//Ugh sorry I hit the back button and it posted twice... If anybody knows how to delete one of them then please do so. I have a Toby Pro 6 bass that I really enjoy the playability and low action of it. The electronics are crap as far as I can tell (MightMite passive pickups and a horrible active preamp that is worse than just wiring directly to the input jack). I'd love to add some more tone variations to my bass and don't want to buy a new bass any time soon. I play through an Ampeg 4x10HLF and I just bought a Aguilar Tone Hammer 350 thinking this would help get a more modern sound, but this didn't help much. I'm still happy with the amp, but I know the weak spot it my bass's preamp and or pickups. I read on the forums a lot of success stories of people just installing a new preamp and loving their new sound. This got me wanting to buy the Aguilar OBP-3, but then I read this article: http://www.bestbassgear.com/ebass/gear/electronics/pedals/when-is-a-pedal-better-than-a-preamp.html that basically said the OBP-3 is going to be the same difference as the preamp already in my Tone Hammer 350... I always play with both my soapbar pickups fully on so from my understanding I wouldn't be getting any impedance matching and buffering benefits, and all I would get is a output level boost. So that made me think that maybe I shouldn't get a preamp. I am a complete noob to this stuff so I could easily be missing something else. My figuring was that since I have the Tone Hammer 350 already, then I'd be better off just getting some Bartolini pickups (maybe Bartolinis M56) and keeping my current crappy inbass preamp (that I always keep on neutral) just the way it is. Would just getting Bartolini pickups and no new preamp be a good idea?
