I've just bought a used Ibanez Gio 6er and am really impressed with the build. Can't believe I stole it for $100. I've tested the Ibanez SR505 and SR5 5 string basses and while the build of this Gio is (surprisingly) as good as the 505's I've tested, I know that the pickups and/or the electroincs in the Gio aren't anywhere near on the same level as the mid priced SR5 and 505 which come with Bartolinis and who knows what preamp. The preamp control configuration on the Gio is a little unusual as there are two volume controls, a master tone and a "bass boost". So other than the bass boost and being an active system, there really isn't much that it offers that a passive system doesn't offer. And I can tell just from the look of the pickups, they look very much like the ones on ebay that you can buy two for $17. So what would you try first to make the sound better? Preamp, pickups or just live with it and get an external preamp or a good EQ pedal? Thoughts? Suggestions?
