hi toboe!
i have to be honest, i've never tried out any of those specific pieces before... i'm not sure i can give you good insight as to how they sound or how well they work together. having said that, i think from purely a quality perspective all of those pieces are probably just fine. the question is how good they will sound together.
whenever folks are working with limited budgets, i will usually suggest that they also check out used gear, because in many cases you can pick up even higher quality components for less money because they have suffered some level of depreciation. basses usually hold their value a little bit better than amplifiers from what i've seen.
has anyone else up here had any experience with any of these? feel free to chime in with any feedback!!!
