Elias Jungqvist

Jungvist uses a Korg MS-20 with Viagra Boys, clearly seen in the photo. He also confirms it in an article in Synth History: "Live I use the Korg MS-20 DIY kit(...). The MS-20, ohhh... I love the sound of the high-pass and the low-pass filter, preferably Rev-2. I think it’s brilliant both for flutey melodies and for aggressive sounds. It’s great with the patch panel to patch in another noise oscillator or whatever. The MS-20 is truly my favorite synth, I've played it countless of hours. That’s the main reason it’s my favorite I guess. I've learned to control it well, so it sounds the way I want it to sound in my head." https://www.synthhistory.com/post/three-q-s-w-elias-jungqvist-of-viagra-boys-behind-the-video-troglodyte

In an article with Synth History, Junqvist says: "Live I use the Korg MS-20 DIY kit and the Behringer copy of the SH-101, the MS-1. I think The MS-1 is perfect for short plinky-plonky sounds. I like that it sounds a little bit plastic. It’s also perfect with the built-in sequencer, which I use on a few songs. Maybe the main reason is... to transform it into a keytar [laughs]. Can’t resist picking it up on some song."
