I'm looking for a -rackmount- solid state preamp that is Solid State. Before I contact Tech 21, does anybody have any info on this new offering from Tech 21 ? http://www.tech21nyc.com/products/sansamp/vtbassrack.html I'm also curious about the differences between this new one and the RPM. I'm pursuing a deep, clean, warm and round tone for Reggae. Thank You.
