Hey again everyone, After listening to those cocked wah sounds of Brian May, Mark Knopfler and instagram guitarist David Levi who uses that auto/cocked wah stuff cleverly with octave distortion, and discovering the Arlo and Eldred Cocked Wah mods on TDPRI, I've come to want some of that for my Strat. The thing has a "S90", or Strat-Sized p90 pickup, in the bridge, and I was thinking of pulling up on my push pull volume knob to immediately go to the bridge pickup (like the blower mod) and with the resistor and capacitor combinations of either the Arlo or Eldred Mods.... and then go straight to jack. I tried this "straight to jack" thing before, and it was suuuuper bright, mind you this was for a middle pickup (had a thread about it here!). For this mod, I'd like to at least *try* having the 250k load of the volume pot on it at least, while still keep that "blower" mod functionality: I can be on the neck pickup and then all of a sudden, with a flick of a P/P, I'm on the bridge position with some cocked wah sound. So, I thought of adding a 249kohm resistor in parallel to the Arlo mod capacitors+resistor combo in order to "simulate" the load of a volume pot. Of course I'll also try removing that resistor afterwards and hear the tonal differences for reference. If I don't like the Arlo, I'll try the Eldred too of course. Here's my P/P diagram, is it correct according to my previously described application? I got the Arlo stuff from Phostenix Esquire diagrams and I don't know if I "transcribed" it correctly to this push pull variation.  |

Your diagram looks OK, but as always, let's get a second set of eyes on it. But I question the extra resistor to simulate the load of the V pot- why not just leave the V pot in circuit, as per the Phostenix diagram, with the cocked wah setting?

I'd like to simulate the load of the V pot, but not the wiper. I'd like to have "preset" volume, tone and switch positions, and then pull up on the P/P and it immediately goes to a full volume cocked wah "boost" on the bridge pickup only. So it's like the "blower" mod, or straight-to-jack mod, but with the load of the volume pot (250kOhm) to control it a bit. Of course I'll try even without the resistor. However, I had this already in my mind, and after using it awhile, if it becomes too unwieldy, I'll connect it to the volume pot! |

Dire, The diagram looks good to me too. I had another that I can’t quite remember, I think it’s an Arlo mod and is just something for you to look at.  |

Dire,
Thanks😸😸😸,
But it’s too late. I went with a:
- Push-Pull Volume/Pull up for Series to the Bridge and Neck;
- Push Pull Tone/Pull up to place the Middle pickup Out-Of-Phase;
- a 12 way Varitone connected to the Tone part of the aforementioned;
- a 6 way pickup rotary selector.

Cool application as well! Arlo mod on every pickup position, and it disconnects the tone pot. I'll keep that in mind as well, especially if I don't want the bridge pickup "solo boost". Thanks for sharing frets! |

No problem!  Those mods are soooo good. Man that Strat must sound awesome. Just as awesome as it looks. Congrats! |

Good luck Dire and thanks for the compliment. I will post a pic when it’s done. I think your wiring will be just what you want.

I think this wiring will be working just as I imagined as well. Can't wait to try it out! All I have left for this guitar is to see if that blending out of phase knob works, which I have in my other thread. Oh yeah and then there's something about a fixed Q-Filter... but I'll get to that in another post. |

Oh yeah and then there's something about a fixed Q-Filter... but I'll get to that in another post. Something cool about an OoP blend is that you can get an octave sound with the amount of note fundamental you want...and unlike an Octavia pedal, it works on chords. Not sure how well it works with the neck and bridge positions, but it's really nice with the neck and middle on the guitar I have it on. It also depends on which pickup is louder. Your bridge pickup is higher inductance than the others, which generally means it would be quieter when combined with the lower inductance neck pickup. Assuming the magnetic power isn't much stronger and/or it's not adjusted much closer to the strings, it should offer good versatility in adding in some note fundamental to the octave. Although, I think it does work better with the neck and middle. |

Although, I think it does work better with the neck and middle. Wow this is so cool to hear! I’m in luck, I want my out of phase blend for the neck and middle position as well! And the middle and bridge too if possible. I made a thread about this recently, something like “positions 2 and 4 on a Strat with out of phase blend” or something like that. What I’d like is, when the phase changer blend knob is at 10, you got them (neck and middle) positions basically in phase and of course in parallel, like normal and quacky. Then as you roll off the knob, then out of phase ness starts to add in gradually. Hopefully down the knob there will be that octave stuff you were talking about it. I was thinking of getting the middle pickup out of phase gradually, but in my thread, thanks to the help I got there, I realize this cannot be done, well not in the way I want. Now I’m thinking of doing the Dan Armstrong blend mod but just the 2 and 4 positions of the mod. As I turn the knob, the bridge pickup blends in out of phase in position 4, and neck pickup blends in out of phase in position 2. How did you do the out of phase blend, gckelloch? Thanks! |
