Conn 18B 1980's Student/Intermediate Trumpet

Key Specs (1980s version)

• Bore: Medium-large (ML), typically ~0.460″.
• Bell: 5″ yellow brass (standard lacquer finish).
• Construction: Made in the USA (primarily during the later Abilene, Texas production period and into the early UMI/Eastlake transition). Features piston valves (often with updates to two-pin guides in later examples), Amado-style water keys on many, and typical student bracing.
• Production window: Appears in Conn’s 1986 catalog (with “36” prefix serials noted in some records); discontinued by the 1988 catalog and replaced by the 20B. Examples exist from the late 1970s into the mid-1980s (e.g., 1979 and 1984 documented examples).

Context and History

The “18B” model number was reused by Conn across decades:

• 1920s–1930s: Professional-oriented C/Bb/A models (smaller bore).
• Mid-1950s–1960s: Early Director student models (often with Coprion bells on the 18B, ~0.438″ bore, “Shooting Star” engraving on some).
• 1970s–1980s: Updated student Director (ML bore, 5″ bell).

In the 1980s specifically, it was positioned as a durable beginner-to-intermediate school band instrument. Serial numbers from this era for student trumpets often use an “S” prefix (e.g., S-prefixed numbers in the 08xxx–38xxx range for late-1970s/early-to-mid-1980s examples) or other systems from the HA-series period; exact dating can vary because student lines sometimes used separate numbering.

Playing Characteristics

These are solid, playable student horns when in good condition (smooth valves, free slides, good compression). They offer a brighter, more projecting sound typical of Conn Directors and are commonly found with original hard cases and mouthpieces (often a 7C-style)
