No, it’s not an SG, it’s an SB. This particular bass was only manufactured for 2 model years, features single-coil pickup goodness, on/off toggle switches for both pickups and a bridge cover that’s difficult to locate these days (it’s a rare part).
Does it sound good? As you’ll hear in the video below, yes it does. The singles in this particular Gibson actually have a nice sound to them. Not necessarily a punchy sound but “warm” without sounding too overbearing.
Check out the video below and hear it for yourself. Post a comment and let us know what you think of this Gibson bass.



I’ve always loved SG style guitars/basses. I added a Jazz p/u in bridge position of an EBO, changed everything. This is cool.
I thought all the SB basses had alder bodies and maple necks which is one of the reasons they were a cheaper option.
The neck and body of the Gibson SB 300 and SB 400 are poplar. Same thing with the Gibson SG 100, SG 200, and SG 250. -Jack Clinton Looney, 1902 57th Street, Lubbock, Texas 79412. (806)777-9899. jackclintonlooney@yahoo.com
Love it ,had one great sounding and playing.
I had one back in the 70s. So sorry I sold it.
A friend just gave me an SB 300 yesterday. It needs work to be a player. What bridge would you recommend as a replacement? I’m not worried about the “vintage” aspect. I’ll drill, fill, etc… Whatever it takes to make this a working, gigging bass!
I would absolutely love to know what bridge is on this bass now??? Anyone??? Please???
To be able to upgrade the bridge and keep the cover would be great!!
Was it sold?
I have an SB300 in beautiful condition. I think its from 197I. use it regularly and it sounds really nice.
One of the bridge saddles split so I use a very small block (which can’t be seen under the cover) to keep the string on the saddle. This has not affected the sound or tone quality.
I don’t know if a replacement bridge or suitable alternative might be available.
