Questions people ask about this model

How do I tell a MKII from an older SP-404?

The MKII has an OLED screen and 'MKII' on the panel. The SP-404, SX and A are older and sell for less.

What should I check on a used Roland SP-404 MKII?

Every pad, every knob, the SD card slot and the USB-C port. Ask whether the SD card is included, and whether the seller's samples will be left on it or wiped.

Is a used Roland SP-404 MKII a good flip?

It sells steadily to beat makers and holds its value. The margin is in units listed without the SD card or with a vague title.

Selling one on

Real synths (Korg, Roland, Moog, Novation, Arturia, Nord) sell very fast. Home arranger keyboards (Yamaha PSR, Casio CT) are slow and low-margin unless free.

Boxable up to 61 keys; 76/88 key units are collection or expensive courier.

Where this price comes from

This is the range the flipper extension uses for a used Roland SP-404 MKII in working order in the UK. It is a starting point, not a quote: condition, extras, the original box and where you are all move the price, and faulty ones sell for much less.

The condition bands above are the same multipliers the extension applies to a listing. On a live Marketplace listing, flipper checks that range against real sold prices and live eBay listings for the exact model, works out your profit after fees and flags faults the seller mentions. It is free while in testing. Join the testers.
