The Thomann EP 802S Superior Euphonium is well-equipped to meet the needs of modern players. It incorporates four non-compensating Périnet valves, which eliminate sharp bends in the wind passage to keep the airflow smooth. The dual bore diameter extends from 14.5 to 16.8mm. The body of this instrument is crafted from copper. This material ensures extreme durability. The nickel-silver outer slides add lustre to the EP 802S. The instrument features three water keys for appropriate adjustments in the pitch. The EP 802S package includes a mouthpiece and a lightweight form-fitting bag with backpack straps and castors.
