Hey So one of the things I need is a new cable. I have a P Bass, a J Bass on order, and a Stingray. So that means I have 2 that need plugging in on the front and 1 that needs plugging in on the bottom! Do I get an angled cable? Daft Q, but does using a angled cable 'work' or a Pbass/Jbass....eg will it mark the paint when im playing? Secondly, the best length? Id like length to walk about with....is 20ft just about right? Or will 30ft be better? Ive heard 30fts can start to affect your signal.
