I'm kind of in a bind here. My jazz band just demanded a double bass, but I don't have a pickup for mine yet. I want to make sure I sound good, but don't have a ton of money to spend. I have a beautiful Quenoil (Q-model) replica and am going to be playing mostly big band stuff. At this point, I'm looking at one preamp and pickup especially: Pure Preamp (by K&K Sound) Double Big Twin (by K&K Sound. The one with the four headed bass transducer) Am I just settling for these or are these actually decent products? I don't want to spend more than $200 on the combo, and if I buy these on ebay I can get the whole package for like $180. This seems perfect, but are these good products?
