So I bought a set of GHS Bass boomers yesterday, cuz my current strings are in need of a change. But the problem is, I don't really know where to start and I don't want to screw up, bass strings aren't cheap you know. So do I take them off the headstock or the bridge first? And how do I get them loose from the bridge? And how do I get them in on both sides? I have an Ibanez SRX300 with a B100 bridge, if that will help any. Thnx in advance.
