The Decibel Eleven Hot Stone SMD is a high-quality power supply that will provide clean, reliable power to up to 8 of your pedals. Featuring isolated outputs, thorough magnetic shielding and an incredibly robust enclosure, this power supply is a tour-worthy option for professionals.

Designed for smaller pedalboards, the Hot Stone SMD has a compact design that can be easily mounted beneath boards from top brands such as Pedaltrain. With 6 of its outputs fully isolated, this ensures that no hum or interference will occur between your pedals, keeping any noise from your rig to an absolute minimum.

With two 400mA sections, featuring outputs rated at 9V and 12V, these will deliver enough current to power demanding modern digital pedals, including those produced by Strymon, Eventide and Line 6. With cables included, you can start wiring up your board straight away!
