Description
The H9 Harmonizer Gen 2 brings Eventide's iconic multi-effects pedal into a new era delivering studio-quality sound and creative flexibility in a compact, performance-ready format.
Building on everything players loved about H9 Classics (H9 Max, H9 Core, H9 Standard), H9 Harmonizer expands the platform with the full H90 algorithm lineup, modern ARM processing, and a faster, more intuitive workflow for today's stage and studio rigs.
Designed to Grow
The H9 Harmonizer is built as a long-term platform. It includes the complete H9 Max library and remains fully compatible with legacy presets. No subscriptions or hidden unlocks. New algorithms will continue to roll out as updates.
Integrated with Eventide Control and powered by a modern software foundation, The H9 Harmonizer is designed to evolve alongside the needs of today's players.
Signature Sound
H9 Gen 2 combines the full legacy of the original H9 with the expanded creative range of the H90. It includes the full 74-algorithm lineup found in the H90, including all 52 original H9 Max algorithms, spanning delay, reverb, pitch, granular, vocal FX, looping, and much more. For longtime H9 users, it's everything you love, now expanded. For new players, it's the most direct path into Eventide's flagship effects platform.
Built on the same modern ARM processing as the H90 and H9000, H9 delivers higher-fidelity sound, improved overall performance, and true spillover on preset changes for seamless transitions. Proprietary Spectral Instantaneous Frequency Tracking (SIFT) tech produces pristine polyphonic pitch shifting and powers algorithms such as Polysynth, Polyphony, Polyflex, and Prism Shift.
Built to Play
H9 Harmonizer is designed to make great sounds easier to access. A larger 2.5" display, updated controls, and a simplified interface make navigation faster and more intuitive than the original H9, while preserving the immediacy players expect from a compact pedal format.
Its workflow is built around three core modes: Select Mode, Bank Mode, and Perform Mode. Together, they create a faster, more performance-ready experience for browsing presets, organizing sounds for live use, and controlling effects in real time. With HotSwitch and HotKnob macro control, plus flexible footswitch behavior, H9 feels less like a menu-driven processor and more like an actual instrument.
Made for Modern Rigs
H9 supports one algorithm at a time, featuring flexible I/O and global or preset-specific settings. The various routing options make it easy to slot into pedalboards, amp loops, hybrid rigs, and studio setups.
Get connected quickly and easily with Bluetooth support for H90 Control, 5-pin MIDI I/O, stereo audio I/O, as well as expression and aux control. The next generation of H9 is ready for the demands of stage and studio. It's compact enough to simplify a board, yet connected enough to anchor a modern rig.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
