With an assist from ADL's Anthony DeMaria, PreSonus stepped into high end studio territory with the ADL 600 and the results are nothing short of stellar. This dual channel, high-voltage tube preamp serves up a huge tone that's clear as a bell and reminiscent of classic vintage gear. This old-world sound is complimented with a modern feature set, featuring a switchable and tunable high-pass, switchable impedance, and separate coarse and fine gain control to dial in the precise amount of drive you're looking for. When you're done tracking, flip the ADL 600 over to line operation to give your whole mix a thermionic kiss and take your productions to the next level.
