Sound OK, Neck OK, Truss Rod OK, No crackling This is a guitar that appears to be an SG copy from the brand TRUMP. It's believed to have been produced around the 1970s, and considering its age, it's in quite good condition. It also has a tremolo arm. TRUMP is a brand seen on some basses, etc., but the manufacturer is unknown. It feels like it might be Matsumoku... They seem to have produced the same guitar under the brand "Lyle." Only the nut has been replaced with TUSQ, otherwise, it's original. The control section is also original, and surprisingly, there's no crackling. Both pickups produce sound properly. The pole piece on the rear pickup seems to be missing one, but this part is originally a non-functional decorative piece, so it doesn't affect the sound. The neck has truss rod remaining, and it has been straightened quite a bit, allowing for low action and a thin profile, making it very easy to play. It seems to be an easy-to-use, vintage-style guitar.
