Alright guys, so my new Rebop 5 in white just came in. Great looking bass. Like all of you said the action from the factory was too high. After adjustments were made, it played beautifully. Again, like you all said, the string spacing was closer than I'm used to, but it actually forces you to be more articulate and precise in your playing, which is good. So, I'm jammin on it and I'm really diggin' it a lot. Then. I go to plug it in. ERRRRRRRRRRRRRR! Very weird and annoying buzzes that are way out of the ordinary. So, I called PJ at Spector for help. Says there are some blown electronics in it. Great guys to deal with over there. Now, he gave me some options which is where my question lie. This one is equipped with the Aguilar OBP-1, vs. the newer Tone Pump systems. Apparantly, when I ship it back to New York for a swap out, I could put in either one. Which sounds better? Anybody have experience with the new Tonepumps Vs. Aguilar Pre's? I'd appreciate the opinions on what you like better.
