Born out of need and intuition, the TOOB ultra-portable speaker cabinets for guitar, bass and other musical instruments represent the pinnacle of innovation. Our Mission is to improve the quality of life of active musicians, whether student, amateur or professional.

In 2007, newly retired jazz guitar enthusiast Markku Pietinen picked up a piece of corrugated, double-wall plastic pipe from a construction site. Why not use this strong, light and ubiquitous high-tech material for speaker cabinets? The first TOOB prototype came together quickly, but it took a decade to perfect the innovative design and bring it to the market. While ultra-light Class D micro-amplifiers had conquered the bass amp market years earlier, they became a serious option for guitarists only around 2016. Today, more and more guitarists choose a solid-state amplifier not only for portability and carefree operation, but also for their excellent tone.

Launched in 2017, our 12J and 12R original guitar cabinets thus spearheaded the megatrend towards lighter musical equipment. A bass version, 12B, soon followed. The unique design has lent itself to numerous further variants including 10”, full-range as well as one-off Custom and Telescopic models.

Listening to prayers from New York jazz musicians, we introduced the public transit compatible, yet stage-worthy Metro 6.5” line in 2020. Another TOOB revolution – cute but not quiet! Now, equally compact but even louder Metro 8GP.

Next, we returned to original calibers and gave the enclosures back panels with felt-lined sound ports, another TOOB innovation. The 10S and 12S (Synthesis) models land tonally right between the guitar originals.

Countless prototypes (not all the frogs you kiss turn into princes) and soon 900 finished products have emerged from Markku’s workshop in a Helsinki suburb. Nearing 80 and working alone until recently, he’s backed by family and, importantly, a network of committed experts and suppliers.
