Hi
I have just bought a DM-2 but it seems to be a very late version. The 3 knobs are all small and have a red line as the marker line. The labsl is blue with an extra line added at the end for FCC compliance. The PCB is ET5214-510B 2291045804 and the chip is an MN3205.
I have not seen any other like it. Is it very rare (and valuable?).
Thanks
Steve

It sounds like the knobs have been replaced. All DM-2s I've seen has had the standard knobs used on all 3 knob pedals (except CE-3). I don't know the exact difference between the ET5214-510A and ET5214-510B version but they both use the 3205BBD so they're probably very similar.

There was an earlier version too - ET5214-510. The difference between this one and the A version was a diode connected to pin 1 of the clock driver was moved to the ground terminal. Don't know what it's for but if anyone can enlighten me, please do.

Oh man! Now I have to open up my DM2s and see which versions I have!

But wait... Who wants to freak out over OD1 versions? Anyone?

Just make sure you don't touch any of the trimpots when you open them up and you should be ok. Maybe hide all the small screwdrivers first to make sure you're not tempted

Hi
I have emailed 'bossarea' with pictures of my DM-2 for his opinion (hope they are not too big). I bought it from a lady who had no idea what it was, in a car boot sale, for �1!!
I was going to eBay it, but it sounds so good I am going to keep it (I have a ToneLab SE too).
If anyone else wants pictures let me know.
cheers
Steve

To get oscillations,
turn amp to barely audible first!

Repeat Rate = 80% (3 o'clock) approx - may need small adjustment
Echo = 100%
Intensity = 100%

now hit a string (may not be necessary).
Adjust repeat rate slowly once the 'warbles' start to build up.

Sounds like the film 'Forbidden Planet' - 'Monster of the ID' to me!
cheers

�1!!! That's amazing. On the boot sales around here (Reading) there's only old lamps and dishes with "Gran Canaria" printed on them

Here's the pics:




The knobs don't look original. They look like the black ones used on the VB-2, BF-2 and CE-3 but the red line doesn't make sense. I'm quite sure they're not original.

I've never seen another blue label DM-2. All I've seen so far have had a black made in Japan label. My speculations have led me to believe that the first blue label pedals came 1985 - a year after they stopped making the DM-2. I suspect the bottom plate may have been replaced too but I could be wrong.

Okay, check this out.

I got my first DM2 a couple of years ago. It came with a silver screw and the accompanying bottom plate ("Use a coin..."). It has the paper label serial number inside the battery compartment. I thought after reading some information on the web (including bossarea.com) and in the Boss Book that there must have been a replacement made on both the screw and the plate in order to pass of the pedal as a "silver screw" model by the seller.

I just got another DM2 in the mail today. It also has a silver (well it used to be silver... it's a bit tarnished) screw and the accompanying bottom plate, which wasn't even listed in the seller's information. It also has the paper label serial number inside the battery compartment.

Weird thing is that I've never seen any other examples of this on a DM2.

Anyone else had this version of the DM2?

bossfreak, what are the serial numbers on the two pedals?

my DM-2 is a black label but get this, it says "use a coin to open battery compartment" yet it has a black screw. the serial number is 094000, on paper. from an earlier DM-2 topic, i opened the pedal and found it to be the early PCB.

i also think the knobs on the that other DM-2 are not original and here's why: even if they are genuine boss knobs, they were designed for pedals that did not use the traditional V formation of 3 knobs; they were smaller so that 4 could be mounted in a row. of course the ce-3 only had 3 fitted in a row but they were never fitted to a V formation pedal.

I'll have to get back to you on the serial numbers. It seems odd to me though that I would end up with two DM2s with silver screws. The one I acquired most recently, as I mentioned above, had no indication in the seller's description at all that the screw was the 'silver screw", which leads me to believe that it's not a matter of a "faked" silver screw pedal. Additionally, the price was much lower than the average price for a DM2, which is why I bought it, even though I didn't need one for my rig or my collection.

With two identical pedals I'm thinking they're both original.
My own DM-2 has the black screw and a bottom label that states "unscrew using your fingers...". The serial number is 232300.
