I got that lovley little PH-2. it sounds warm to my ears so it must be analogue right? If I opened it up I wouldn't really know from looking if it was either mind. It's a thick phaser sound to my ears, I'm using it on synthesizers though. anyone know?.... thanks |

Tried opening mine the other night, but one of the screws wouldn't budge :\
So sorry, I can't help, lol. But I presume it's analogue. It's a basic enough pedal and I can't see that they'd need to make it digital. Correct me if i'm wrong though. |

heh, just tried to open mine, yes! needed a cool drink after that!! those screws were damn tight, had to put the ph-2 in a vice, very gently holding it whilst is put a rag over the screw handle, I think it hadn't been opened before.. anyway after that opened it up. the back of the circuit board is green with lots of metal blobs and lines, the bumpy side is coloured brown, lots of chunky sticky up things. only 2 small microchips, no main big one... Yep! it's defently analogue! Those chips are probably somthing to do with the switch between mode I/II.
I guess if it were digital you'd have a big chip in the center with a million pins and not much else.
So I don't want to see any more lame people complaning the sound is digital and thin! It's fatter than that PH-1 to my ears anyway. |

Not necessarily. When I opened up the CE-5 (see CE-5 thread) I excpected it to be analog because there weren't any large chips like in the DD-3. I had to search google to find out what the chips actually contained before I could make a conclusion (which may still be wrong).
The ICs in the PH-2 are however more likely opamps but to be sure, write down their numbers and look them up on the Internet. |

thanks for the replies, I don't even know why I'm asking, of course it's analogue it's a pedal from 1994 and was probably released 1995. The board is def analogue and the sound is fat. So there you are i've decided for you!!
as for the VERY EXTREMLY small chip, didn't see any number, just said 'roland' on it.
Well, I'm glad it turned out to be analogue! |

If the circuits say "Roland" on them, you could be looking at a digital circuit. Most analog chips (delay chips used for phaser/flanger/chorus type effects) were sourced from outside manufacturers, while many of the digital circuits was/are made specifically for Roland/Boss.
Still, even if the actual delay circuit that creates the phasing were to be digital, 90% of the audio path will most likely still be analog. It's only the most recent Boss pedals (PH-3, DD-6, AW-3 and others) that are more or less 100% digital. But do post the numbers, if you can - that will usually clear everything up quite quickly.

FOUND THEM! 
OK I'm guessing this is the 1984 model, there was no re-issue I don't think. it's the Taiwan silver lable
numbers:
IR3109 Roland 793D
IR3109 Roland 794D
argh! stupid screwing time heh

The IR3109 is a voltage controlled filter (VCF). it is heavily used in most of Roland's analog synths. Nothing digital in there  |

"Nothing digital in there "
yep! all analogue. you know why people say the PH-1/PH-1R is more analogue, it's their own fault they are being fooled by the oldskool chunky knobs, interface has nothing to do with it. I have a roland juno2 synth and the interface is very digital looking (1 second look of it makes you think mega-weak sounds) but in actual fact it's all analogue!
so don't judge a book by it's cover.
It made me laugh reading those Chorus Ensemble reviews on harmoney central, everyone was saying it was digital. then FINALLY some one opened it up and basically told them the facts that the circuit was analgue...
but yeah, decieving interface and doesn't have the oldschool chunky silver cap knobs. It's a trick of the mind. |
