The "db" (and the controller) is suitably retro and reminds me of a time when Atari was king, but the upper-case "F" just doesn't fit. (I know, you didn't design the font.) What I would suggest doing is making it a more ordinary gothic (sans-serif) "F" by erasing the curved parts and replacing them with straight lines (or edit the shape if you're working in vector format). Use the max width of the "G" as a measure of how long you'd want the upper cross-piece to be. That will allow the "G" to kern in neatly under the upper cross-piece. One of the deals with logos is that the fonts you use are usually just a starting point; you need to worry more about the internal consistency of the logo than about the consistency of the overall typeface. (There are no Bs, Ps, Rs or Js to balance the F off against, so make it a match for what is there instead of for what isn't.)
(I'm not a fan of the colour either, but that might change dramatically in the context of the page design.)
