"In the effects loop this year I have…the Boss SE70 Modeling Effects unit that I'm using it for a flange. We use this multi purpose. I t has ring mods, slap-back echos, just anything utility type thing," says Billy Gibbons's guitar tech about the Boss SE-70 Super Effects Processor.

"I love my Boss SE70s. (...) You can get awesome distortion sounds from the SE70. (...) I've got four SE70s, and I programme the hell out of them. I've really gone mad with them." - Liam Howlett interviewed by Sound To Sound

The SE-70 is a half rack size digital multi effect processor. It has some multi-effects setups for guitar/bass/keyboard/vocal, though they're processed in 32kHz mode. Available effects: Reverb, Gate Reverb, Ambience, Delay, Chorus, Pitch Shift, Phaser, Flanger, Ring Modulator, Noise Suppressor, Overdrive/Distortion, Rotary, Enhancer, Panning/Tremolo, Slow Gear, Compressor/Limiter, Auto Wah, Guitar Amp Simulator, Vibrato, Feedbacker, Bass Amp Simulator, De-esser, Equalizer, Vocoder, Guitar Synth, Bass Synth, Mixer, Hum Canceler, Vocal Canceler, Key Changer, 2 Second Digital Sampler, plus a Chromatic Tuner and Metronome.

Bass multi includes: Slow gear, comp/limit, auto wah, overdrive/distortion, eq, enhancer, bass amp simulator, noise suppressor, pitch shifter, vibrato, phaser, flanger, delay, chorus, panning/tremolo.

Single algorithms include interesting ones like: 21 band vocoder 12 voice pitch shifter 16 unit chorus, etc. Signal level is 0dB or -20dB in.

If you turn the reverb on heavily, with some wrong values, you get exciting distortion effects, which are one of the Prodigy's trademarks (at least on the FOTL-album, you can hear them on SMBU and Narayan, for example) Used:

Liam once said to an interviewer, asking him what advice he'd give to upcoming musicians: "I'd like to quote Keith here, who said 'You can never have enough SE-70's'... "

On Guitar Geek, this rig diagram shows that Aldrich uses a Boss SE-70.

Mentioned by Merzbow in a 2025 interview with Roland:

The BOSS SE-70 digital effects processor, on the other hand, was all over my work in the late ’90s. It had 35 different effects, each with its own EQ settings, so that I could push the distortion to extremes; it was really useful!

Scott's website lists the SE-70 multi effects processor on the gear page.

"Our sound sources include quite a lot of original analog gear (OSCAR, Korg Poly-6, EMS synthi, Roland Juno60 - all midi-retro fitted BTW) plus the usual samplers (Emax, s1000, Samplecell II). These are controlled by sequencers including Studio Vision, Cubase and the "retro-style" Doepfer (originally made for Kraftwerk). The sounds are intially effected by various standard echoes and FX including a Roland SDX-330 Dimensional Expander (3D-ish) and a Boss SE70 (good vocoder presets!)."

According to a GuitarGeek rig diagram, Walter Becker of Steely Dan used two Boss SE-70 Super Effects Processors.

Ronald's expansive rack setup included at least two Boss SE-70's as seen on the top row in this picture. Used for distortions, pitch shifters, delays and reverbs.

"When we recorded with David Newfeld, he swore by the Boss SE-70 multi-FX unit, and I ended up buying one myself afterwards. It’s great for combining a ton of effects, and is always useful for adding more random elements to sounds."

Spectrasonics Studio List The equipment list for the Spectrasonics studio reads like a gear-head's dream. Favourites amongst Eric's sizeable synthesizer collection include the Access Virus, the Prophet VS, his collection of Waldorf synthesizers, and a 1976 Yamaha CS80. "It's my favourite axe to play, because of the awesome polyphonic aftertouch and that sensuous ribbon," explains Eric.

For effects processing Eric is a fan of the Roland SRV330 reverb, an item that "gets missed by most people, mainly because it doesn't say Lexicon on the front panel." For distortion tricks Eric often uses a rare Boss GL100 guitar preamp: "It's basically the history of Boss pedals in one rack space."

Mixing, until recently, was done on some "very odd, custom-made analogue mixers made by a guy named Mo West," reveals Eric. He recently purchased a Roland VM 7000-series mixer, however, taking him one step closer to an all-digital setup.
