I have made some changes to the TL5 for 2004. I have opened the bell taper a little to aid in the upper register. This will allow for a more open feel as you go up. The TL5R (red brass) will also have the more open feel but the red brass bell will allow you to push the dynamic a little further before the highs kick in. Both Lawler TL5's are full bright sounding trumpets with strong highs and mids in the sound. The very fast response is evident as in all Lawler TL models. The 1A leadpipe will give you a very centered feel with good slurs. The number 5 bell rim is a full 5 inches. The TL5 is available in .460 and .464 bores.
