In this November 29, 2013 Facebook post, Malmsteen can be seen in an article for Bass Player Magazine, this article reads:

"Swede'N Low As a bassist, Yngwie Malmsteen likes to take it up a notch"

"There may never be a six-string shredder to rival Eighties guitar icon Yngwie Malmsteen. It may not be a surprise to learn, therefore that Malmsteen has also played bass guitar-thank you very much-on most of the albums he's made over the past two decades, including his latest, Unleash the Fury (Universal)."

"I've yet to hear a bassist approach the instrument the way I hear it in my head, so it's easier for me to play the parts on my albums," says Malmsteen. "In classical music the contrabasses and cello parts are integral within the structures of the melodies and counterpoint, and that's how I like to approach my bass parts."

"Malmsteen generally deplores the current state of rock bass, "It's fallen by the wayside," he complains, "It has such a secondary role in rock music, whereas in the Seventies there was a lot more bass playing going on."

"Much as Malmsteen and his neoclassical chops changed people's notions of what is possible on the electric guitar in the Eighties, the Swedish virtuoso has raised the bar on playing bass with his blindingly fast runs and cello-like vibrato. But Yngwie Malmsteen maintains that he never resorts to flash for it's own sake."

"I play very fast on the bass only when a song calls for it," he says. "I don't always play a million notes a bar. I let the guitar do that." --Joe Lalaina

Through word of mouth according to Peter steeles bass tech he used these for the first maybe second album and some shows around those,and could've used these for Carnivore,he supposedly used 50-110s extra medium strings to keep u with the low tuning and if it was used in carnivore then fast playing

In this article Mike Inez says he uses Strings Dean Markley Blue Steel (.050–.105)

In this 1999 advertisement for Dean Markley bass strings, Anthony states:

"I demand a big punchy sound on stage. With Dean Markley I get just that and then some."

At the bottom of the advertisement, we can see two packs of strings. One is a DM Blue Steel Bass set, and the other is a DM SR2000 5-String Bass set.

Zeta Bosio is known to use Dean Markley Blue Steel Bass Strings, as evidenced by photographs of his bass guitars where the distinctive light blue silk of these strings can be clearly seen.
