A pupil at an Edinburgh school has designed an eco-friendly guitar that can switch between acoustic and electric sounds, allowing musicians to change tone without needing multiple instruments.
The design uses interchangeable components to alter the guitar’s sound, removing the need to buy multiple instruments and helping reduce material waste.
Chester, aged 19, from Edinburgh, began developing the idea after noticing how expensive it can be for musicians to own several guitars to achieve different sounds.
He designed a single instrument capable of producing multiple tones while also using more sustainable materials, including FSC-certified wood and water-based finishes. The design also allows parts to be repaired or replaced rather than the whole instrument being discarded, helping reduce waste.

Chester said: “The guitar’s most unique feature is a removable modular block which houses all of the electronics and pickups. Different pickups create different tones, which is why musicians often need several guitars to achieve particular sounds.
“With this design, guitarists can swap components and customise the sound of the instrument, even mid-performance.”
Working on the prototype for more than a year, he experimented with a range of materials, from traditional timber to experimental resin, before refining the final design. The result is a fully functioning guitar that can be adapted for different styles of music.
Florence Chapman, Head of Faculty for Technologies and Creative Arts and Design Technology teacher at Merchiston Castle School, said: “This is a brilliant example of how the disciplines within STEM can work together to complement one another in producing a single creative outcome.
“Chester has used knowledge from subjects like maths and physics alongside design and music to create something genuinely innovative. Projects like this show how pupils can take an idea, test it, refine it and turn it into something real.”
Music lover Chester added: “I’ve played guitar for about six years and realised that musicians often need several guitars to achieve different sounds, which can be really expensive.
“I wanted to see if it was possible to create one instrument that could produce the sound of many guitars while also being more sustainable. It took a lot of trial and error, but seeing the final guitar working has been incredibly rewarding.”
The guitar has already been tested by fellow pupils and teachers performing classic rock tracks in the school’s music department.

Chester added: “I play in a band with my friends at Merchiston called Sleet. We play 80s and 90s rock music, including Smashing Pumpkins, Radiohead and Red Hot Chili Peppers. It would be amazing to see John Frusciante play this guitar one day.”
Chester, a senior prefect at the school with a strong interest in both STEM and design, plans to study Design Engineering at university.
He hopes to continue exploring the intersection between design, engineering and music in the future.
