I have had the luxury of playing many different trombones. What I like about this horn is the sound and the comfort. This horn sounds like a trombone is supposed to. The size of the braces and the shape of the tubing in conjunction with the balance and weight of the horn make it a bone that will not tire me out.

I apologize for claiming in my 5 Star review that the 4501 is a "dual-bore" horn. It is not. In fact, it is a .500in standard-bore bone, however this is the only correction and all else in review stands as written. I do love this horn....

This Urbie Green model (4501)is: 1- high quality; 2- beautifully designed; 3- lightweight; 4- well-balanced; 5- nicely detailed (Note curved handgrip, SOLID slide grab rail & wide rubber bottom slide bumper that looks great & is a nice touch, not metal nippled like most). 6- a dual-bore slide tube design and I love the solid metal grab bar. I am spoiled by smooth, quiet and responsive glide slides and this bone has it; 7- bright & earthy toned throughout and gives me smooth transfer up & down the registers. 8- I like to blat & splat down low and this bone vibrates. Gotta love it.... 9- The small shank cupped Bach 12 mouthpiece is complimentary and well-matched. 10- The spit valve is responsively sprung & tight with a nice long lever; 11- as for the case- not the best I've had (room for mutes & music mainly), but is well thought out & sturdy, plus, you can access the storage bin WITHOUT having to unstrap the bell section! The whole assembly lifts right up. Another nice touch. 12- I strongly recommend using the two component Slide-o-Mix slide lube. It is the highest quality treatment I have EVER come across! It's a German product and it makes a great slide better. I couldn't believe the difference over silicone or other treatments I've tried since 1962. It cost me about $13 bucks. I have tried out vintage horns, the King 2 & 3B's (Standard and SilverSonic), the Vincent Bach Strad family (12 & 16 and the LT16M) and frankly, I was not romanced by any of them. Don't get me wrong. These are fine expensive horns, but I figure you have GOT to absolutely fall in love with such a costly bone and I didn't. Anything that comes in contact with my mouth had better give me a thrill and this little Martin cutie did it at first sight and blow. I have worked with first rank symphony and opera orchestras, and have many friends in the business. So I am accustomed to live, un-miked instrumental sound, tonal quality. I have been looking for the right horn partner for 2 years and I feel I have found her at last. Worth the wait.......

I am the least qualified trombone player and reviewer to judge or deserve the pleasure of playing this instrument. Hadn't played trombone for fifty years after disappointing parents, band director and band mates, quitting it in HS for sports, college, medical school etc. etc. Bought my TR4501 after three months as a 'recovering trombonist' invited to join my town's band. After discovering long lost skills with a borrowed Conn H48, trying other new and used Conns, Kings, Yamahas, Blessings & Bachs at garage sales and music stores I bought an Urbie Green on the basis of the reviews and its design without even touching one.I just love this thing. It has a character, a feel, a "soul" to it which speaks to me and, I swear is teaching me to voice its song. My new bandmates do not believe I haven't played for 50 years. Play this horn and see if your musical soul may find voice in it, too.

I have played King, Bach and Conn for many years. The "urbie Green" trombone is better than all of them. The slide is amazing, the tone is smooth, but bright when I want it to be. No matter how hard I blow the horn can take it and asks for more. The partials slot very well. I don't think one can go wrong with this horn.

I wrote a glowing review of the King 3B Silver Sonic several months ago, which is one of the greatest trombones ever made - ever! That being said, the Martin is also another truly amazing trombone. I waited far too long to get a trombone with an ultra-light slide. If you think your technique is good with a "regular" slide, you must try the Martin. I always play larger bore horns and want a big sound, and the Martin is the smallest jazz horn that you can really rip in both high and low registers. It is also extremely light. If you are older and have shoulder and elbow "issues" (like me), this horn is feather-light. You can play a 3-hour dance gig with much less pain and effort - and the Martin is absolutely balanced. I use my Dennis Wick 6BS with the Martin - and it really delivers!

I play the Holton/Martin, Urbie Green model 4501professionally and find it to be the best trombone I have ever played. The slide moves like'glass'. I highly reccommend this instrument.

Urbie Green knew his thing; this horn is exquisite. I've been playing on a 1938 Martin Handcraft Committee Tenor for two wonderful years. Martin horns are well known for their quality, which is why people such as Jack Jenny, Miles Davis and many others favored them. The curved handle is quite comfortable -- allows for a secure grip. The slide is like glass. As most have mentioned this horn has very accurate response and smooth transition between partials no matter the dynamic level. This Martin can project your sound out in a crowd or into a mic with utter ease. A perfect media for any jazz player. Also, if you have an old Martin Committee with a good bell section, it fits perfectly to the Urbie slide section, it even screws together. So if you've an old Committee you can bring it back to life. Which means, if your old schooler has a 7 bell, you have your own version of the new Martin Dave Steinmeyer. This is what I found out with my own setup, I cannot say for sure if it will work with yours, I could just be biased and lucky!Enjoy your shopping.

Love the flex and the possibility to play with very open sound and lots of air without loosing power.

The Urbie Green model Martin TR4501 trombone is one of the most well thought out instruments I've ever played. Know primarily as a jazz horn, itis also very versatile. This should be no surprise, for Urbie Green had to play anything and everything as the top studio trombonist in New York during the 50Æs, 60Æs, and 70Æs. From the poppingÆ pedal tones to the singing stratosphere it is free blowing and focused, with great projection and pitch. It is very lightweight, yet has a big, full tone throughout the range that maintains flexibility and control. The slide is amazingly smooth and fast,with a smaller handbar that adds to the ease of its speed and reach. The curved left hand grip is another comfortable feature, as is the chromedgooseneck and larger water key. Versatile though it may be, this trombone just exudes jazz. The Martin sounds great in a microphone or in the room, and easily shifts from as smooth to as gutsy as you want to go. It is my favorite small bore horn because it does exactly what you tell it to do. What an absolute joy the Urbie Green trombone is to play!
