After 3 years or so of playing EEb bass , I'm giving Baritone a try again after some player moves. The band instrument is a Stirling , fairly free blowing ( at least based on one nights experience !! ), smallish bore ( I think but it would be coming from bass!!) but comes with an old DW 6BS. Was a reasonably comfortable blow but thinking I could do with something larger and deeper. Been having a google this morning and the DW / Steven Mead SM4 Ultra looks as though it might fit the bill. Anyone out there using one ? If so , what are the advantages / disadvantages thereof ? What sort of price range is reasonable ? All advice welcome !!
