Muhammed Suiçmez

Muhammed Suiçmez is advertised as an endorsed artist for the Engl Fireball 100-Watt Tube Guitar Amp Head, as noted in a tweet referencing his connection to the brand.

Can be seen using these cabs live.

Muhammed stands with his Ibanez LACS 7 string Falchion guitar and a stack of ENGL heads. The Powerball II can be seen on the top.

Can be seen using these in live performance.

In this article, it lists a lot of his gear. The Vader cabs being one of the things mentioned. There are also plenty of videos of him playing live with his Vader 4x12 cabs visible.

Muhammed stands next to his stack of ENGL heads. On the bottom row is his ENGL Savage 120. Muhammed also used a Savage 120 live at a show on Summer Slaughter 2009.

You can see an ENGL e670 Special Edition behind Muhammed. It's clearly an e670 because of the distinct blacked-out appearance, 2 rows of channel controls, and the unique button-features on the right side of the amp face.

"to get the low A string to sound clear, we will use ENGL Savage 120s on the new album, as well as ENGL XXL cabs and a trick or 2 in addition...i have always been very creative when it comes to studio sessions, so we might come up with last minute ideas as well."

In this Q&A Muhammed is talking about what he used to record the third Necrophagist album, which remains unreleased to this day.
