    Speaking as a veteran bass player, a budding amp tech, and a huge SVT fan, this was pretty much the best amp review I have ever seen. You are a treasure.

    • @PsionicAudio
      @PsionicAudio  3 года назад +10

      Wow, thanks Mark.
      You know, at the end of the day, I used to be a gigging musician in the trenches, so I'm always on the side of the player.
      I've seen so many piles of junk get "Editors' Pick" awards, seen so many YT videos selling crap disguised as "reviews" etc.
      So I have to speak out.
      But now at the end of a working day I need to go work on my right hand position on bass, so future videos will have better playing. ;)

      @@PsionicAudio Well, you certainly approach the instrument like a bass player. You can always tell the difference between a guitar player who is playing a bass, and a bass player (not that there isn’t room for all styles).
      As a bass player who repairs guitar amps, I put a lot of effort into understanding how and why certain guitar amps appeal to certain players. I know what I like as a guitar listener, but not being a player, I have to rely on the perspective of real players to really understand less tangible parts. It’s refreshing to see this applied to the bass player’s perspective.
      SVTs are terrifying, and beautiful machines. I really enjoy your channel, and find your work ethic and attention to detail inspiring.

    Ive often said I must have gotten a good one. Bought my VR new in 2010 and its never failed me, nor have I had to replaced the tubes. And it was made n Vietnam. This amp has traveled around the country more than once and used on hundreds of shows nationally and locally. Standby hum? Almost zero. You have to put your ear right on the speaker grill to hear anything at all. Great amp, great tone. And yes, its worth the weight.

  • @kosmicwizard
    @kosmicwizard 3 года назад +6

    Hi Lyle, thank you for this. I really enjoyed the video, as always!
    I own a 1988 SVT ll (non-pro) which is the 4U rack mounted version of the first skunkworks SVTs SLM made when they brought production back to the US from Japan in 87. The line that my amp is part of was replaced by the 2 PRO in 92, and I've heard many people prefer the non-pro model to the later PRO and CL lines. I know part of the reason is because this was the first return to the original 1969 preamp design, while using easy to acquire modern preamp tubes (I.E. 12ax7 and 12au7) instead of 12dw7 and so forth as per the original design, but I wonder (besides for scarcity) is the non-pro more desired for the purity and simplicity of its circuit compared to the later models? What differences did the changes to the 2 PRO make tonally and regarding the schematics that make it less well liked?
    I don't know if I'm the only one or not, but I would love to see you take us on a schematic walkthrough of the "high water" marks of classic bass amp design (like the 69 SVT vs Traynor YBA3A, vs 1987 skunkworks SVT-HD vs 1988-92 SVT ll (non-pro) vs SVT 2 PRO and SVT-CL specs. Can you please do this for us in your spare time? This kind of amp comparison series might take off and make your channel much bigger than it currently is? Who knows, but I honestly can't think of anyone else more qualified than you that I would want to describe the changes and the effects of those changes to classic lines of amps!
    On that note, another iconic line of amps that I am so interested in is the Fender Bassman and Bassman 50 series. In a similar vein as what I just described regarding the SVT, I would love to know revisions (and possible reasons) that Leo made to the tweed 5 (A-F) 6 circuit, why Jim Marshall chose (of all the amps in the world) to base the JTM45 on the 5F6-A circuit, why Pete Traynor did the same thing with his YBA1, why Leo moved on to the brown panel piggyback designs and then to the black panel AA864? Also, why CBS began almost immediately to alter his designs in the AA165 and AB165 circuits, and finally what did they hope to accomplish in going farther away from Leo's AA864 design in their later silverfaced era amps, with such circuits as the AC568, AA270 and so forth?
    Can you think of other all tube amps that made as much of an impact on amplification as these 2 did? Would you be willing to take on such a project? Thanks alot for your time and effort that you put in to making your videos for us! Cheers.

    Modern Ampeg is 'over-engineer', why have diodes going to 6550's? SVT's from 1969 to 1978 are perfect from engineering standpoint. Easy to replace, work on, and debug issues.
    Modern Ampeg's schematic are hard to figure out vs older SVT's. As well as Modern Ampeg are harder to take apart, and troubleshoot. They even leave off from the botton of the printer Circuit boards Rxx or Cxx, Jxx. Have to look at the top and guess where they are on Bottom.
    Another issue, the bias of the 6550, and Hum Bal control... Straight forward on Older SVTs and easy to do and reach those 'Test Points'. The modern no where to be found. No Test Points.
    In summary, like Modern Ampeg but they are not fixable by a Human, They make buy a new amp because it's so hard to troubleshoot and repair. Good for them, not for you. I seen musicians buy serveral Modern to handle this issue instead of repair. With Older you need at most (2) one for play and (1) backup while the other is being repaired. I can go on and on. This what comes to mind quickly.

    Don't waste your money. I did. Things are not what they used to be, trust me, a Chinese circuit board POS is Not worth two grand.
