AKG P420 - Modified!

Published 2024-06-10
In which I review and then modify the AKG P420 (Perception 420).

This is one massive nerdy video!


CORRECTIONS:
-The mod makes the AKG P420 emulate a VINTAGE U87i. Not the U87ai as I say in this video.

-There are NOT two capsules back-to-back inside the P420, instead it is ONE capsule with back-to-back diaphragms.

-What can I say? I suck at things.

  • Great video! Love it! It sounds excellent on you. Thank you for the shout out and helping to spread the truth about this AKG that "Big Mics" is trying to hide from you. That song should be played at every High School Prom from now on.
  • The background singers really fill in the song when "they' come in. Such a great sound. There also seemed to be an instrument or two I couldn't recognize. Yes, this is something I would do......IF.....I wasn't up to my eyes in other things, and I have a large diaphragm condenser I am already happy with. It's great to see these videos on ways to improve a cheaper mic to get the quality sound we seek. That goes right up my alley with getting the best bang for my buck........or for being cheap. ;)
  • @Ed-davies
    Another awesome video, the cap certainly took the harshness out of the mic, not that the unmodded is bad! The song was epic 😂
  • @DWHarper62
    Actually, I find the P420 to not be as bright as many other "cheap" condensors... But it does sound better...
  • @DearNoobs
    I should probably have a decent mic for my amateur radio setup.. the stock ones are usually a bit 'meh'. i know nothing of mics ... i guess i have to watch ALL the TPS videos now..
  • Wow! That mic is selling for $149? No wonder my used mics aren't selling on FB Marketplace. Will this replace your SE 4400?
  • @jongugin9621
    So glad you did this video. I have a p420 but I was considering switching to the se4400 after the video you did on it. I still think I like sound of the 4400, but this mod definitely improves the p420. Curious to know which you prefer after using them. The modded p420 or se4400?
  • @analog4ever25
    Juicy!! Thanks for sharing. I bought a P420 recently and will try this mod on it. If I'm feeling adventurous, maybe I'll try and dig further into the circuit and see if that low-cut frequency can be made more useful (seems like it might be just a one-resistor change - not totally sure yet) ... What low-cut frequency to target? 120 Hz? 150 Hz?
  • @Myuzu
    Have done same mod with 680pF and then with 470pF cap. 680pF cap removes too much highs for my taste, especially on instruments like piano.
  • @audiofreq
    Samsung seriously just destroyed a historic company. I now hate them with a fiery passion.
  • @badtweed2087
    Ok video. Way too long. Seems that you have an audience for the long so called entertaining blab. For me, I wasn't really entertained, this just wasted my time. But thanks for the info, that part was helpful.
  • @StopSignals
    Sorry dude, I love your videos so much, but today I have to say that there is a big mistake here. Mark worked with a blue mic and it is truly a clone of the U87 because it has a transformer. All blue Perception`s have. However, Perception`s became black P for a reason. Blacks do not have transformers and therefore have a modified circuit. If you want a proper clone - look for the blue full name Perception, not just P. I modified my Perception 120 several years ago and achieved good sound by replacing the capsule with an Octave MK102 capsule.
