Here’s a serviced, tested, and fully loaded Eventide H3500 Sampling Ultra-Harmonizer. This classic multi effects box has the gray and white DFX front panel and coloring, but we have updated it with the mammoth "Kitchen Sink/Plus+" H3500-DFX upgrade kit, which contains all the original D/SE presets and the H3500-DFX presets, giving you nearly every preset and algorithm ever created for the H3000/H3500 series. This is the mother of all H3000 upgrades, with 22 algorithms and 755 presets, including all the Stevie Vai and Mod Factory presets, and the 3D spatial imaging effects.  It has all the presets and programs found in the H3000 SE, and more. This classic H3000, found in every major sound studio, contains a wide variety of high quality sounds and effects including layered pitch shift, dual pitch shift, stereo shift, reverse pitch shift, swept comb filter, swept reverb, reverb factory, ultra-tap, long digiplex, dual digiplex, long digiplex, patch factory, stutter, vocoder, multi-shift, band delay, string modeler, phaser, diatonic shift, etc.  The unit has 2 balanced inputs and 2 balanced outs, plus 3 MIDI ports. A switch on the rear panel selects between 115 and 230 volts. A power cord is included.  (Users outside North America please note: with 50 Hz. power, some acoustic hum will be heard from inside the unit. This is normal with all H3000's.) The unit will be well packed and is guaranteed to work properly on arrival.The sampler board in this unit allows 95 seconds of mono sampling or 47.5 seconds of stereo sampling.Our shop received this unit in good working order but for preventative maintenance we replaced all the electrolytic capacitors in the power supply, serviced the main Molex connector, replaced the battery-backup NV-RAM IC, and did a complete calibration & check out.
The unit has 2 balanced inputs and 2 balanced outs, plus 3 MIDI ports. A switch on the rear panel selects between 115 and 230 volts. A copy of the manual and a power cord are included.  The unit will be well packed and is guaranteed to work properly on arrival.Cosmetics are very good. The only flaws are some worn areas in the paint around the edges of the front panel, which have been touched up with a paint pen. Mechanically it is in very good condition and the electronics are clean and tight.Please note: we came up with the "Kitchen Sink PLUS" nickname for these fully loaded units, but we've noticed that other sellers have been listing units with smaller program sets under the same name. If you are looking at a "Kitchen Sink" units to that from another seller, we suggest that you make sure that it has all 22 algorithms and 754 presets, as our units do.Here's a complete list of the presets:Algorithms:100-123
100 - Diatonic Shift, a pitch shifter that stays in key
101 - Layered Shift, two pitch shifts from one input
102 - Dual Shift, two separate pitch shifters
103 - Stereo Shift, Mono-compatible stereo pitch shifting(maintains stereo imaging)
104 - Reverse Shift, backwards-talking pitch shift
105 - Swept Combs, six sweepable delay lines, with stereo panning
106 - Swept Reverb, a dense reverb with smooth sweep capability
107 - Reverb Factory, A full-featured reverb with EQ and flexible gating
108 - Ultra-Tap, twelve delay taps with full control over panning, level and delay. includes a diffuser to generate dense gate reverb effects.
109 - Long Digiplex, a 1.5 second delay with smooth delay control
110 - Dual Digiplex, a stereo delay with smooth delay change
111 - Patch Factory, a "modular" effects program which let you design your own effect. "Patch" together delay lines, filters and pitch shifting to create never-heard-before effects
112 - Stutter, get that st.st.stutter sound-effortlessly
114 - Dense Room, our densest reverb, with unique front/back position control
115 - Vocoder, this is Eventide’s version of the classic vocoding effect
116 - Multi-Shift, two six-octave pitch shifters, two delays, panning and patchable feedback paths make this program incredibly useful
117 - Band Delay, a multi-tap delay line feeding eight resonant bandpass filters make for some sounds
118 - String Modeler, this program let H3000 double as an extra voice in your midi rack
119 - Phaser, a wonderfully thick, smooth, phase-shifting effect that is hard to beat
122 - mod factory one of the latest algorithms, adds effects such as delay ducking, BPM delays and sweeps, compression, manual flanging, smooth autopanning, audio triggered sweeps and much more
123 - mod factory two
 Presets:
150. 12BYRD-STRING. MULTI-SHIFT. Nice,12-stringy program. Uses lower octave doubling. Watch clipping. 200. ALIENS. REVERSE SHIFT. Transforms voice into a rough, alien-like sound.
201. AMBIENCE. ULTRA-TAP. Use this to add ambience without muddying the mix.
202. A MINOR CHORDS. DIATONIC SHIFT. Play or sing a solo line in A minor. The H3000 will generate two perfect 'in-key' harmonies.
203. ANTI-AMBIENCE. REVERSE SHIFT. This is a reverb-like sound created from REVERSE SHIFT. Sounds great on guitar. Mr. Cooder's favorite.
204. AVANT-GARDE. REVERSE SHIFT. A REVERSE SHIFT effect that generates descending, chromatic lines.
205. BASS SHIFT. LAYERED SHIFT. A doubling effect intended for bass guitar. One channel is shifted up an octave. The other is slightly detuned.
206. BIG SNARE. REVERB FACTORY. Thickens up weak, drum sounds. Try increasing gate time to get a more 'gated' effect.
207. BIG SWEEP. SWEPT REVERB. To really hear the sweep, turn up the master feedback, make some noise, and then change the master delay.
208. BIZARRMONIZER. LAYERED SHIFT. Generates a bizarre, upward sweeping pitch shift.
209. BRIGHT ROOM. REVERB FACTORY. A short, bright reverb.
210. CANNONS. REVERSE SHIFT. A unique, sweeping sound that's great on drums. Try playing a tom solo through this.
211. CANYON. REVERB FACTORY. Our biggest reverb sound, like an echoing canyon.
212. CIRCLES. ULTRA-TAP. A stereo-delay effect that seems to circle around your head. The effect is most noticeable on short sounds, like handclaps.
213. DARK ROOM. REVERB FACTORY. A very mellow, room sound.
214. DEATH FLANGE. SWEPT REVERB. A deep, intense flange that's great for thickening up a synthesized bass line.
