New Pedal Day- MXR Classic OD

Re: New Pedal Day- MXR Classic OD

I'm going out of town next week, to a place with a GC. Mioght have to pick one of these up just to the hell of it.

If there are any left.
 
Re: New Pedal Day- MXR Classic OD

Thanks! That is very helpful, much easier than the latest push/pull wiring I did. I'm definitely going to do this. My only concern is where to put the actual switch. I've seen them in a few different places, I don't want to worry about the switch pressing up against the board. I'm thinking top right hand or left hand corners? I like your position in the middle there, but was it hard to fit it there?


The prongs on the switch I got made it hard to find a good spot (too long). I even thought about moving the yellow "diode" near the switch so I could accomodate the switch there. De-soldering the switch was hard enough as it was so I looked for another spot.

B.t.w. I'm a carpenter/joiner, not an electromagician.

The best spot, IMO, is right where the PCB switch was located, or close to it in that upper left area. You can real estate by removing the stock switch anyway.

I'm going with top left. Now I just have to figure out how to actually wire. I'm kind of a colors and pictures guy, I don't actually know anything about electronics. If I had those same wires on the board (two reds on the ends, one black in the middle) which lugs on the mini switch do I attach them to? Here is me taking my best guess:

You need a switch with just 3 prongs (it has to be an "on/on" switch).
I used 2 different color wires, because that is what I got. Easier to explain would have been if I used 3 colors.
But it is quite simple. Just lay down the switch and connect left to left, middle to middle and right to right (parallel).

Another practical question. How does the original switch come off of the board? Just yank it with some pliers? I really need everything spelled out for me, this is not my main area of expertise.

Tried yanking it, but had to de-solder anyway. This was actually the hardest part. The solder on the bottom of the PCB came off quite easy. But there is a bit of solder on the component side of the PCB as well, which is hard to get to with the switch still on.

Cool, sounds like I know what I need to know to get this done. I'm going to order a mini switch now. Any recommendations? I can get a dimarzio one from musicians friend for $7.99. Or that guitar fetish one for about the same price when you include shipping:

What you really want is a switch with the shortest prongs as possible. I bought mine at a shop like RS (but we don't have RS in The Netherlands)




P.S. it would be cool if someone posted a pic of the PCB from the "Classic".
I have a feeling they combined the "MXR '78 badass" with the "Classic" and they combined the "GT-OD" with the "ZW 44" on their respective PCB's

Very good thought. Anyone know if this is true or not?
 
Re: New Pedal Day- MXR Classic OD

Can't wait to find out! That would be sweet to have a bonus distortion pedal, but I'm pretty sure I've seen Classic owners say that their switch goes to the ZW.

I think he is talking about the Classic Distortion. The '78 is so new I doubt the circuit was built into the CD, they've been out for a while. Might be able to get there with some component changes(?).
 
Re: New Pedal Day- MXR Classic OD

I think it's been established that the classic distortion is the distortion III, and I don't think there's a switch.

Yup, just opened my new Classic Distortion up. No switch, but that's not what I was looking for -- pulled C4, and instantly made it a better, brighter pedal. YMMV, of course.
 
Re: New Pedal Day- MXR Classic OD

Well, I pulled the trigger on the M-66, white with green lettering. Went up to GC an hour ago. They (in Sacramento) have 5 more in stock. They don't have any more green CL-1 models and won't be getting anymore in. At least not at the $29.99 price. Darn! I was going to get one of them and do a "taste test" compairing the ZW-44 I have (no switch) anf the M-66 and Cl-1.

Oh well, at least I've got one of the anniversary editions in white with green script.
 
Re: New Pedal Day- MXR Classic OD

Update: I did the mod today. Took me 20 minutes! It was a little too easy. The switch is really crammed in there but it is in and working fine.

Now, help me figure this out. So I lined up the wires in parallel and the switch has not been twisted around, it is still in parallel position. However, when I flip to the left, that actually sounds more like the GT-OD. To the right, ZW. Isn't this the opposite of how it should be? The stock switch on the board was in the right position. Now, when I move my mini switch to the right, shouldn't that be the same setting? When I switch from right to left there is a thumping addition of bass to the tone and possibly more volume as well. Let me know what you think.

Thanks to everyone who gave me info and guidance on this mod!
