I really need a new amp. I've been playing my 20-watt practice amp w/ my guitarists who have line 6 150 watts and 75 watts. Ive been able to catch up in practice, but there usually on 2-4 volume and im set to around 7-9 volume. So, wats the best combo/ Half stack under $ 500? i play metal, btw. i was thinking this: http://bass-guitars.musiciansfriend.com/product/Kustom-Groove-310C-Bass-Combo-Amp?sku=480765, but im concerned its not quite portable enough, (not for practice, of course not, but for bringing it anywhere) Ive considered the Ampeg BA210SP, but ppl here seem to not rly enjoy it, and ive also considered the Ampeg BA115HPT, but i like some goodies in my amps. (im 12, i need the goddies i can get in one package. Ive considered Line 6, like the HD150 or 175. how are those? Could they compete w/ my gui****s' amps? Im looking for around 200 watts, give or take. Ive also considered of course the option the building a half stack through the used market, and most of these im gunning for are b-stock. XLR out is a plus, but i can live without one. Thankyou for all your help Talkbass, the fountain of useful and useless knowledge.
