It's a fact that most UK brass instrument retailers cannot afford to stock the amazing range of horns from bespoke craft manufacturers, I guess due to stockholding costs. Basically you can only find Yamaha, Bach and B&S in many stores - ofcourse these are all very fine instruments.
We could do with a Guitar Guitar trumpet version superstore - Edinburgh would be fine for me. Or we need a new business model that could facilitate offering a much wider choice. My friend, Bristol trumpeter Trevor Jones, has one of the widest selections of instruments here in the UK.
