Gibson changed the design through the sixties and into the seventies. This era they tried changes to lower production costs & many were not too well received. My 1972 EB-4L used the same basic body & is slightly different than yours. The neck heels evolved quite differently through the years also. [img]https://i.imgur.com/NEhzGqwl.jpg[/img]

My book lists the serial number as either a 70, 71 or 72. With the embossed pickup, I would date it as a 1972. You can remove the back plate and see if you can read any of the pot codes. It should be similar to 1377248. 137=CTS, 72=year manufactured 1972 & 48= week of year manufactured. This will help verify the year. It can’t be any older than the pots.

Thanks. For whatever reason, I limited my amp collecting to this era.........

I believe that they were called HC-12 cabinets. They were a larger cabinet for the GSS-100 amp. I have only seen one before. Here is a shot of my amp with the more common, smaller 2-10 speakers. Over 40 years ago, I had an empty set of these smaller cabinets that had one 12” speaker mounted at a 45 degree angle with a smaller horn or speaker also. They must have had several less common versions. These, along with the GSS-50 combo amp were Gibson’s 2nd attempt at marketing a solid state amp in the middle to late sixties. They had one combo amp in the Crestliner Series.

The Les Paul Signature had a jack in both places. Low Impedance on the bottom & high on the top.

The Shure A95U works well as is, but you need an unbalanced male XLR to 1/4 mono chord to go with it. Hosa makes a chord that I’ve bought in the past. The Les Paul Personal actually has a stereo jack for an output jack. The tip is guitar & the extra contact is for the mic if I recall correctly. Mine came with the same chord that was shipped with the Les Paul Professional, but I’ve seen a part number for a different chord that likely came with some of the Les Paul Personals. I’ve never seen one & all of these original chords are hard to come by. I’ve bought a “Y” chord adapter to split

Must be original! I would imagine without the varitone switch that they left the big choke out also.............

The slotted headstock narrows it down quite a bite. My book says it started late 1969, it didn’t last too many years. A lot of people converted an EB-0 to an EB-3 by adding the second pickup & a toggle switch. I’ve never seen one come from the factory with a toggle switch thought it could have been altered. If you can see one of the pot codes, that will help narrow it down. 1376942 (example), 137=CTS, 69=year pot manufactured & 42=week of year manufactured.

I had never seen one before, (like most people!). I run into one in a local pawn shop. After a while it started to grow on me in an odd way. I went to pick it up and was told that it was just purchased by Beck’s road manager. It was quite a while before I would run into another one that I would eventually buy. Justin Meldal-Johnsen years later sold some of his basses on eBay, his 20/20 was in the lot. I asked another ex Gibson employee (Randy Lenard?) on another forum if he remembered it. He said that it came and went like a flavor of the month without much interest.

The Gibson 20/20 is a very rare bass, designed by Ned Steinberger after Gibson acquired his company. They weren’t very popular & not many were made. Members of “The Last Bass Outpost” blog have discussed this bass in great detail. Several of us own them. We believe that somewhere between 50 & 100 were produced. I think it’s closer to 50. Also, “The Gibson Bass Book” written by a member of the Last Bass Outpost is an excellent source of info on this bass.

Like Dave F said, it lands somewhere between 1970 - 1975. You could pinpoint it a little closer if you could read one of the pot codes with a dental mirror or a WiFi Borescope etc..... Example of a pot code 1377234. 137=CTS (manufacturer), 72=year pot was produced & 34=week of year produced. The 2021 VG Price Guide lists it at 1970-1979 Various colors. Low-$2,600 High-$3,350. Going by that, pinpointing the exact year won’t impact the value between 1970-1975. You can also watch eBay & Reverb to see what they actually sell for. The tuners were changed from the original Klus

I still have my ‘68 12 string. I’m not much of a 12 string guy, but it was too good to pass up at the time. It has nylon saddles.........

I was just on a quest for an L5-S case. The L6-S & L5-S are the same size & use the same case. They don’t pop up often. I was finally able to buy a recent L6-S case on eBay about a year ago. A Les Paul fits in a L6-S case but a L6-S doesn’t fit in a Gibson Les Paul case. I bought a Gator single cut-a-way case for a Les Paul Jr DC Bass. The dimensions were a bit larger on this case than most LP cases. It does fit in this case but it is a bit snug. It should work for a L6-S.

I’ve had the same problem with the 2019 Les Paul JR Tribute DC Bass & Guitar. Also with a newer Gibson case for a 1973 L-5S. In both cases, a 3/4 piece of styrofoam worked perfectly. I bought a pack of (5) 14” X 4’ from Menard’s for about $7, enough to fix about 25 cases......... I tucked a towel under the body of the guitar for a few months, no more!

It looks authentic to me with the exception of the black paint in the “F” holes, I don’t recall seeing that on 335’s. It seems to be one of the last Gibsons to have a decal serial number, that ended in 1977. 06 is correct for the first two numbers on a 1977 decal. The label is correct, the Schallar tuners are time period correct. It looks real to me..........
