Product SKU: 456HD-M

The Roger Mayer 456HD-M Stereo is designed to reproduce the desirable characteristics of recording to tape in the digital age with zero latency, no extra CPU load and a discrete Class A analogue signal path. Building on the success of the smaller 456HD processors, the 456HD-M Stereo is a mastering-grade stereo 19" 2U rack unit designed for larger studio set-ups.

Applications include primary tracking, mix busses, mixing and mastering.

The 456HD Analogue Wave Shaping Process is an innovative way to experience modern dynamic and harmonic control in real time with zero latency. It was inspired by the desirable qualities of a tape recording and can reproduce their dynamic compression and harmonic properties accurately to correct and enhance pre and post digital recordings.

The 456HD-M is an evolution from the experience and needs of industry producers and engineers from the many and varied uses for audio in production.

The 456 extended low and high frequency response exceeds that of an original vintage tape recorder operating at 15ips or 30ips all without any tape hiss producing what is in effect HD TAPE RECORDING. The problems of tape recorder setup and cost of multi-track tape can be eliminated as you now have access to all of the desirable analogue properties of the vintage ways but with added high speed dynamics processing.

No hassle returns

We know how much of a gamble it can be purchasing a guitar online without trying it first. That’s why if you receive your order and it’s not as you expected, let us know within 14 working days and we will have it collected by UPS.

Once back we will refund (minus restocking charge) or exchange the item if preferred. Online purchases only.

Fully setup & triple checked quality control

We have in-house guitar technicians here at Guitar Village, so that means all guitars in stock are constantly checked and maintained for optimum playability.

As soon as a guitar is sold it will be fully set-up to ensure it is playing great right out of the box. It will then go through an inspection checklist and is checked again for quality and playability by two more members of staff. Let us know any preferred setup requirements and we will be happy to oblige!


All new products come with a 12 month warranty as standard. Some products will come with an extended manufacturer’s warranty - these will be included with the product and will usually need to be activated after purchase via the manufacturer’s website. Ex Demo products will also come with a 12 month warranty. Pre-owned products come with a 3 month warranty.

Real time stock levels

Fed up with websites advertising guitar that they don’t actually have? So are we! The Guitar Village website is updated in real-time, so that means the second we sell out of a guitar the website will say ‘out of stock’. If it says ‘In Stock’, rest assured we do actually have it in stock and ready to go!

Actual image photography

We don’t want you to have any nasty surprises when you receive a guitar from us so we do our own photography in-house.

Any high-end guitar with a figured finish or unique features will have its own images. If you see “✓ Actual product in photograph(s)” next to the product listing, this will be the actual item you receive.

Any guitar priced under £2000 with an opaque/block finish, or lightly figured woods may have an example image of the guitar.

Click & collect

Don’t fancy the painful wait at home for the courier to deliver your new toy?

If you’re not a million miles away not come in and collect it from the shop? All you need to do it select “Collect from store” at the checkout, pay in full online then pop in with proof of purchase, along with some photo ID* and you can take it away right then and there!

*Photo ID must be a valid passport or driving license.

Ex Demo/New Old Stock Products

Occasionally we list items as ‘Ex Demo’ or ‘New Old Stock’. These are new but may not necessarily be in perfect condition and could have had minor repairs, marks, scratches and/or other defects.

These will be fully described and discounted accordingly.

At Guitar Village we're committed to offering you the very best shopping experience possible. We strive to provide you with an unmatched choice of guitars as well as our award-winning friendly customer service, combined with the best prices in the UK. Occasionally the odd price pops up a little cheaper somewhere else. We don't want any of our customers to ever have to decide between our high level of service and a lower price, so we will always endeavour to price match our UK competitors.

To qualify for a price match it must be:

  • From an official authorised dealer,
  • Identical to the product we are selling (model, colour, specs),
  • In stock and ready to ship,
  • Clearly advertised at the cheaper price on their website (not a price quoted over the phone),
  • An outright purchase price, not including finance, part exchange or any other offer.

Usually these cheaper prices are offered by online-only warehouse retailers with little overheads and a "stack 'em high, sell 'em cheap" philosophy, sacrificing the customer service that's essential to back-up any purchase.

When you buy from Guitar Village you can rest assured that your item will be:

  • In stock if the website says it is,
  • Guitars fully setup to any given requirements by one of our full time in-house guitar techs prior to dispatch,
  • Triple checked through our extensive quality control,
  • Safely and securely packaged, then dispatched using UPS - fully tracked and insured,
  • Full after-sales customer support.
