If you find you want a different brightness setting for stage or studio, unscrew the 4 case back screws, and gently use a miniature screwdriver to adjust the LED BRIGHNESS rotary trimmer. Never use force here!

Silicon Steel is 100% analogue.

The circuit is optimised for operation at 9V. It should work fine at say 12V but there is no real advantage in increasing supply voltage above 9V.

No, please use a 9V DC supply only.

Silicon Steel will always add some warmth (in a good way!) - try setting it for a nice warm clean-ish boost with drive at around 9 o'clock, bass and treble around 1 o'clock and level up to 12 o'clock or higher and adjust from there to taste.

Set Bass and Treble both down to around 8 o'clock, Drive and Level to taste and tweak from there!

Try setting Bass to 5 o'clock (i.e. max), Treble to around 4 o'clock, Drive and Level to taste and tweak from there!

If you find you want a different brightness setting for stage or studio, unscrew the 4 case back screws, and gently use a miniature screwdriver to adjust the LED BRIGHNESS rotary trimmer. Never use force here! Another reason you may want to tweak the led brightness is when changing from or to a higher voltage d.c. supply as this will affect the LED brightness slightly.

This can provide increased headroom which is the amount of input range which the pedal can accept without clipping. You can use external d.c. power supplies up to +18V d.c. This means that for a given input and pad switch setting, you can drive a larger signal without overdriving the input. There may also be a very slight increase in signal to noise ratio. Note that some pedal power modules provide higher voltage isolated outputs e.g. +12V d.c. or higher.

morphtone is 100% analog.

Morphtone will run for around 25 hours on a fresh PP3 battery - this will vary slightly with battery make and your preferred led brightness setting.

Yes, you can use a daisy chain power adaptor or a power brick with non-isolated outputs, as long as connectors are compatible with standard boss-style 9V DC barrel jacks with centre-negative 2.1mm pins. Do not attempt to use an AC power supply.

Potential uses for an EQ pedal are near limitless - here are just a few applications for morphtone : Discover an infinite variety of custom EQ 'meta pedal' combinations. Use morphtone + your favourite overdrive / distortion / fuzz etc. Bass guitar D.I. and pre-amp tone shaping. Change the voice of a guitar sound e.g. make your single coil pickups like humbuckers or vice-versa Drive your tube amp with a custom treble boost / clean boost / mid-focus boost. Troubleshoot frequency problems and tame / notch out unwanted tones. Piezo pickup simulator for electric guitar. A highly tweakable half-cocked fixed wah guitar effect - examples of this include Money For Nothing, many Frank Zappa tracks and of course Mick Ronson's famous guitar tone on Ziggy Stardust.

Graphic EQ's are useful devices but usually have fixed centre frequencies and Q factor per band. This means the audio fine tuning precision of morphtone cannot be matched by most graphic EQ pedals. You would need many more EQ bands than are practical in a typical graphic EQ pedal has to get even close.

No, morphtone works with a 9-18v d.c. pedal power supply or a 9v PP3 battery only.

For guitar, try the middle 0dB pad position and go from there. You may be OK with +10dB for low output pickups or -10dB pad for something with its own high output active preamp - morphtone does not clip readily with most passive instruments.

This is entirely optional as the send and return loops are just like daisy chaining pedals before and/or after Morphtone EQ but the difference is you can switch on your 'meta-pedal' with just the morphtone footswitch if you leave the loop pedal permanently switched on. You can use both loops simultaneously i.e. a pre and a post effect pedal. And of course you can also daisy-chain multiple external pedals in either loop if you want to go even more 'meta'!

This is easy to do - set morph and depth knobs each fully counter-clockwise and then you have a completely flat EQ. The gain can now be set with a combination of the pad switch and the level control. There is plenty of gain available to drive amps etc.

This should get you in the right ball park: morph knob fully clockwise freq range switch to mid width switch to peak freq knob around 10 o'clock width knob around 11 o'clock Then experiment with the freq and width knobs - try anywhere between say 9 o'clock and 12 o'clock. This works great with distortion / OD / fuzz in the pedal chain or in the morphtone pre/post loop.

Morphtone signal path is designed to minimise noise so any noise in the signal is only likely to be emphasised with extreme EQ boost settings using the upper red EQ in peak mode. This is a reality with any EQ pedal filter capable of extreme high Q boost, whether parametric or graphic. In this type of setting, if you are staging morphtone after any very high gain pedals (i.e. the sort of pedals which may be inherently noisy) it can help to use a noise gate, or alternatively try putting morphtone before your high gain pedal for a different kind of driven tone, and this will avoid applying boost to the noise generated by your high gain pedal. Also it can help to optimise 'gain staging' which is the process of setting each stage in your signal path to output the optimum signal for the input of the next device in the chain. Set the pad switch appropriately for your input signal level and the output level control knob to match whatever amp or other devices are in the signal chain directly after morphtone.

Well maybe not asked frequently, but at least once so... No, knobs are not motorised, but our video demos animate the knob positions using special magic unicorn dust 🦄 so that you can clearly see how to set up your morphtone for different applications.

The shopping cart operates a live stock system so if stock is showing as available to order - then we currently have stock available. We try to maintain a level of stock available when possible however sometimes we may temporarily sell out. This is likely to be normally only for a short period of a few days at most. If a product goes out of stock for any reason e.g. we are waiting on parts, we can notify you as soon as stock is available again.

As we grow, we plan to make our products available in an increasing number of territories, we do not have a public plan on rollout but we are working on this.

This is not a service we generally offer at the moment, but if you have a special requirement you are very welcome to enquire in case we may be able to help.

Pedals are covered for 12 months for the original purchaser in the unlikely event of manufacturing defects or component failure (not misuse). Warranty does not include paint or finishing, any damage caused by misuse, lost knobs, or the use of an incorrect power supply. Any warranty repair will be subject to an inspection upon return and we will contact you if there is any issue that prevents us from undertaking repair under warranty. So if you use our products as intended and something goes wrong, we will fix it free of charge (other than the sender paying cost of return postage to us). Warranty is void if the pedal has been modified or otherwise tampered with. Always contact us before returning any pedal for repair. We strongly recommend posting by recorded or special delivery and are not liable for any return item which you send to us that does not arrive.

In the unlikely event that you ae not happy with your purchase, you can return it within 14 days. In this case, firstly contact us as soon as possible. When we receive the pedal back in the condition in which it was sent out to you and without any damage, cosmetic or otherwise, with all original packaging, we will issue a refund. It is the buyer's responsibility to ensure that any return arrives back in perfect condition. Unfortunately we cannot refund return postage costs. Remember to send pedals by recorded or special delivery as we will not be liable for anything you send that does not arrive.

At this time we operate Muir Audio Design as direct-to-customer. This may evolve over time but please free to contact us.
