Hi guys, I'm writing because i'm having some doubts about my gear. I am currently playing through a Line6 lowdown hd400 head with a GK MBE212 cab. It's been 2 years since i bought it and i had never had any complains about the head. However, lately i'm not liking the sound i'm getting. I don't really know why because i have always loved that head. But lately i feel like something is missing in my sound. So i've been thinking about buying another head. I've been reading and listening to the tc electronic bh500 lately but i don't really know if that's upgrading or just changing a little bit. I also like the orange bass terror or the ashdown abm500 but i cannot afford these two yet. What do you think? Should i wait and keep on playing with my line6 until i can afford something better or go for tc?
