Hello friendly bass players! I need your council of experts. I want to buy a preampli that I intend to use with a poweramp QSC RMX 1450 and my enclosure Ampeg SVT-210HE of which I think soon of adding an enclosure Ampeg SVT-15E to be able to benefit from the biamplification. In this moment I hesitate between two possiblities: one proposes new Ampeg SVP-PRO to 420 $ and also Demeter to me VTBP-201s which was used as a demo unit in a store of bass for 550 $. For Ampeg the salesman said to me that it could always have to me it at this price whereas Demeter is likely to leave quickly. Which from these two preamp is a better business to be seized? Is the quality of the sound of Demeter really better than the quality of Ampeg? Do you think that the preamp Demeter will sound well with my Ampeg enclosures? I want to use it to play especially of the funk and the reggae. Thank you in advance for your answers.
