Only the CE2 has the 3007 chip, and later the 3207
the TR2 uses a M5218 chip, not sure, it don't think they're BBD chips |

Hi onerevolution, welcome to the forum from The City if Brotherly Love! I havn't seen that one yet, at least not in my Ibanez pedals. If you post this in tech. Mod catagory, Laurie or Dr. Bob may be familliar with it. |

thanks for the responses. i could only find reference to the chorus pedal with that chip. but i have seen some mention with the new malekko vibrato pedal (that uses that chip) and the older boss tr-2, but maybe it was just a typo, and they meant the chorus instead.
i will try to post to that other section as well. |

I think this is a (almost) complete list of which BBD is used on the different analog pedals.
I suspect the BF-2B has the same BBD as the BF-2 but would have to take it apart to verify it.
BF-2 -- MN3207 ........... 1024 stage
BF-2B - MN3204 ............ 512 stage
CE-2 -- MN3007, MN3207 ... 1024 stage
CE-2B - MN3007 ........... 1024 stage
CE-3 -- MN3207 ........... 1024 stage
CE-5 -- MN3007 ........... 1024 stage
CH-1 -- MN3007 ........... 1024 stage
DM-2 -- MN3005, MN3205 ... 4096 stage
DM-3 -- MN3205 ........... 4096 stage
HF-2 -- MN3204 ............ 512 stage
VB-2 -- MN3207 ........... 1024 stage
Edit: added information from ChristoMephisto's post below. |

The BF-2B has the same BBD chip as the HF2, the MN3204 a 512 stage driver. The 3007/3207 were 1024 stage drivers.
And just to cover all the bases, the MN3205 were 4096 stage Low Voltage Operation Low Noise BBD ( 4096) |

| Out of interest, do we actually have a record of the switchover on the CE-2 from 3007 to 3207? The only schematic I've seen shows the 3007. My MIT has a 3007. Changing the IC from one to the other requires rewiring the supply rails and altering the PCB, so I'd expect changes to the service notes. |

| The CE5 Chorus Ensemble has two service notes around on the net, for the CE-5 and CE-5A, whats not to say a second edition of the CE2 never went public? |

| Not saying it didn't, just that I've never seen it. I'd be interested to know when it happened. |

I've never actually seen any CE-2s with 3207 BBDs but it has been reported on the forum more than once. If the change is more than a drop-in replacement, I find it hard to believe that Boss would go to the trouble of redesigning the pedal just before end of production.
Nathan, when was your MIT CE-2 made? The last CE-2 I've seen is CC98667 (Aug-91). |

| No serial I'm afraid... I've got some pics I can post of the board if that helps date it. I'll dig them up later. |

Hi Guys
Are there any members that actually have a CE-2 with MN3207 BBD's?
I was so keen to investigate this fact that;
Yesterday I specifically looked at the few CE-2's that I have here.
All of my CE-2's have the MN3007's
Even the two MIT CE-2's.
I also looked at my repair records & history,
for any CE-2's that have been sent to my Lab.
And all of those had MN3007's as well.
Regards Dr. Bob  |

OK - here are some pics of my MIT CE-2. The serial is missing, but perhaps it can be dated by other means.
