The phono outs on the SP-303 are quite vulnerable, be careful not to walk in to your wires while itās plugged in, or yank it otherwise. They might get damaged.
I owned the SP-303 and also later the SP-606. I wanted to get another SP recently but I went for the Zoom Sampletrak ST-224, which for all intents and purposes could have been part of the SP line. Itās set up the same way. But it has time stretch and chromatic playing of samples. Bit rates 32, 16, 8 which eight is awesome, especialy being able to tune it down for that real grit. Recommended.
