    Wow, great job with those hard-to-replace original MB-Ie and MB-II Aria Pro II pickups!
    I think lot of SB-1000 owners (and SB-600, SB-700, SB-900, Elite I or Elite II as well as Black'n'Gold models (or even TSB) would rather had their pickups repaired by you than get a replacement ones.
    Thanks for this!

      Don't forget the original RSB series! RSB 900, 800 and 600. They also have the same needs, and the original pickups seem to sound better than new replacements, unless you get some of the excellent aftermarket versions: Reed James, Rautia in Finland, or Mr. Armstrong.

    Great video and yes, very much a known fault. I had to replace both MB-II pickups on my 1980 SB-900 (with new MB-IE's from Rautia Guitars, Finland). I've seen the MB-IE "autopsy" post on the TDPRI forum and I wouldn't have thought such a neat repair was possible.

      What was the issue with your pickups? My 1980 TSB-400 has always been noisy so you have to face the quietest direction when recording to avoid the hum. I really need to fix it since I am recording again. I was on a bit of a hiatus since the early 90s, raising a family. 🙂

    First of all let me say I really enjoyed watching this. The overall consensus in Aria pro ii 'world' is that these pickups are impossible to repair. I have the exact same bass that I have owned since I was 18, so for 32 years now. I am lucky the pups on mine are still OK, but I have had a few of these basses with faulty ones, and back in the day there were no exact replacements available, until Armstrong and Rautia began making them. I an trying to do the same job on one of the faulty ones I have here, and it's not easy. The inner part just won't come loose. Nevertheless you showed us all that it can be done, and that is very hopeful, absolutely awesome job, thanks, and greetings from Holland

    • @RobMods
      @RobMods  4 ปีที่แล้ว +1

      Thanks for your kind words. With the other one that I didn't film, something I tried was to put a snug fitting allen key in the screw tubes then pull it like a lever in four directions. There was one or two of those cracking sounds, so I assume this also helped to loosen the epoxy around them.
      I have done this type of thing with one or two other pickups over the years and something I've done in the past was warming the cover slightly, perhaps 40-50 degrees C. Just hot water from the tap or perhaps leaving it in a car in the sun for an hour or two. This makes the cover a little more flexible and less likely to crack.
      Don't be tempted to put the whole pickup with cover in boiling water. ABS plastic will soften and distort at 100C.
      Best of luck with your's!

    • @RobMods
      @RobMods  4 ปีที่แล้ว +1

      PS: Another thing I thought of, but didn't need to try in the end, was to drill out the plastic tubes from underneath. You'd need a drill press with vice, and you'd only take it just to say 2-3mm below the bolt shoulder so from the top, the cover is not effected. Then plug this with blue tack or wax or something when re-potting. Then redrill the bolt holes after the resin has cured.

    Great video Rob, thanks for taking the time to post. I bought my Aria Pro II TSB-400 bass new in 1980 and it's been noisy ever since. Not really an issue live but when recording, you have to stay laser-focused on standing in whatever direction is the quietest which is a major pain since I'd rather be focused on the groove I'm laying down. I have started recording again and would like to fix this issue. My son now builds his own guitars and had a look at it. He said that while they look like the pickups in your video, the ones in my bass are single coil. He showed me where the magnets are using a screwdriver. He tried to rewire it a couple different ways and tried changing out the tone pot but nothing worked. He tried to wire them so they would work together like a humbucker but he said they were both the same polarity so he couldn't make it work. I normally play in the middle switch position with the tone knob all the way up. If I turn the tone knob all the way down, it is quiet. Any suggestions on what to check? I am not against sending the pickups to you if it comes down to that. Could you build a humbucker to fit? I would have emailed you but didn't find any contact info in your About section. Thanks in advance! 😃

    I’ve owned an Aria Pro ll Black ‘n’ Gold bass since 1983.
    Both pickups stopped working sometime during the 90s, so I had them replaced with EMGs.
    Now approaching it’s 40th birthday, the bass is still going strong and plays amazingly well.
    I also own a Stingray but… don’t laugh… I actually prefer gigging with my Aria. Its narrow neck with close string spacing makes it effortless to play and, tone-wise, it does everything I need it to do.
    Your video made me wonder if I should have made more effort to get the original pickups repaired, but I’m content with the sound of the EMGs.
    The Aria may not have the status of a Fender or a MusicMan etc, but it definitely is a great bass. I can’t see me ever parting with mine.

      @stanwellback ปีที่แล้ว

      @@musicmaestrodj sorry… the replacement pickups were fitted so long ago that I can’t remember the technical specs. All I can tell you is the replacement EMGs were slightly smaller than the original Aria pickups, so a piece of black plastic with a cutout was made to frame the pickup to hide the gap. The finish looks more professional than my description would suggest. The EMGs are plain black, rectangular, with EMG stamped in silver (although the silver letters have almost totally worn away over the past thirty years). The bass had a full rewire to accommodate the two new pickups. I’m really sorry I can’t be more helpful, and hope you manage to get your Aria fully functional again.

    Great video. I'm just doing the same thing now but will have to use the silicon mould I made as i damaged the casing trying to get the epoxy out. How many turns did you wind? Also what was the mV reading with the screwdriver as i don't have a good one to compare it to?

    • @RobMods
      @RobMods  ปีที่แล้ว

      I'm afraid i can't remember. This is not one of my basses and it went back its owner after the repair. If I can dig up the original footage I may see something in the extra footage. But really I would have just wound the coil to match the resistance of the others. It is almost certainly 42 gauge wire. As for the mV reading with the screwdriver, well the actual magnitude does not really matter. It's really just whether you get a positive or negative deflection. This way you can tell the phase of the signal. This video "How to Wire Humbuckers" has a bit more info. th-cam.com/video/Sj346vrq5h4/w-d-xo.html

    Fantastic job. These basses, I´ve had at least a dozen, is likely to get broken winding. What I heard it should be because of a little too high tension in the winding in the bottom of the coil. I have had 4 basses with broken coils, nand one with changed out pickup. I have one pickup laying that is broken, and actually I have done very much of what you did but I have not applied the pressure to the corners, so it is still in a box somewhere. I will try that. Thank you for a great video. Oh.. one question... why not just wax pot the coils and fix them to the casing with hot glue? I'm curious as this was what I thought about doing.

    • @RobMods
      @RobMods  4 ปีที่แล้ว +2

      I used resin partly for originality, and partly just because I happened to have some resin and black tinter sitting around. (I ocassionally encapsulate electronics.)
      I have done similar stuff with just a handful of pickups over the years, and honestly the success has been varied. But I've tried to learn from my mistakes.
      These were OK, especially the bridge pickup which I didn't film. It really came apart very easily.
      It is a little strange that they were wrapped with tape TBH, because normally a slow cure resin would be used much the same way as hot wax; to penetrate the windings and reduce microphonics.

    Are these Pickups the MB-I or MB-II?
    Wish I knew about this 10 years ago. IIRC my SB R60's pickup worked in series but only E & A work at the normal volume in Parallel. I'm wondering now if it could have been a not so complicated fix rather than a write off. I ended up getting a custom wound from Reed James, of which I don't remember if he based it off the MB-I, MB-II or MB-IE, or if it uses alnico or ceramic (pretty sure the latter).

    • @RobMods

      Hi mate. I used fibre glass resin which is actually polyester, not epoxy. The black tinter is known as "universal tinter". It is glycol based and is what they use to tint regular water and oil based house paints. Around here, you can buy small anounts from paint shops. FWIW, you can also tint resin with spirit stains and acrylic craft paints.

    You know why becuase you already mentioned earlier, Its resin shrinkage. Also if to much catalyst was used to speed up curing times the shrinkage cause movement which caused strain on the windings. I remember making my own resin casts that too much catalyst would heat the resin and it would buckle, so i think that is the answer, so you knew it already !!!!

      In this case, the epoxy was not really for potting the coils, otherwise they wouldn't have wrapped them in tape, so really, you are right. There's no real reason to re-pot them.

    I have an SB1000 and wondered why you re-epoxied the pickups? Is there a reason they were epoxied in the first place? (i.e. noise reduction or protection). Im not an expert, just wondering if there was a reason for it

    • @RobMods
      @RobMods  4 ปีที่แล้ว +2

      Yep, I think mainly for protection. Although I have since found out these are are well known as prone to failure, so clearly there was a QC problem with soldering the leads wires.
      When wax or resin potting is allowed to permeate the windings this will stop the coils from becoming microphonic, but of course these were wrapped, so that doesn't seem to be a reason. OTOH of course, it is what made it possible to save those three coils!
      As for why I repotted them, well, you are right, I didn't really need to, but thought it would be a nice thing as that's the way they were originally. Oh and I used polyester resin, not epoxy. Cheers!
