In the youtube movie its twice Bag End S15-D
Or I can buy the head seperetly and buy a secondhand
Bag End Q10BX-D.
What would be the best combination?

I play a Schecter stiletto studio 5 tuned one step lower.
thickest string is an A
I play most of the time Metal, Rock, jamiroquai
My favorite bass player is Fieldy of korn.
Some of my Favorite bands:
Amon Amarth, Fintroll, Arch enemy, Dark Tranquillity, Children of Bodom, Coal Chamber,
Deth klok, Mnemic, Decapitaded, Tyr, Death Angel,

I hope you guys can advise me.

Greetings Dave.
