eBay listing: 7349301458
Does anyone know anything about these? Obviously not the everyday Compact Pedal... |

| Interesting pedal, as i posted elsewhere here, peoiple either love it or hate it. it has the famous JRC4558 chip, along with another chip; the TC4011 used in the sought-after flangers, phasers and chorus pedals from the 1970's and 80's (this info about the 4011 i got from another post not direct from schematics so don't hold me to it if i've been misinformed). The switch to turn the effect on and off is located under the near side of the rocker (!?!) which is counterintuitive to those of us who are used to the traditional wah pedal setup. the chip provides a great range of distortion if you open the pedal up and adjust the trim pots inside, many people who really dislike its sound at first change their tune after adjusting these pots. I've been looking for someone to come up with a good mod for this one (maybe switch the on/off switch and add an external knob or two to adjust the internal dist parameters), it certainly has potential and can be found for a steal as few people know about it. |

| I've Tested out the wah version and it sounded ok, not great , but ok. And the price wasn't too bad either ($45.00). |

The price is one of the things that make these pedals really attractive. Build quality is another. In true Boss tradition they're built to withstand everything you throw at them.
Sound Quality? I have no idea. I've never tried one. |

I used to think it was one of the modern virtual Wah's as it has that look, or did I just  a little too much?
Well another one I would like to listen to. |

| I have one. What's cool is that if you push down hard with your toe there's a gain/volume boost that's good for feeding back. |

i picked up one of these recently from musictoyz.com & it's way better than the ds-1 (taiwan). much fuller sounding. the only thing bad is i had to get a separate power supply (aca).
what pedal board power supply do you think will work with this?
oh yeah, it also came in the original box w/ 2 old boss stickers & a pouch. |

The Pedal Power from Voodoo Lab can supply the proper voltage for the old ACA pedals (which want to have approx. 12v DC), or you can use any multiple output power supply as long as you have at least one other PSA type pedal or any newer pedal that is designed to run on a regulated 9 or 9.6V supply connected into your pedal chain with the older pedal(s). There is another thread here that explains this in more detail. I use a Boss RPW-7 normally, but I've got other supplies that work as well.
Let me know if you need help finding the info.
Grace and peace,
Steve

the pd-1 works great for bass. i'm getting rid of my odb-3. the pd actually distorts the bass whereas the odb sounds like the dry signal playing along with noise. the odb sounds separated which defeats the purpose of distorted bass.

I just got a PD-1. Bought something like 40� on ebay.
Well, it's good to see it besides my FW-3. Those are great pedals, really, really huge but could bear a nuclear war without suffering...
It's a MIJ black label, and a silver screw model ! 
It seems to me, at first, that it sound something like a DS-1. But with the possibility to have very little gain. I'll tell you more about when I test it further...
Inside, it's Boss classical. Clean. Cardboard insulation sheet. 2 trimpots which control some gain, but how... ?
Where the standard footswitch is usually located, there is a "warp" switch, which seems to introduce really more gain. I'll have to pic up the schematic to make all this clear...

I just advanced the schematic. It seems quite curious.
First, the power supply is way more complicated than usually. Power supply and signal grounds are separated, using a PNP transistor, and some sort of boosting circuit. I don't know how this would behave if plugged with a daisy chain. I'll test.
Secondly the pedal acts with a magnet. A magnet sensitive device is settled in the box, and the pedal moves a magnet towards it. Strange thing, I must say. But it works fine. Interesting. The variation is controlled with an opamp, and transmitted to the gain stage with a 2SK30 JFET. The two trimpots control some parameters concerning this transmission, but I did'nt took the time yet to look at this further.
There is a 4011, which is a quad NAND gate. Surely used to control the many JFETs, but I didn't picked up this part so far. Dylan, I don't thing this could be, at all, a sought after part. It's only a logic gate, not an opamp. And surely not used in the signal path. I can be wrong, mauybe some guys are nuts at this point, but for me a logic gate is a logic gate.
There are 2 "soft clipping" diodes, AND 2 "hard clipping" diodes. Waoh... The gain stage is around a single opamp.
The Warp switch just introduces more gain, as far as I understood how it works.
Tone is a simple RC net, just identical to a tonality pot on a guitar. Poor, I must say. But well... |
