[quote name='Jam' timestamp='1479115117' post='3173944']Recently I've noticed some bad habits with my technique, mostly with my fretting hand. Rather than keeping my fingers curved they tend to be straight when I fret, pressing down with the pad rather than the top of the fingertips. [/quote]
Is this a problem that is [i]actually[/i] causing you difficulties when you're playing, or is it just something you [i]think[/i] you should be doing differently?
My experience of 50 years playing bass at all levels, is that I play with mainly straight-ish fingers and use the pads of my fingers. As do may top players on YouTube videos. As long as you can hit all the notes you need to hit, on time and without any stress to your hand I don't see any "bad habits" here.
You might need to use the top of your fingers if you are playing 2 notes or more at once, when you need more than 1 string to ring out, but for single notes, pads and straight-ish fingers is a standard technique.
Economy of movement is also an objective when your rehearsing or playing for hours. As long as you can switch between the appropriate techniques when required you're fine.
Also it's better to use 1, 2, 4 fingering for the lower frets. Don't use one finger per fret until you are so far up the neck that the fret spacing doesn't cause you to stretch.
