Diablo Tuba Mouthpiece

Diablo Tuba Mouthpiece – Our Top-Selling All-Purpose Beast

Inner Rim Diameter: approx. 1.295" | Throat: .318" | Cup Depth: Medium-Deep Funnel

Named after the fierce Diablo winds — the Northern California version of Santa Ana gales that roar down the East Bay hills at speeds over 60 mph — this mouthpiece unleashes that same unstoppable power in your playing. As our #1 bestseller for good reason, the Diablo is the ultimate workhorse for CC/BBb contra bass tubas (and shines on large 6/4 F/Eb too): medium-large size with a funnel cup and slightly tighter throat that delivers an intense, focused sound that's ridiculously easy to produce and pure fun to play. You get massive projection without effort, razor-clean articulation, secure slotting, and balanced tone that handles everything — from orchestral thunder and big band punch to solos, chamber, and everyday gigs. It's the perfect sweet spot: big enough for serious low-end authority, agile enough for speed and nuance.

Why players can't stop raving about the Diablo:

• Versatile powerhouse — Crushes nearly every situation on CC/BBb (and large F/Eb) with ease
• Intense focused tone — Funnel cup + .318" throat for concentrated projection, clarity, and bite
• Effortless & fun — Super-responsive, quick attacks, and fatigue-free play — just pick it up and go
• Balanced projection — Big sound that cuts through without strain or mud
• Built tough — Stainless steel means zero allergies, no wear, plays like new forever

If you want one mouthpiece that does it all with power, precision, and joy — the Diablo is the crowd favorite for a reason. Intense like the winds it's named for, yet totally controllable. Your go-to upgrade is here — grab the Diablo and dominate every gig!
