With a Rupert Neve-designed transformer and a class-A biased discrete FET amplifier, the RNDI elegantly balances any instrument signal - whether straight from a bass guitar or from a screaming 100w amp.

RNDI's unique response delivers a powerful and vibrant direct sound capable of reproducing the full harmonic depth of basses, guitars, acoustic instruments, and professional line level sources. With portable, powerful, larger-than-life tone for your instrument and amplifier signals, the RNDI is truly the first standalone DI worthy of the Rupert Neve name.


• Groundbreaking Direct Tone - where class-A, discrete amplifiers meet Rupert's custom transformers.

• Huge Headroom - the high input headroom of +21.5dBU is capable of handling professional, line level sources without a pad and in speaker mode, the RNDI can handle the full output of a 1000-watt power amplifier (92 Vrms or 266Vp-p).

• Rugged Solid-Steel chassis features an industrial-grade powder coating, and is built to withstand the severe stresses of life on the road.

• Takes All Kinds - the RNDI has immensely consistent performance across a wide variety of sources due to its 2M Ohm discrete FET input and high headroom. In instrument mode, you can even connect a professional line level interface output to "Re-Preamp" a previously recorded source.

• Drive Longer Lines - the low impedance transformer coupled output below 50 ohms is capable of driving long lines with unrivaled high frequency performance.

• 1/4" THRU Output - In instrument mode the THRU output can feed the amplifier input for reinforcement. In speaker mode, the THRU is used to feed the amplified signal to the speaker.

• Best in Class Phase Coherence - excellent at all frequencies, which keeps the sound well-balanced and natural, and is especially vital when blending the direct signal with a microphone capture of the same source.

• Ground Lift switch on the back helps fix any problematic grounding.

• Phantom Powered.

Fantastic sounding product. If you are using amp simulations, this is an amazing front end for your DAW that gives the guitar the perfect character. The high end is smooth as butter and the low end is thick and gooey. Amazing on bass as well. It is expensive, but great tone comes at a price. I have a Radial JDI, Avalon U5 and a Countryman 85. The Rupert Neve RNDI sits above them all.

Great sounding DI for acoustic guitar and bass 3 of 3 customers found this review helpful

Rupert Neve is a legend in the audio industry, famous for his analogue mixing consoles and outboard studio gear. I have been using the Neve RNDI for the past year on acoustic guitars and MTD 535 bass for live and recording sessions. Compared to the Radial Pro DI, the Neve RNDI has warmth, a very pleasing crisp top end and a punchy bottom end. Almost tube-like without the worries of a tube. The RNDI has a built-in switch where you have the option of connecting it directly from your amp speaker output without blowing the unit. Never used it but nice to know it's available. If you are in the market for other options, there is the Noble or REDDI DI but they are a lot more expensive and not available locally. Overall, the Neve DI is great sounding and reasonable price.

I bought this on sale and was blown away. I read the reviews and wondered how you could get that excited over a DI. I run my sansamp BDDI into it and get the best bass sound I've ever recorded. Great unit you'll always keep. Sounds awesome on my Martin acoustic as well.

Performance Warranty Banner

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: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
  • USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 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.
