I recenty bought a bass buggie to help me get around town. However, my first few trips out with it haven't been very successful - the bass does not sit very stably in it, and it keeps rolling around. I find myself having to fight to stop the whole contraption veering off to one side. Has anyone had this issue before? I thought I might be adjusting it wrong but having seen the (admittedly rather sparse) user info I'm not so sure. There is a significant gap on either side between the bass and the buggie - do I need to pad it with something maybe to get it fitting snugly? I'm quite frustrated at the moment - I used to have an endpin wheel and could walk my bass to the gig and have a hand free to wheel a suitcase containing amp, stand etc. with my free hand. That's not possible with the buggie at the moment, and it seems I've gone rather up in cost for such a drop in functionality..... Any input gratefully received!
