The Stagg comes with an active pre-amp powered by a 9V battery. So far these seem to have eternal life, even when it is of some obscure brand. But I have also read reports online that claim very short battery life. So just to be sure I have put a spare in the gigbag

Electronics-2On both my Staggs the electronics work pretty well. The headphone out is really handy when practicing late at night and the MP3 in is nice for playing along your favourite tracks. The Stagg has two piezos (one under each bridge foot) that have an adjustable potmeter. A small adjustment can have a great effect on the sound so be careful!

The very first thing I did on my black Stagg was shielding the electronics. The Stagg company did not bother with this and it is easily done by yourself. You just need some aluminium or copper tape, a sharp pen knife and some time. I did not think of this myself but found a complete tutorial online: see it for yourself on Flickr. Thanks for sharing your pictures mateybass!

I followed the tutorial picture by picture. I did try the foam under the piezos on the black Stagg but did not hear any difference in sound whatsoever. The endpin rattle I have solved another way. You can read about that here and here.

Below a few pictures of the shielded endpin cavity. The pre-amp cavity looks the same.

  1. Did you notice any reduction of him from the amp after you shielded the cavities? Was it a particular problem before?


    1. To be honest.. I would not know… I applied the shielding just to be sure as I had read from quite a few users that it helped preventing unwanted sounds from the amp.
      My Stagg came with some very basic shielding from the factory so I just improved that.

      But I honestly do not remember if there was a noticeable difference before and after on my particular basses…



  2. Hi again. Following your and Mateybass’s lead, I also shielded the electronics and relieved a significant hum from the amp. Before, the hum was loud enough to be embarrassing amongst acoustic instruments, but now the amp quietly hisses (which is quite normal, I understand).

    I would say that the other refinement suggested by Mateybass of putting a layer of thin foam under the bridge feet (and cutting a groove in the feet for the piezo wires to sit in was also significant in improving tone: it has the effect of isolating the solid-body sound from being amplified (which is ‘clangy’), and allowing more of the string vibration sound through. Result!


  3. Hi Erik,

    I finally got to test a Stagg EDB 3/4 RDL today. I found it to be very well playable, the build looked more than fine, and the sound was acceptable when playing pizzicato through an amp.
    It could use some better strings, especially when bowing, but I knew that from reading reviews and from your very useful blog.


    When I tried playing it with a bow, and through my Sony earplugs, it was really VERY awful.
    The sound was very thin, soft and nasal, especially the higher strings. But the worst part was that it seemed like there was a ton of echo on the sound. One big, blurry mess of sounds.
    Playing with a headphone would have been the main reason for me to buy it, so I was very disappointed.
    Any thoughts about this? Any idea on how to fix it? Is it the headphone amp/output? The combination between the preamp and the 40 Ohm headset? …?

    Best regards,


  4. Hello,
    The bow on the stagg is just… awfull, yes, because of the piezzo design.
    On mine, I have added a Schaller magnetic pickup (with a bit of steel folding) and screwed it at the end of the fingerboard.
    Well… it now sounds… electric, but nice. And, with the help of a Phil Jones Bighead, it is possible to bow while wearing a hadphone, without drilling holes in your eardrums.
