First off... My current setup is an Ibanez GSR205 bass with a Peavey Tour TKO 115 combo amp.
I play for a metalcore band and my tuning is:
I play a progressive kind of style and use a lot of low end.
Amp wise: I want something punchy and clean that can handle extreme low end (I.E... drop G#) without distorting.
Lets just say price doesn't matter at this point.
(they're maybe a few other things I may have forgot)
Things I've been looking at:
Amp heads: Gallien Krueger 700rb (not much else really)
Gallien Krueger Neo 212 and 410,
Harke Hydrive 410 and 115,
Trace Elliot 1818 and 1048H,
Ashdown MAG 414T Deep,
Avatar 212 (haven't heard it for myself really but I've heard really good reviews on them).
Orange OBC 410,
Fender Rumble 115, 212, and 410.
^ Quite a wide range there. xD
For basses, I'm not too sure what I am exactly looking for, it's usually something you find out once you actually pick up a bass (could apply with amps really).
Things I've been looking at: Musicman, Warwick, Jackson, maybe an Ibanez.
I know there's a lot of things I may have missed out, but I hope someone on here can help me decide for a possible amp (and bass) for the future.
