That guitar type is usually just called a "double-neck". And one of the strengths of Nightwish is that every song IS different.

Simply incredible. Love this performance. Marko killed it and a nice backup singer as well. Loved Troy's low whistle here. Fantastic reaction to our beloved Nightwish. Thank you.

🤗🍒🤘🏻 well done

Marko named his double-neck "the Beast" and it consists of a Warwick bass on top and a Framus six-sting guitar on bottom

stax w the sauce aye 🙏🏽‼️

Recently found your channel and have been catching up on your Nightwish and Marko videos. After about a year away from the music industry, during which he found out he has a form of ADHD, is on medication, is continuing therapy for long-standing depression, and has reordered his music career, he has been touring with his band who you saw in your Dead God's Son reaction. Most recently he has toured with Tarja Turunen, the original lead singer for Nightwish, and their two bands. The link below is for his recently released single, Left on Mars, a love song to his wife, featuring Tarja. I think you'll enjoy it. kzfaq.info/get/bejne/Z7qXhLKbmNjbqnk.htmlsi=OEjghWQ6nRBMrAmP
