Projects: Maintenance and Repairs
what is a hobby without the joy of maintenance/repairing yourself? In my opinion: Nothing! On this page you find very helpful information on projects, repairs and maintenance I have done so far!

- Steinberger faceplate restoration
- HAZ Labs Active EQ repair
- Replacing worn String Jaws
- there’s more to come…
Steinberger GL/XL use attached faceplates that are interchangeable. I found an offer for a white faceplate with “4” pickup configuration that indeed needed some TLC.
When I bought it, the black speckles were mostly gone, leaving white spots and grey shades that looked very ugly. To get it shiny again, it takes some serious sanding. Before staring, I did some research:
- Faceplates were also molded: The mold was covered with 1.) Mold release lacquer, 2.) Gelcoat, which is the white finish and 3.) with the composite material
- The gelcoat finish is only 0.1-0.2 mm depending of how much has been fine sanded off during production
Starting sanding with 600 grit did nothing at all. So I went down to 240 grit. But be very careful! The gelcoat is very thin and the the logo is just milled through the gelcoat, so the black composite layer is revealed.
You might consider using an open cell sanding grit. Whatever method you choose, go for wet sanding.
HAZ Labs V2 Active EQ repair
All of a sudden, my GL4 created awful noises. Even when plucked very softly, the sound distorted drastically. So I needed to find out why. Amp, cables and the battery in the guitar were fine, so I knew that the culprit must be inside. Watch the video to learn how to search for the root cause and how to repair it!
HAZ Labs was kind enough to help out with information: In case an active EQ board causes problems, it is either the IC (Texas Instruments/National Semiconductor TL072 or LF442 both interchangeable) or one/both golden output capacitors (mine read 4,7uF; 35VDC; 2,5mm). Check the denomination of your components before buying/changing them and buy quality products! The ICs are not produced anymore but you will find NOS items eg on ebay.
Kudos also to Bernd from headless-europe.eu for worthwhile information about how to strategically identify the error!
Metal Fatigue – Replacing worn Jaws and/or Threads
With older guitars, metal fatigue can become a problem. Here’s how to get help when you need a replacement part.
Good as new and ready for the upcoming years!
Additionally, a thread became loose. You need a specialist!
