I do think when getting lackadaisical of the gear I use, say, if I buy something new I will play MORE and spend more time with the bass, and if the gear I just bought invites you to go creative with new sounds, or new music, I will automatically be drawn to a certain playing style I haven't done before and play a lot more. Of course, that honey moon period will have its end as with most other things. Basically, I will detect new things with my playing that I wouldn't otherwise. By and large: It gives me a reason to play more. Investigate. Drink and swim in it for a while. To see what paths it leads me into. Curiosity. And as the fringe benefit I will - perhaps - come up with some new tunes, and songs, not endless disjointed riffs or licks. But in the end, regarding basses, guitars. It's one in and one out!The don't pile up and collects dust under the bed, or in the closet.
Basically: It inspires me!
