I doubt it. At this point I think it`s all subjective. My Warwick Corvette 5er also sounds great through my Markbass - I mean really great. Good punch, nice round notes, lots of clarity, but it just doesn`t feel like the low end drops as low as I want. Just for comparison sake, the SVT I used literally shook the stage (hell it shook the concrete ground from the show earlier that same day). It felt and sounded huge in the low end and really supported the band (and that was with a 4 string). The MB, on the other hand, just seems to sit in the band instead of supporting it (even with a 5). It`s absolutely great for large jazz ensembles and larger rock bands with keys players, but rock trios? I just think I need a more supportive low end than something that just sits in the band, if that makes any sense.
And believe me when I say that I absolutely adore Markbass. They are phenomenal amps and if I had the chance I`d endorse them (or would they endorse me?) in a second. But since they don`t I have no chance to ask them to make me an amp that does what it does now but with an extended low end, more headroom/power, the ability for more natural overdrive/grit, and a blendable SS and tube preamp I have to look elsewhere. The TSA500 on paper comes close but probably needs more power and I`m not sure if it fixes the low end problem.
As it stands, Markbass amps (to me) are amazing. I can`t speak more highly about them and they`ll forever have me interested in their products and suggesting them to new bassists. But at this point in time I have to look elsewhere for the sound I`m craving, and that`s okay... I don`t think their sales will take THAT big of a hit if I stop buying them
