Custom Cornerstone Tenor Ukulele


Circa 2022. Preowned. Beautiful Custom Cornerstone Tenor ukulele handcrafted with the utmost attention to detail by master luthier Peter Marreiros in Westminster, California. This gorgeous Custom Cornerstone Tenor Ukulele is truly a wonderful instrument and comes highly recommended by fans of Cornerstone ukuleles worldwide. A career luthier famed for his extensive experience in guitar luthiery, Peter has taken his woodworking knowledge and passion for finely handcrafted instruments and applied this to beautifully crafted custom ukuleles for your enjoyment.


Peter Marreiros embarked on his lutherie journey in the late 90’s. In those beginning years he built a few electric guitars. In 2003 he was inspired to build an acoustic guitar. During this process he realized this was his true passion. The demands of building an acoustic guitar were far greater and spawned deeper levels of creativity and detailed workmanship.  Little did Peter know that same year he would meet legendary luthier, Kevin Ryan where both sons were playing little league baseball together. Their friendship grew and Kevin’s meticulous mastery and artistry became a goal for Peter’s builds. Peter’s attention to detail pushed him to build high quality instruments that were aesthetically stunning, uniquely designed, and embodied a strong musically appealing tone.

Peter’s interest for ukuleles was sparked during a visit to one of his friends in the winter of 2018 and coincidentally a trip to Hawaii in February of 2019 further enhanced his interest for the small happy instrument. Pairing years of guitar building experience with his new found love is what drives this builder to push the boundaries of lutherie with a vision to build a ukulele like no other.

“It is with passion and love that a Cornerstone Ukulele is created. Each of my ukuleles is handcrafted and every instrument is a labor of love and dedication. My desire is for my passion to fuel yours…”

This gorgeous custom Cornerstone  Tenor Ukulele is a fantastic playing and sounding instrument. The body was handcrafted from a master grade set of Australian Blackwood, which is in the family of Acacia woods as is Hawaiian Koa. The quality of the Australian Blackwood used on this ukulele is some of the finest available with a tight grain curl in the wood and gorgeous dark vertical streaking with a touch of sap wood on the top center of the back of the instrument. The fretboard was radiused for ease of play in the higher positions on the neck and hand carved from a master grade set of Gabon Ebony wood, consistent with the finest materials available for ukuleles. The fretboard was also elegantly bound in Ebony wood, making for a smooth glide of the player’s hand up and down the fretboard. Ebony wood bridge and a solid one-piece wood-stained Mahogany neck for added stability and transference of the vibrations back into the sound box. Gorgeous paua abalone shell inlay on the soundboard, fingerboard, and headstock with a beautiful oval design soundhole with Chrysocolla reconstructed stone rosette – this uke is absolutely stunning! Wonderful half-headstock “Tribal tattoo” sail design and matching rosette done meticulously in Chrysocolla reconstructed stone with a white colored Cornerstone logo in reconstructed stone. Chrysocolla is a blue green crystal with a high copper content and is opaque in transparency with a vitreous to dull luster. The meaning of Chrysocolla is communication, teaching, and transformation. It is calming with is blue and green colors and captures the soft serenity of still water on a golden summers day, inviting you to tune into your own sense of wonder and knowledge – giving you those tools you need to become your own greatest teacher.

The instrument also boasts a Chrysocolla tribal inspired inlay of reconstructed stone centered at the twelfth fret for quick and easy reference when playing. Bone nut and saddle in keeping with the elegant theme of old world tradition. Spot on intonation with a 14 fret joint to the body with 19 overall frets to the sound hole. The instrument also incorporates a uniquely designed hybrid Kasha bracing with hollowed out core and triple hole side sound port on the upper bout for a ‘monitor-like’ effect. Jet black Gabon ebony wood top and back binding with a top beveled armrest for added comfort when cradling the instrument. Professional and custom made Gotoh open-geared machine tuners with black buttons for precise and smooth tuning. String through bridge design for a functional yet elegant feel. A high grade durable polyester finish on the body and neck give it a mirror-like sheen that reveals the natural beauty of the wood.

This is a true masterpiece of functional art that is both appealing to even the most renowned professional ukulele musicians and the recreational player alike. This instrument has a lovely warm and balanced sound with excellent projection and a vibrant response. A highly recommended ukulele for both the professional musician and the ukulele enthusiast at heart. ID#230108
