The Rootmaster 800 EVO III is a precision-engineered bass amplifier with a comprehensive EQ system, Ashdown Sub Harmonic Generator, Compression control, and a versatile Valve Emulated drive. It's the Swiss army knife for bass players, excelling in any musical setting, whether on stage or in the studio. In a world that is increasingly embracing silent stages and in-ear monitoring, Ashdown remains resolute in its commitment to delivering top-tier bass amplifiers. The Rootmaster EVO III, in response to the evolving needs of bass players, now features a new Analog Cab Sim Di output. This innovation provides you with a newfound level of flexibility in managing your on-stage and front-of-house monitoring, empowering you to achieve an exceptional monitor mix effortlessly.
As for raw power, the Rootmaster EVO III boasts a staggering 800 Watts of output, making it well-suited for a wide range of performance scenarios. It is versatile in terms of power requirements, accommodating both 115-230 Volts, making it a globetrotter's dream. The two Neutrik Speakon/Jack outputs ensure robust and reliable connectivity, and the frequency response spans from -3dB at 17Hz to 30KHz, capturing the entire bass spectrum with unparalleled precision. The high and low instrument inputs, along with the line input, provide flexibility for different basses and sources.
A balanced D.I. output guarantees that your signal is primed for front-of-house mixing, and a tuner output simplifies your tuning setup. The rear panel of the amp hosts a balanced D.I. with an XLR socket, delivering a post-E.Q. and post-effects signal. You can easily select this option using the Balanced default setting on the front of the amp. But the innovation doesn't stop there; Ashdown has meticulously designed a series of filters, finely tuned to replicate the response of their legendary ABM
cabinets.
You can choose between engaging the CAB SIM DI or the BALANCED DI output through the XLR DI option, enabling you to tailor your sound to perfection. Additionally, you have the choice between PORTED and SEALED enclosure options, affecting the resonance and bottom end response of your sound. The SPEAKER option presents a choice between a 10" speaker, known for its tight, defined mid-range, and a 15" speaker, prized for its depth and clarity.
Finally, the HORN option allows you to add a high-end boost at around 5k, emulating the presence of a horn within a cabinet. The possibilities are endless, offering a level of customization that is unparalleled.

Q & A

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.
