Product Description
A new transformerless input stage forms a clean and transparent front-end, together with the two selectable output stages you can get the low mid punch and thick sound associated with British Class A from the early 70’s as well as a more modern clean tone from the 80’s and 90’s. SP502 is also equipped with a saturation stage that can be selected to add some extra harmonics to the signal. The sweepable HPF from 30Hz to 400Hz allows precision crafting of the low end. A new function is that the instrument input can be routed directly to the output stage without passing the preamp stage (the saturation circuit and HPF can still be inserted). The DI direct mode together with the vintage Class A stage gives you a very nice discrete sound path for bass recording.
