Making my Miami blue guitar MY Miami blue guitar

Some of you might remember that I posted a NGD ten days ago ... I got myself a Miami Blue American Pro II strat HSS, and very happy I've been with it, too.

For the first week of ownership, I did my usual decking the trem and getting the relief and action where I wanted them, and then put some real time in playing it (I didn't have much work on, and what gigs and practices I had I used the new one for). I haven't put it down much.

This allowed me to make a few observations, and get an idea of what, if anything I might want to change. There were only a handful of things.

1) The V-mod II single coils are great pickups, very nice sounding, BUT the treble bleed that Fender install on these guitars makes them sound quite thin anywhere around 6 and down.

2) I have aluminium grounding plates behind the pickguards on my other strats, and they're notably quieter than this guitar, stock when playing in front of my computer and camera/recording setup.

3) I'm much faster at fitting new strings on my guitars with locking tuners.

4) ... and this is the weird one... when the humbucker (a Fender 'double tap') is split, and you're in position 4 on the switch, the bridge tone control no longer has any effect BUT if you roll down the volume it still gets way brighter than it is on full chat.

5) I disliked how much the push/push tone pot that splits the humbucker would stick up, both when engaged and disengaged.

Then lastly, I started to think the mint green guard looked a bit wrong, and set the blue finish to look more teal, and it looked more plastic-y than my other strats. I really like 70's style black out plastics on strats.

Here's how it started:

So, I snipped out one of the PCB mounted treble bleed capacitor/resistor network for the single coils (there is a second one in these AM Pro II's on the double gang 250/500k piggyback volume pots), and replaced it with the 100k resistor and 102pf capacitor that I found to work great in my American Special strat. I left the humbucker pot with the Fender treble bleed, but added an extra 150kohm resistor across the lugs.

I shielded all the cavities with Titan RF blackout tape and fitted an admittedly overpriced Bareknuckle Pickups shielding plate under the scratchplate.

I put a second potentiometer nut and two washers on the push/push pot UNDER the guard, to bring the proud thread –– and thus the knob –– much closer to the scratchplate.

I fitted Fender locking tuners.

I closed it all up with some new black plastics. I didn't have a black strat switch tip in my parts bin though, just a telecaster version... so for now it's got one of those.

Pics were taken in the dark... will take better ones tomorrow if anyone wants a better idea of how a black guard looks on these Miami blue strats.

The black looks good, but I’m a fan of white plastics, and Miami blue is a beautiful color either way.
Thanks, I do like white plastics too, but this was quite an odd mint green, and the pickup covers and knobs were a very different kind of greeny-white. They made the blue look more teal.

I have a parchment guard in my pile of parts, I might try that one day, who knows... all of it is reversible :)

Looks nice! I know Miami Blue is a hard color to photograph - I had one for a while - but it seems like the black pickguard/covers/knobs make it photo a bit "bluer" than with the original greenish pickguard.

I agree, it definitely takes some of the green out. It's still nothing like the pics in real life, but a lot less green, nonetheless. I really like the colour. :)

Looks great. Congrats.
Thank you!

I'm intrigued by the circuit. When you say the bridge tone pot doesn't work in "P4", what exactly were you expecting? I suppose if it has a superswitch you could use one if the four banks to assign tone pots as you wish.

I could've phrased it better.

As the guitar comes, the tone controls work so that the top one controls the neck and middle pickup, the lower controls the bridge pickup.

In the 'in-between' position that selects the middle single coil pickup with the bridge humbucker, both tones work. Then when you hit the push/push to tap the bridge humbucker –– in the same position –– neither tone controls do anything at all. As such, with the stock treble bleed circuit in place, if you're in that position (which is a nice sound with the volume all the way up) and you roll back the volume, it gets unusually spiky and thin. You can't knock it down with the tone controls.

That doesn't sound right - the tones are supposed to work with tone 1 working on positions 2-5 (Fender convention is to number the bridge pickup only position as "1", so bridge + middle is "2", etc.) and tone 2 working only in position 1 regardless of how the push/push switch is set (i.e. either full humbucker or split using the back coil) per the service manual. So no interaction whatsoever between the tone pots in the stock wiring.

The one I had was SSS but that is how it works - of course the push/push switch adds the bridge and neck pickups together on the SSS. So tone 2 worked for position 1 regardless of if the push/push was set to bridge pickup only or bridge + neck, and tone 2 worked for position 2 regardless of if the push/push was set to bridge + middle or all 3 pickups.

See page 6 of the service manual for the Pro II HSS:


That description is sort of how the wiring on an American Performer HSS, Player HSS, Player Plus HSS works - but both tone pots should work in position 2 (bridge + middle) regardless of how the coil split for the humbucker is set. Here's the service manual for an American Performer HSS; see page 5 of it:

I’ve got a gig this evening, but tomorrow I will make a video to demonstrate. It’s not just mine, two at a shop a friend works at act the same exact way. Something to do with the double tap and how it’s wired, apparently.

The double tap humbuckers are never truly split, just tapped, hence the name. The Performer series don’t appear to have the stacked double-gang volume pot, either, or a treble bleed fitted as standard.

@John C –– here you go:



Thanks for posting; I'm not a wiring guy but definitely something off with the Miami Blue Strat vs. the sunburst one - even if the tones were working like the older wiring (tone 1 for neck & middle pickup and tone 2 for bridge pickup with interaction in position 2) the tone should be working the same way regardless of how you have your coil split set. Maybe the wiring charts on in the service manual for the Pro II can help.

This is it though, all the HSS Am Pro II strats appear to do it. The even more confusing thing is that it’s not that the time controls do nothing at all — if you have a high frequency hiss from a pedal or similar, it’ll roll that off some, just not the pickup signals.

I’ve heard it’s a capacitance issue and something to do with the particular fender double tap pickup in pro II’s — which is not wired like typical humbuckers (see other threads on the forum at the moment about how to replace them). They don’t actually split the coils like the older Pro series or my sunburst HSS. If you tap the coils with a screwdriver when plugged in the older ones will have just the back coil active — these Am Pro II have both coils ‘on’ but the sound has a markedly different resonant peak.

I like the sound of it, I just wasn’t totally happy with the treble bleed and it’ll take a while and a bit of experimentation to get it just how I like it.

I put black plastics on mine for a bit and it made it look more green than it does already (looked like a surf green) - reverted back to the mint green which imo made the blue standout more. YMMV.
I definitely see the opposite at the moment, but it's such an easy job to switch it back that it's fun to try and if I change my mind I'll make sure I tell you were right :)

I believe you; if that's the way they are working then there is something odd going on with the pickups and wiring. I'll admit that I am not a fan of HSS Strats so I've never really played an HSS American Pro II other than just to check out the neck shape. I'm going to have to find one and try it out and see what's going on with them.

My American Pro II was SSS - and the tone controls worked as it was supposed to per the wiring diagram, but then again there wouldn't be any capacitance issues with 3 single coils.

Nice guitar, Wulfrik! I just got one of those in dark knight. The first thing I did after purchase was order Fender Locking tunas! I have them on all my guitars for two reasons: 1. better tuning stability because of less windings on the posts. 2. much easier and faster to change guitar strings. Why locking tuners aren't included on the Pro II but on the Ultra/Elite baffles me mind.
