Hi, after weeks of having the dilemma of choosing between the Hartke 3500 and the ashdown MAG300 I have finally decided to buy the hartke as it gives me more of a smoother/warmer tone (as my bass sounds has a lot of rattle). anyway the reason Im posting is for two reasons. 1. I would like peoples opinions on cabs and which to go for and even if they make that much difference in sound(?). At the moment I'm thinking the ashdown MAG410T cab as its about the same price of the hartke Im buying. And 2. I've read in a couple of threads about tubes in amps rattling (and hence needing replacement) due to vibrations because the head is placed on top of the cab. So my question is, what can be done to stop this apart from putting the head on the floor? like is there anything i can buy when i have my cab and head? Im thinking towels/sponge or something but Im sure theres a better solution. Thanks for reading!
