We're all different. I don't need (or use...) an amp or cab for practising guitar or bass, just the instrument, and I've got several of each, so... And I'm long past 'practising' drums; I did all that decades ago. I just listen to the track that needs learning, then go and play it. S'what comes of being old, I suppose. It's true I wouldn't leave my stuff unattended in the village square for weeks on end, but other than that, I've never had a problem with stuff being nicked. S'what comes of having unpopular gear, maybe..? The bass amp and cab that we use most have enough mass between 'em to bring the Moon quite a lot closer, so no-one is going to be 'lifting' them and legging it..! In all the festivals I've helped organise and/or played at, I've never once come across a case of stuff 'going missing'. Just lucky..? Perhaps, or folks where we live are less on the look-out for committing larceny.
