    From the “nuts & bolts” department...info to live and die by.

    I just saw this. I learned a lot.
    Maybe it will be worth your while ( or not ).

    Ya, he is really, really good, but I have a very hard time listening to him.

    I enjoy his channel but that thick Scottish accent is tough sometimes. The YouTube CC option helps some.

    Thanks for sharing!

    Instructive but I could have done without the message from "our sponsor".

    Guess we can tell Etsy has taken over and yet to understand how to advertise to musicians. IMHO.....that wasn't it. The information provided visa via Ebay is also inaccurate. Reverb now charges more for the sales of musical gear (5%) than Ebay (3.5%).

    So thank you Reverb but I still believe you sold out those who first made your marketplace viable long ago. It was the private individual seller who got you up off the deck not the major online retailers who eventually took over the majority of the listings acing out smaller sellers in the process not that it wasn't expected when you wanted to sell the place for $275 mil.

    Please don’t lose sight of the main idea of the post.

    It is NOT about the “sponsor”.
    It’s about the technical information.

    It's what their founder does. He made his first pile of millions building and selling an online options trading platform. I was never a believer in the Reverb myth, because they weren't, either.

    Back on track - I always read people talking about "headroom," but in only this case has the person talking actually explained what they were talking about.

    Good stuff -nothing I didnt know. I prefer headroom and pre amp distortion.

    Finally figured that one out after a bit of digging a couple of years ago. So as I posted as soon as the hoards of online dealers became attracted I knew it was only a matter of time before someone would buy him out.

    It was nice while it lasted and I sold quite a few pieces there earning all my badges but the last was a little over three years ago and with their increased fees and policy changes I'm not likely to return soon as a seller.

    On track - He did nail it pretty well didn't he? It would probably come in handy if more people understood the basics of amplification and amp designs and the cause and effect of all of the different components involved.

    Funny thing is, I don't actually find headroom all that needful or desirable, because of the sounds I prefer. But I get where he's coming from, and he gets into specifics instead of just repeating conventional wisdom phrases.

    Sorry, couldn't resist. If was a pretty goofy commercial. :oops:

    And I do feel he did an excellent job out outlining what higher wattage is able to provide and why we have a lesser need for it in current guitar amplification.

    I am by experience more of a bassist so our needs for clean headroom and peak power handling are much different than those of my needs as a guitarist.

    Can you discuss the difference?
    I have never played a Bass, so I find this to be interesting.

    The graphics and explaining how much differing types of amplification for different tasks varies should also help some I would think.

    My needs as a bassist are much different from my needs as a guitarist and PA systems can require massive amount of power and headroom to handle all they're required to.

    It pretty much starts with the need for more wattage and headroom to cleanly amplify lower frequencies and also to deal with the greater transients a bass can produce in a frequency range an octave or more below a guitar.

    Think of it a bit more like drums where a loud kick drum and a snare hit will suck up more wattage and headroom to produce without distortion. Bass is very similar in term of also having a need for more wattage to amplify.

    About the lowest wattage Class D bass amp I could reasonably play in a club without some PA reinforcement is 200-300 watts @ 4 ohms. My main rig is 750w into a 4 ohm cab with two 12" speakers. It can get quite loud.

    In contrast one guitar amp is 15w tube head which I run through one or two 1x12" cabs and can easily handle club gigs and another is 60w analog SS 1x12" combo if I need slightly more clean volume and headroom.

    Does that help at all?

    Here it is in one sentence:

    Headroom is clean signal before clipping, distortion is clipping.

    Best "plain language" explanation I've ever heard. Has cleaned up a lot of ignorance, and bad info that I had floating around in my head. Thanks for posting. P.S., didn't have a problem with his accent. Some Scot's, you need a translator, to understand.:D
