The Vermin shape combines classic and modern aspects of bass guitar designs you could easily play both in your prog and your slam death band. It's a comfortable and rather lightweight shape with two cutaways, the upper one being long enough to provide good balance and the lower one leaving lots of space for perfect access to the highest frets.


The Reaper might be Stefan Schäfers most unique take on instruments for heavy extreme music. Based on a traditional two-cutaway design Stefan managed to make the Reaper unmistakably original wth a few tweaks. The shape provides guaranteed balance event with huge scales and string numbers while the look seems to perfectly fit lowest tunings, as every chord and every open B string will sound extra evil coming from this monster shape!


Ever since 666strings started building instruments we have listened closely to our customers. From tiny little tweaks to our own design to full on custom shapes there is not a single wish we have not fulfilled in all those years and the instruments that were spawned in those processes are nothing short of stunning!
