Intermediate Tenor Trombone
Excellent ease of use and great sound. Nice case and excellent condition. Great value for the price.
This is a very nice horn. It is well built and not at all like many "cheap" instruments that are made and sold. Both quality and pride are evident in the TB400 Trombone and the people that represent Jean Paul Wind Instruments. The customer service is outstanding. I ordered this horn from amazon and it came with two small dents in the bell, due to the mouthpiece not being secured in the case. I contacted the Jean Paul Company directly and not only did I receive a phone call from Tim, one of their representatives, less then 48 hours later, but he shipped me another brand new horn which I recieved 3 days later. He also continually texted and emailed me to update me on the status and also provided me the tracking number as well. He also provided the return shipping label to return the damaged horn. I just simply took it to a CVS store and dropped it off for UPS to pick up and ship back to them. He then made sure i was completely satisfied with the brand new one they quickly shipped to me. He also updated my warranty information for me. This company has impressed me with both the product they provide and the personal service they extend to their customers. The horn sounds and plays very good and again is very well built. The case it comes in is also sturdy, attractive and effective in keeping the trombone protected and transported with confidence. I am most pleased with this instrument and the company that stands behind it.
