Greetings TB~

I was trying sift through the AK mega thread and started to melt my brain...so I figured I try out starting a new thread(my first!). I am looking to buy a AK 1203 or 1533(I don't want to go any heavier than 37lbs) and would like to here what you all would get and why. I mainly play world and R&B style and starting to learn to slap..pretty much always clean. I am looking to get a nice full rich sound that handles the low B string and can get through the mix...no muddiness. I was thinking that the 1203 could be used for most gigs, but if I needed more power I can pair it with the GK Neo112 (has anybody tried this combo?) or I can step up and get the 1533 which would cover all my loudness needs by itself but its 11lbs heavier. For those that have had experience with both: what are the main differences sonically between the 1203 and the 1533? Can they both handle the low b equally as well. which one sounds better to you? and last question, has any one a/b or had experience with the Thunderchild 12 and 15? how do these compare to the Hathors(especially with the low B string)

Thanks!
