i currently run an acoustic b200h into a g-k goldline 410 cab (400 watts at 4 oms). looking back, the only reason i really got it was because of money (or lack thereof), and the backline 600 head i tried sounded like crap. so now im considering buying a new, better head around the $400/$500 range, new OR used. something with a little more power (but still under 400w), and plenty of eq adjustment. something with 2 speaker outputs would be a plus, in case i decide to mix things up and get 2 8-ohm cabs later down the road. heres what im looking at, and why i am considering them. any other suggestions are welcome as well: ampeg b2r- ampeg heads generally have pretty good reviews from what ive seen, and the 9-band eq looks attractive markbass little mark 250- ive loved the tone of every markbass amp ive ever played through, be it a combo or stack, and at that price... tech 21 landmark 300- i played through one once a while ago, and the 2-channel switching comes in handy. ive used sansamps numerous times for various styles, and it uses the same tube emulation circuitry that sansamps use eden wtx-260- i giged through one of these playing for my church once, and the tone it spat out impressed me nemesis na-320- never used one of these before, but ive read some good stuff about them. the parametric eq has a full sweep rather than just a mid sweep, so i can experiment a little more if anyone has any expirience with any of these heads, or a reason to get/not get one, let me know! thanks!
