The build quality on the Bb/F is exceptional. It feels as you would expect a professional model to feel. The sound is a little more centred than the Bb. The valve has a free, quick and precise action and all the notes work well. The F side notes are great all the way down to bottom D's and the pedals below. The case has a very high specification (based upon the current Bach Stradivarius cases) and this also comes complete with rucksack straps for greater convenience. Both instruments represent excellent value for money and are ideal for the aspiring trombone player. I could get away with either of these on a Halle gig.

JP133LR - great first impresson and easy sound.

As a tuba player who wants to learn to play trombone I decided to buy JP133LR. After buy on I received it faster than expected. Package was appropriate and all items came in ideal condition.

I am writing my opinion in a break after playing trombone for first hours. The first day impression is very positive. It is very well balanced so grip is comfortable. Although slide and rotary valve needs some workout for smoother move, the tone and intonation is at surprisingly high level.The tone is full and dark, air flows freely, it sounds natural and JP133LR has very solid and reliable sound. Despite this is my first trombone I did not have big intonation issues when playing scales.

Overall after first day I am very satisfied with my purchase and have no doubts about reliability of this trombone. Thank you for being there and giving opportunity get good brass for reasonable price.
