In a screenshot from a 1994 interview, a TASCAM 424 Portastudio can be seen on a shelf, identifiable as the Mk1 model by its 4 tracks. John Frusciante used this recorder to create his entire albums "Niandra LaDes and Usually Just a T-Shirt."

The Tascam 464 is seen in this video about Björk's 1994 studio, starting 0:10

The link lists Jeff Stovall's recording credits for the album "Roman Candle". To see the reference of to use of the 4 track in the liner notes for Roman Candle follow the "more images" link under the album image from the Source/Proof URL link. That particular 4 track was a Tascam Portastudio 424.

he's mentioned this directly before but you can see the 4 track cassette deck here underneath the chase bliss mood

At around 28:44 in this 1997 Wah² Exclusive visit to Ween's home base in New Hope, Pensylvania, Gene and Dean show the audience a myriad of cassettes of mostly unpublished songs which they've made throughout the years. Dean also shows "one of many 4-tracks" they have used to record these songs with. It looks to be an old Tascam 424 Portastudio.

in the fall of 94, jeff returned home to ruston to make his first attempt at recording “on avery island", alone on his 4-track, (which was a tascam 424 portastudio, with sm57, just in case you were wondering) anyway he finished these two songs, and although loving what he had made, decided he needed his friend robert to record with if he were to ever have any hope of completing an entire album (which they proceeded to do, on a fostex A4 reel to reel 4 track)

Tim Bernardes is frequently seen using the TASCAM 424 Portastudio in his work. In particular, the video for "volta" on YouTube showcases this multitrack recorder prominently by his side, highlighting its role in his creative process.

In this interview with Martin Yam Møller, Jonas Bjerre confirms his usage of the original TASCAM Portastudio 424. It was a gift to him from his parents around the age of 14 that he used to record the first Mew demos with.

Mentioned in this December 2020 Sound on Sound interview.

Further remote instruction from Oldfield came when the multi‑instrumentalist appeared on Blue Peter in 1979, in a section filmed showing him multi‑layering, on 24‑track tape, his version of the show’s theme tune. “To then see him on Blue Peter,” Berry says, “where you actually saw him build it track‑by‑track, I had more of an understanding.”

Berry’s sole instrument at the time was a domestic Hammond organ, which his parents had bought him. To emulate Oldfield, he bought a Tascam 424 Portastudio and began layering up his own recordings, using the Hammond’s basic beatbox and feeding its various flute, strings and oboe sounds through cheap guitar effects pedals.
