hello im just wondering what value yous would put on an 80's hohner the jack 4 string headless bass, ive just bought a new set of rotosound strings for it, the only issue is apparently the active electronics need replacing, it still plays when plugged in though so i was thinking it may only need a battery, sounds awesome, one of the nobs is also missing but thats a cheap fix, i was quoted £30 to fix the lot, the body is in near perfect condition, theres one tiny scratch but the rest is perfect, so yeah basically i just wanted to know what i have here as i got it as inheritance and only new to playing bass, any help would be greatly appreciated, thanks!
