Roland SDX-330

The record treats the Roland SDX-330 badly. No service manual, no full review and no confirmed spec sheet have turned up in the usual archives. What survives comes almost entirely from mid-1990s British music-press pages, where the SDX-330 shows up alongside two similarly named siblings.

Sound on Sound (April 1995, p.75) grouped the SDX-330 with the SDE-330 and SRV-330 in an advertisement for Roland's new-generation samplers and effects units. That suggests a coordinated family of rack processors, though the ad copy doesn't say what each unit actually did. A June 1996 Sound on Sound effects-unit price survey (p.53) listed the SDX-330 at £799, with the SDE-330 and SRV-330 at £856, and below Roland's RSS-10 3D processor at £2,199. The following month, a Music Connections dealer ad in the same magazine (July 1996, p.63) showed the SDX-330 at a much lower £450 - likely a discounted direct-sale price.

That is the extent of it. The SDX-330 was a Roland effects unit of the mid-1990s, sold in the UK for roughly £450-£799, and it has slipped through the documentation almost completely.
