The SDE-330 is a programmable digital delay system with  RSS 3D processing to create 3D sound fields. It has extensive remote controllability with most parameters controllable over Midi. It has stereo inputs & outputs with twin effect engines for true-stereo operation

RSS (Roland Sound Space) is a Roland research project

Controllers and range scaling can be defined so a mod wheel (for example) can control 100% of the value or 10%. Five of these mappings are available

It’s a twin-engine delay line with resonant multimode filters, modulation matrix, feedback & LFO

“Woo boy I like it a lot. Super easy to program, and it sounds gorgeous. It’s a nice glossy rub over everything”

“Best digital delay I’ve ever used, easy to program etc”

“The 3D is subtle, but the 3D non-linear reverbs are insane crazy”

“SDE-330 is one of the most versatile delays of today… not just a great effector – its an expressive musical instrument”

Owners Manual

In excellent condition with minimal rack rash. Tested & working 100%. 100 Volt Japanese-spec model, will require a transformer for use in the UK / EU – see the Technical tab for details. Photos show the SDE-330 for sale

Stereo-in, stereo-out digital effects unit with lots of user memories. Inputs & outputs are on jack sockets and levels are switchable +4 / -10 dB to match pro or semi-pro equipment

You can use a cheap 110 Volt eBay / Amazon adaptor to power this unit. However I would recommend using a better-quality unit such as the Airlink product. The device is rated at 100 Volts. Use of a 110 Volt supply (typical American adaptors are 110 Volt) is not likely to cause problems as the voltage is within 10% of the rated voltage. However for long-term use a better-quality transformer will run cooler and give better results. The Airlink products are available in 100V and 110V versions - buy appropriately
