I don't see why not. I'm still running the flat wounds on mine, but I wouldn't hesitate to change them. Gibson just thought that the flat wounds would add a unique character to this model. Let us know how you like the sound after you change them.

I was thinking that the extra pickup was a Roland Synth pickup also. Looks like it may have been modified......

For safety reasons, the tours were all given at the Memphis facility. They sold it & moved out about last April & are still getting tooled up to produce ES Models in various Nashville plants. It may take a while to get set up for tours if they still plan on giving them. I'm sure getting guitars back in production is their top priority.

I would think that all of the Kalamazoo made Epiphones should have the same body shape as their Gibson counterparts. They were made side by side in the Gibson factory until 1969 when Epiphone production was farmed out to a factory in Japan.

Reverb has one listed, I believe the seller is from Canada. It's priced way high, must be why it hasn't sold in three years. You could shoot him a fair offer & see if he's ready to sell. I have one in Bourbon Burst. I'm glad I bit the bullet while they were available, great guitars! https://reverb.com/item/3267074-gibson-memphis-2016-es-les-paul-ltd-pelham-blue

They usually machine away a lot of the center block for electronics installation under the pickups. Some years might be more than others. My Les Paul Signature from 1974 has a "T" shaped center block. Totally hollow on the end by the strap button. Gibson must have reissued the walnut 335 recently...…. http://legacy.gibson.com/Products/Electric-Guitars/2017/Memphis/ES-335-1970s-Walnut.aspx

It looks to be an early 70's 335. I can see the 70's sticker through the "F" hole. It has a stamped serial # which dates it before 1975 when they switched to an oval decal for about three years. It also has the "Made in USA" stamp & volute nudging it into the 70's. It looks like the tuners were changed to a newer, similar style tuner. I would take a guess at 1971, but it's just a guess. Many 1972's had Gibson embossed pickups, but I'm not sure if they ever sold ES-335s with them. If they did, that could rule out 1972. PS..... Here is a 1972.... https://reverb.com/item/25450727-gibson-es-335-tdw-1972-walnut

If it was an L5, "L5" would likely be engraved in the tailpiece...……. https://reverb.com/item/26762412-genuine-vintage-gibson-l-5-archtop-tailpiece-l5-l-5ces-l-5c

Reverb has a few ES-175's https://reverb.com/p/gibson-es-175-figured-vintage-sunburst-2016

Just a side note, you will need an "unbalanced" cable to go with it. I found this one at Sweetwater, but it is only 5 foot long. Mine is a Hosa cable also but longer. https://www.sweetwater.com/store/detail/PXF105--hosa-pxf105-5-foot?mrkgcl=28&mrkgadid=3308752981&rkg_id=0&product_id=PXF105&campaigntype=shopping&campaign=aaShopping+-+SKU+-+Accessories&adgroup=Cables+-+Hosa+-+pxf105&placement=google&adpos=1o5&creative=290335234793&device=c&matchtype=&network=g&gclid=Cj0KCQjws7TqBRDgARIsAAHLHP6s88rgwsAOrhnbg9j7HsRUizwe1Ez1OgU_HrkZIeaxSrMGrro9oU0aAjqeEALw_wcB

You can buy a Sure A95U at many retailers. It is the closest transformer available to the original. Keeping the transformer close to the amp gives you the best results. https://www.americanmusical.com/Item--i-SHU-A95U?src=Y0802G00SRCHCAPN&adpos=1o5&scid=scplpSHU+A95U&sc_intid=SHU+A95U&gclid=Cj0KCQjws7TqBRDgARIsAAHLHP7uL3x5laFbdaIpPs8OfoHkQtZZ3WjyrT3dZFrCMMG6TEfrnThYQKAaAgdnEALw_wcB I watched eBay for many years to find an original, they are rarer than Hen's Teeth!

Musicians Friend & other retailers sell a Gibson Les Paul case for $199. If you get the right guy on the phone, he might let you use a coupon on it. It says Gibson Gear on the photo but in reality it doesn't. Ebay has several used cases, but I didn't see one for less than $189. I'd buy the new one if it were me unless there was much more savings. They are made by TLK if you want to find an unbranded case...….

It's been for sale about 8 months...………….

It does look to be a highly modified SB-350. If it is a long scale, it's a SB-450. The hardware has been changed from chrome to black. It was likely refinished. I don't think that Gibson used that stop tailpiece on any bass until 2011. They were made between 1972 & 1974.
