Check the listing for details. Roland SP-404SX | Sampler and Effect Pedal - Great Condition. Condition: Used. Listed at 399.00 USD. Roland SP-404SX | Sampler and Effect Pedal - Great Condition. Product Description: Powerful, on-the-go sampler! The SP-404SX puts you in touch with unbelievable sound quality in a compact format. The fun really begins with the enhanced pattern sequencer, complete with quantize mode for in-the-pocket grooving. The SP-404SX has 29 built-in DSP effects, so you can get creative with filter, delay, and more. Don't worry about running out of space — you get a 1GB SD card for 90 minutes of stereo sampling time. And with support for up to 32GB SD cards, you can sample up to 48 hours (stereo!) with your Roland SP-404SX. Seller's Note: The legacy speaks for itself on this one but I personally would like to add that the compressor on this thing is super fun to run busses through for that flattened/vintage sampler sound!
