I thought we should include Marcocolo's modifications to his Mikro in part 2:
My Mikro
--------------------------------------------------------------------------------
I thought I might add my project to the list here. Hopefully this will aid others who want to upgrade their Mikro.
First thing I did was the bridge fix- shortening the screws and the springs. Then I cut the nut down to lower the action. This should be done by someone who knows what they are doing. And it did make a significant difference w/ the playability. Then I filed the fret ends to make it nice and smooth on the hands. Next, hit the fretboard w/ a couple doses of Gerlitz' "Guitar Honey". Great stuff.
So far no $ involved. I'm really liking this little gem and I felt I can live w/ the bridge and tuners for the time being. Electronics next.
Researched here and elsewhere the best options for a P/J. Listened to many clips of PU's. Was most concerned w/ getting a P that I would be really happy with. Wanted "vintage" sound. Also wanted both PU's to be silent.
Finally decided on the Seymour Duncan SPB-1 and the DiMarzio Area J (humbucking) combo. These I feel offer the best bang for the buck and actually the more I hear them, maybe for any bucks.
Ordered some Bournes 250K pots w/ 1/4" smooth shafts and got a 49 mf cap from a friend. Lined the control cavity w/ copper foil. Wired it as per SD site VVT configuration. Found some cool J bass tone knobs for all the controls. I think the smaller knobs go really nicely w/ the Mikro's small body.
And what about the 4th knob , you might ask? That's a "Certainbass" Veritone that I thought I'd try out. I had to use my Dremel sanding wheel in the control cavity to get it to fit. Took all of 10 minutes.
Lastly, added some GHS "Bright Flats" that someone in this thread recommended. I'm already a big fan of GHS's flats (have them on 2 other basses). On this bass I thought that w/ the J PU in the mix, some hotter strings would allow me to get a little of the Jaco thing going. Don't like rounds so......
Also, these strings have really nice tension on the really short scale of the Mikro. I know a lot of players complain that short scale basses have floppy strings. Not so w/ these.
End result? This mod took a nice sounding great little bass to the level of an exceptional sounding no excuses what-so-ever bass. REALLY. There is absolutely NO comparison between the original PU's and the new ones. P bass PU is as good as any I've heard. The area J sounds like a very good to exceptional bridge PU w/ zero hum. Without even touching the amp, I've got 5-6 really nice ,usable different sounds- a claasic P grind, classic J, the combo of the 2, a very good cop of Jaco thru the Veritone and a good cop of Jamerson thru the Veritone . And I haven't even experimented much so far. Actually, now the bass is dead quiet.(a pet peeve of mine).
So, $180 up front, $180 for the PU's and the Veritone and $40 for the strings and the pots, etc. For about $400 I've got a bass that I think, IMHO, sounds as good as just about anything out there. Well worth the time and expense.
