Please take some pics of the Hall effect sensor & how yours is mounted.
I have been trying to compare the resting position of the sensor, over a few internal pics that I have.
If you recall? Mine (wah) seems to have very little usable sweep, no matter how I set the controls.
it seems that from inspection the other pics, my Hall effect sensor was factory fitted a little too high, & does not see the the full range of the mechanical sweep of the treadle.
I've put some pictures of the PD-1 in the internals thread but here's the one of the hall elment again.
It looks like it's mounted very much as described in the schematic:
When I tested my PD-1, I couldn't actually flip the switch mechanically. I assume that there used to be some sort of rubber pad or sponge, glued to the underside of the pedal, that would touch the switch. It had disappeared so I had to improvise. I super-glued a bit of rubber to the underside of the treadle and cut it with a knife until I thought it was low (or high) enough. A picture explains better what I mean.
I had to do this for both switches and the thickness will determine how much sweep I got before the switch activates. How did this look originally? Anyone know? |

I never really noticed that before, about the mounting of the hall sensor, and I'm the one who sent you the schems
My sensor is about a 1/16 below flush, and I thought it was too high
Mine is also missing the rubber the switch, and the back bumper looks like it was hacked at to allow the switch to be activated. |

I just bought my pd-1 and I've noticed that the sweep does not control the amount of distortion very much, except the boost in warp mode.
Is this normal for this pedal? If not, any suggestions how to fix it?
Anybody know here can I find manual and schematics for this pedal? |

Hi pefo5543
Welcome to the forum from Australia.
Not 100% sure, but Christo might have the Sch, for the PD-1.
Any chance you can take some internal & under pedal pics of your PD-1?
It would be greatly appreciated, as there is little information & pics of these, to compare with.
The sensor area & the switch/pad area.
My Hall effect PCB (Was) mounted too high, & that was from the factory.
Regards Dr. Bob  |

Hey pefo, welcome to the forum
pm me and I'll send you the service notes for the PD1
would be cool if you could get it going agaon, its got a unique distortion
never noticed the two clipping diodes on the low end of the Tone pot |

Thanks, sorry for the delay, my camera screwed up.
I also have some problems with noise, after tweaking the internal pots it's better. In warp mode theres still some noise though.
The hallmount looks ok to me:
Maybe I will put some rubber underneath like you did.

Hi pefo5543
Great internal pictures.
When uploading pics to the forum, please use a graphics tool to (not crop), but re-size them to around 100K to 250K.
It reduces the chance that the Server will TIME-OUT, because of their upload size.
Plus it makes them a lot easier to view them on the forum.
Perhaps you would consider uploading these into out Pedal Internal thread?
I will then add them & you, to the Index Page
Regards & thanks again Dr. Bob |

Hi everyone. My first post here, have gone through a lot of boss pedals when I was a teenager but just recently I grew nostalgic and started to collect these pedals I recall from the 80s. Then I discovered this forum 
After many months of searching I finally got hold of the PD-1 rocker distortion, unfortunately it is only half working, kind of...The effect turns on and I do get sound but rocking the treadle doesn't change the distortion amount as I supposed it should. I opened it up and the interior looks exactly like the pictures posted here. The hall element seems to be mounted correctly as well, so I'm thinking maybe it is that part has gone bad over the years. Has anyone run into this problem? Or has anyone tried replacing the Hall element?
Oh, and any chance of finding the schematic? Thanks so much already  |

Hi prological
Welcome to the forum from Australia.
As far as I remember,
no-one here has any of the Schematics for the Rocker series.
Regards Dr. Bob |

| Thanks for your help guys. I'll let you know if I can fix the problems. In the meantime feel free to share your PD-1 issues cause the Hall element isn't the only thing wrong with mine! |

Anybody got any idea how to make this PSA compatible?
Normally you would just jumper the res/cap combo, but the PD1 has a transistor connected to the middle. |

Aha, great question Christo! And I was wondering why mine wasn't working with the adapter 
I think another useful mod would be to make it work with a regular 9v battery. Has anyone done this or do you guys go out and buy 1.5v batteries just for this pedal? |
