hi, not posted in a while but just got myself a lovely 1978 S300D and wanted to ask if they ever came with black gibson style speed knobs as standard as that's what are on mine. all the ones i've ever seen before either have the G logo dish topped knobs or the taller metal capped ones? not a big deal as the guitar is fantastic but just wondering if i need to source some originals for completeness sake? just giving it a thorough clean and set up but i'll post some pics anon. cheers
