Dept. 10 is the Blackstar R&D team responsible for blue sky innovation and design. This team of engineers are all musicians and are constantly researching new ideas to help create your perfect tone. They have developed the world’s most advanced valve pedals. Dept. 10 pedals all use an ECC83 triode valve at their heart, running at more than 200V internally which allows them to deliver organic tone, dynamics and break up. Innovative design, premium components and our advanced Cab Rig D.I. technology, create the ultimate valve pedals.
