Signature series mouthpiece from the Spanish brand "Romera Brass". Offering the SC48L, a highly sought-after model from the SC series, similar to the Helberg model and very popular. Inner diameter 32.5mm / Throat 8.3mm / Depth 48.0mm American shank Features a beautiful and precise construction, with a rich and smooth sound. Handles high volumes and allows for nuanced expression. I'm selling it because I often play in orchestras and have started using a slightly larger mouthpiece. I believe it's in beautiful condition. Please take this opportunity to acquire it.
