 watt version and even at whisper volumes the 100w blew the small one away. I think it must be something to do with the larger transformers or maybe I don't like the sound of the power amp distorting. Keep in mind this is a Silver Jubilee and they get most of their gain from the pre-amp like the DSL's and JVM's do. I am sure with a plexi circuit I would like the sound of power amp distortion. I had an old Gibson Skylark 15 watt tube amp from the 60's that was clean tones only. I found that when i cranked the master it had a really smooth distorted sound that I really liked. That tells me in certain cases power amp distortion is good and in others not so much.

Very informative! Easy to understand explanation, thank you

I've got my guitar and my half stack on reverb. Cheers to you! Btw, my 100W head doesnt compare with a vox 30 head... Maybe Marshall is the anwer ;)

i design amps with intentional and variable headroom limiting, this gives a nice, more natural power amp clipping sound instead of preamp clipping, while retaining the low volume levels.

Hedjrem! Brilliant video. Well explained. Thank you!

[@glenn3412]

I love your videos so much, everything is explained so elegantly

[@sgtsimplycrispy7749]

that should be the official reverb ad. thank you.

[@Leggendar]

Great video! I'd like to see more content like this: well explained, focused and info related. Bring it on mate! \m/

Thanks for doing what your doing! It's brilliantly explained and really simple!

on power amp distortion depends on head room of the power section. some amps you get preamp distortion first. then you get distortion creep which the rail to rail of the signal increases the more you overdrive the preamp. most solid state amps use diodes for distortion so they experience smaller distortion creep than tube amps because diodes distort at low voltage. the most gain in op amp solid state amps will be govern by diodes. in a tube amp what really happens when push the power section hard overdriving the phase inverter. Power tubes distortion sound solid stateish because because most tube amps use pentodes for the power tubes . fet transistors closely match pentodes in the way they distort. also another important part of power section distortion is transformer distortion which distorts base on how currant is going through it. I think it play huge role in tube sound.

Really appreciate the timer on the ad part.
