Tascam Model 12 Knobs

[tangucho]

Hello all,

Is there any guide on how to remove Tascam Model 12? Are those of any special size or specs?

My intention is to replace the stock knobs with some dark-glowing knobs. I want to be sure I get the proper ones...

Thank you

@tangucho welcome to the forum! Don't know of any guide for removing the knobs, they are likely the common D-shaft type. IMO you should be able to remove them easily by pulling with your fingers, if the knobs are too tight try gently prying from the bottom using two plastic levers positioned at the opposite sides of the knob. Just what is needed for pulling any average knob on any average mixer (just to speak).

@Max Relic thank you! But it happens that I am not able to easily pull them off no with fingers or using a plastic card to lever it.

Actually I am quite intrigued. I even tried to remove the color part but that does not work either.



Indeed it seems that they are common D-shaft type as I've found the item here:

I bought these as I need more color for dark venues:

I know it is a dumb question but

1) Pulling them off does not work
2) Use a plastic card to lever them does not work either.

You could just paint them with glow paint.

Why did you buy the new knobs without verifying the pot position relative to the shaft orientation on the Model 12? If you get the knobs off and the orientation is wrong, what then?

@tangucho I know Chroma Caps are popular among DJ and live performers and understand your urgency to upgrade your Model knobs, but logic suggests you should:
1 - take off at least one knob to identify the exact type
2 - order the right replacement parts

Anyway, I confirm the Model knobs are *tight* so you better find those hard plastic levers used in pc/phone repair*. Don't know if a common guitar knob puller could do with the thin ones in the Model.
@-mjk- If the replacement knobs are the wrong type our friend @tangucho will return them and ask for the right parts, hopefully learning something in the process.

*= Put a protection layer between the Model surface and levers in order not to scratch the graphics. Unless you plan to do a relic treatment, of course.

Thank you both @-mjk- and @Max Relic , I confirmed with some pictures that parts with 270 degrees as offered in DJ Tech Tools would fit. Just to let you know that they have a policy of full refund if the knobs does not fit the equipment (if the gear is not listed in their compatibility list - which is the case).

At least there is that. But shipping returns is always a drag.

Were you ever able to figure out a way to remove the knobs on the Model 12? I would like to remove them and replace with some nicer analog synth type knobs. I can't seem to pull them off either.

Does the knob have a white cap that comes off? If so, there may be a collet underneath that needs to be loosened in order to take the knob off?

I have tried using a tiny flat head screwdriver to remove any type of cap, with no luck. The Model 12 has many colored caps tops. there has to be a way to remove them for repairs. Has anyone taken one of these apart?

 

[tangucho]

No luck so far. I have the replacement knobs stored waiting for a way to remove the old ones...

Unfortunately, I tried everything with no success. I design and build midi controllers, so have had my fair share of taking apart and rebuilding synths, mixers, sound boards, and other equipment, and in 40 years tinkering with electronics, I have never seen anything like this. Anything that is built should be able to be taken apart. So I gave up on replacing the knobs on this a while ago. I even reached out to Tascam but didn't get anything back from them.

 

[tangucho]

Well, I am surprised (am probably you will be also) that it seems that it is not that hard....

Check this out...

(I already contacte the youtube user that posted the video asking for directions). Let me know if the video itself give you any hint.

Thank you for this. It appears there are three clip slots. Maybe he just used a pair of pliers to remove them? I noticed he replied and mentioned the he had a broken one that he damaged. I'm not willing to go that far for aesthetics.

EDIT: I just read his comment again, and he damaged TWO units attempting to remove them.
