OK I do play some trumpet...and this person asked me this question..but I am not knowledgable enough to give her the proper answer...I would like some help. Thank you. Hello, could you give some information on the tone difference between a model 37 Strad and a 43? Since you are a trumpeter I thought you would know. Also is a reverse lead pipe easier to blow? Thank you. I played long ago and am interested in a Strad. I have a Conn Connstellation.
