Hey Talkbass, first post here. Anyway, Ive finally gotten the opportunity to upgrade from my little combo amp. I use a Peavey Cirrus BXP 4 string bass at the moment, and play metal. Im trying for grindy, crispy, growly, but at the same time clean tone. Clean, but not sterile. In the future I plan on getting a 5er, so I need something that can handle a low B or a low A easily. Portability isnt an issue. Im looking at 2 options at the moment. GK 700RB or a 1001RB head with a 410 Neo cab or Markbass Little Mark Tube 800 with a standard Markbass 410 cab Ive tried both in store but the batteries in the bass started dying in the middle of trying the Markbass, so I never really got a good comparison. I understand that these 2 amps arent exactly in the same league but my options are limited. There are more GK, Markbass, and SWR heads and cabs in the store but Ive pretty much narrowed it down the RB and the Tube 800. What do you think? Also Theres a store out of town that has a few Ampegs. I havent checked them out yet, but if someone believes that an Ampeg product can satisfy my needs then I will. Please, make any recommendations you can. Thanks.
