This preamp captures the very British sound of the 60�??s; it was new, innovative, bright and alive! It seemed so foreign at first but became an integral part of the scene that was to come. If you are looking for that very rich style and sound the SOLARIS AX7S is waiting for you. It offers a lively boost of distortion rich in overtones and very flexible non-rigid harmonics. Comes loaded with sustain that will assist you in getting that sound you have been looking for. Plug-in, take a test drive in this sporty model now! It comes fully equipped for plug-n-play with a vintage NOS 12AX7 triode.
