okay so i have a Tascam US-144 MKII, an SM58, and an SM7b. i use a Dell from the 1800s. I use Mixcraft as my DAW, FL Studio 9 to arrange and sequence drums sampled from ezdrummer dfh. I use Amplitube 3 for amp modeling. lemme know if i may have left something out. anyway. i need to know what my next buy should be. its obviously just going to be a modest setup until i get my promotion. then im going all out. So short term suggestions and perhaps long term? Thanks.
