The A4 trumpet is one of the most popular models in the B Flat trumpet line. The result of extensive collaborative work with Adams Performing Artist Amik Guerra. This is one of the heavier models featuring a 140mm (5.5 inch) one piece bell and a heavy bronze and nickel silver block.
An ideal choice for the soloist looking for an extremely rich, warm, fluid and thick sounding horn. Whilst most people order this trumpet in the larger 12mm bore, it is also available in a ML version on request. The A4 trumpet is also available in a shepherds crook model allowing for further customisation.
