Howdy. I will soon be playing for a band that will require me to get a rather sizable rig to even be heard. They play somewhat progressive death metal, Two guitarists will fullstacks(peavey5150 and mesaboogie triple rect IIRC), and a drummer whome I've played with in the past who plays the drums like he's muay thai fighter and now he's mic'ed and triggered so its volume++ from there. And I wont be using a PA for rehearsals. My budget is south of $1500 so I'm looking at the GK1001rb-ii, avatar cabs and carvin b1500 and rbx10.4's. I'm leaning towards the b1500(currently 650 bucks on carvin.com), so only about 50 or more bills then what rmc sells the 1001rbii for, and the carvin does 1250watts(4ohms) vs 700(4ohms). but I haven't used either of these heads in person. Is there anything I should be aware of when deciding between these two heads? Especially regarding reliability/durability if there are any concerns between the two. Also leaning towards avatar cabs,(esp if I do get the GK).. their 410's while having a lot of praise here on TB also go for $100 less then the carvin's. Is there any note worthy difference between them? Also, I'm not sure how much speaker I'll comfortably need for this rig. Are my assumptions correct in needing a little more then just a 410 cab? w/ the avatar I'm thinking about pairing it up with a 112 or 212, not sure if what I'd honestly need. BTW to get out the way -My EQ settings are typically flat, slight mid boost and I play a grunty warwick corvette6.. granted it has bassline pickups and it is a fretless w/flatwounds.. -Telling them to turn the volume down argument, while extremely valid and will come into play.. From past experience I know I sometimes Just dont care to deal with it. If you guys think guitars are bad, My drummer friend would make your brain go pop.(that said, he's an absolutely BLAST to play with so I put up with it). Thanks.
