I agree with Geoff about one bass. All the greats (well most) on almost every instrument have one main axe, look at yoyo mah & jaco. On a side note the hart is a lovelly instrument & a great choice for a main db. I would love to hear it, you should get someone at your shop to take a video of you playing next time you have her out for practice or rehersal so we can hear it ken.
