Thanks neskor! Lots of good photos there.

Thanks neskor! Lots of good photos there.

These gut shots are gold dust, whats the giant cap around the back of the chassis?

That is the V1 plate supply filter. You can see that on the Second gen layout drawing.

Looks almost new, doesn't it?

Man thats so much neater than the way I did it hanging off V1

it shows that Dumble was constantly evolving the design the way he wanted. Supurb!

ill check the 2nd gen layout out

The red Stackpole switches look pretty cool—at least, I think so.

This was my initial reaction too. I was going to take a peak in the Dumble book to see if this amp is there. Everything is so clean and solder joints so shiny. It looks legit but made me wonder at first if this might be an excellent fake.

As far as I know, for various electrical engineering reasons, it is generally recommended to keep the interior of a guitar amplifier as clean as possible—for instance, by regularly removing dust and the like. And when looking at such photos, one should perhaps bear in mind that lighting plays a crucial role in how shiny or matte metal appears in the image.

Fair points Max. And good on the seller to clean thoroughly when asking such a high price. Most amps of this vintage I have seen are maintained less diligently.

Dan, I assume that the price asked for the OD-50WX #0023 (with the PI-D12) might be based on the price of a similar combination—the OD-50WX #0041, also with a PI-D12—that was sold a few months ago: https://reverb.com/item/96548480-dumble ... gray-suede. This is despite the fact that, in my personal opinion, the OD-50WX #0041 makes a slightly less well-kept impression overall than the OD-50WX #0023. But, of course, that is certainly a matter of opinion.

I’ve quickly dug up two photos of two amps which, in my opinion, give a similar impression regarding the overall cleanliness and the shine of some of the solder joints as some of the pictures of OD-50WX #0023. But perhaps that's just my personal impression. Here they are:

Max,

Thanks for the pictures. Would you mind letting me know what serial number the top picture is? I don't remember seeing that many Alan Bradley resistors in Dumble amps. I'm sure it is common and I just haven't seen the pictures.

Thanks,

Mike

It's Overdrive Reverb Special #0015. If you are interested, you can find some comments here https://www.instagram.com/p/DCjNOPROGIw/ on some of the components used in it. And you’re right—you’ll hardly ever find two Dumble amplifiers where he used the exact same components in every spot, even with very similar circuit designs. That’s why taking a look inside one of his amps—especially one you haven’t seen before—usually holds a small, or sometimes even a major, surprise. In my opinion, this also applies in certain respects to the OD-50WX #0023 discussed here. Here is yet another picture of the ODRS #0015 on its matching PI-Q10 cabinet: https://www.instagram.com/p/DCjHNyMOguZ/

Thanks Max for that info. I had seen that website before but I had no idea what serial # it was. I must say, your picture is a lot more detailed than the one on Instagram.

Thanks so much. I continue to learn

Thanks Max. Do you have the serial number of the second one? I have only seen a few ODS pictures with "modular" PCB construction. Seems like HAD was trying to reduce assembly time with that approach.
