Both!! When time allows; she's a peripatetic sonographer and charges around the world working as a locum so joins a brass band/orchestra wherever she fetches up! She has a mint Ibanez (Soundgear?) fretless bass and small SWR bass amp... which I assume now sit under a cloth at her house in Auckland...
Every brass player I ever worked with showed me how to get the thing going but for the life of me, I could only get the dying cow bellow from brass gear, eh! Same with drums; every drummer I worked with also showed me the basics but my brain couldn't cope with four limbs doing different things...
