USED Kalison KAB77 professional 4/4 CC tuba in silver. 4 pistons with 5th Rotax rotary valve. Very good condition with minor dings, dents, and scratches here and there. The is evidence of previous solder work where the tubing was re-configured to improve intonation, but it does not look bad at all. This tuba was just cleaned here in our shop. Includes brand new TE gig bag!
