Holton TR180 Bass Trombone from 1972. This is the model that professor Lewis Van Haney, Indiana University like to play on the most. The valve configuration is rotor dependent Bb/F/bE tuning. Simply put, the first valve is like an F trigger on a tenor. The second valve only functions when the first valve is in and the not produced in first position is a flat E (Not D or Eb, but a flat E). The purpose of the second valve on this model is to allow the player to play a low B in 7th position identical to the B one octave above it as played on a tenor in 7th position without any valve. A low C can then be played with both valves in, with a slightly raised 6th position. This is a very simple and intuitive approach to bass trombone, ideal for a tenor doubler. Fresly Cleaned and serviced, chemical bath, flush, valves removed cleaned aligned & adjusted for maximum playability. Handslide has been realigned and adjusted. No chrome wear on inner stockings. Has 10" Rose Brass Bell, Standard LT Nickel .562 bore bass slide.
