Sound output OK, neck OK, truss rod OK, no scratchiness, with tremolo arm. This is a guitar that appears to be an SG copy from the brand TRUMP. They released the exact same model under the Lyre brand, and since Lyre was a Matsumoku brand for overseas export (there's an English Wikipedia page), I've determined this is also made by Matsumoku. It's likely from around the 1970s, and it's in quite good condition considering its age. It has a tremolo arm. Only the nut has been replaced with a TUSQ, otherwise, it's original. The control section is also original, and surprisingly, there's no scratchiness. Both pickups produce sound properly. The pole piece on the rear pickup seems to be missing one, but this part is originally just a decorative piece and doesn't affect the sound, so it works fine. The neck has truss rod remaining, and it's been set up quite straight, allowing for low action and a thin profile, making it very easy to play. It seems like a user-friendly, "bizarre" guitar.
