For those of you who are interested, i own a dumble overdrive special combo , serial number 99 in orange-rust suede, 100 watt in mint condition, black chassis with script logo. The 12" speaker is a very rare, EVM-12S. After Gene at Ultrasound in NYC inspected the amp's internals, he described its condition as N.O.S.

Hi Herman, it would be interesting to see a photo of your 99, cheers, Gregor

Hi Gregor, my dumble ODS combo is pictured in the post immediately preceding your post of july 6, 2008. It was purchased in the U.S. As I indicated in my last post, who ever purchased my ODS, rarely used it !!By the way, i have always admired your guitar-playing skills and tone. Best of luck with your EBAY auction !!

However, the plate load and cathode resistor and the cathode bypass caps look too modern to agree with the rest of the amp...

Gil

Why do you say so? I can't remember correctly but that kind of resistor was already common in 1983, and they seem to come out from under the original black gooping too.

The whole amp seems original to me, never upgraded, only degooped.

Let's wait and see, if the collectors think that a degooped ODS is still "original" or not. At the end of the auction we will know, if collectors pay 50 for a degooped ODS.

Well, I meant never upgraded by HAD. Upgraded by HAD it may become even more valuable. Anyway I'll wait and see.

You may never know what this sells for boys. I don't think eBay is the only place this amp would be sold through. He can sell it privately and pull the auction at anytime canceling all bids.

Hi Gregor,

Yes you can definitely get additional info from the board.

EITHER, If you own a multimeter, you could measure the resistor values and also have a look at the orange capacitors. And just write the values on the photos, you allready posted.
OR, take some very close pictures of the amp inside- I suggest ten closeup pictures from the amp inside.

Then, members of the board, will be happy to ell you accurately which schematic / diagram fits the amp and you could print the schematic and give it to the new happy amp owner, as a nice gesture.

All you have to do is spend another 5 minutes with your digi camera

PS: I bought a couple of SD Antiques humbuckers from you last year, which have found a happy home in my ol' Les Paul - so I'm one of the guys who gave you a positive rating on Ebay

Hi, maybe I could photograph everything again. But this needs more than 5 min. I have to see wehen I have time to do that. Cheers, Gregor

Greg, befeore you get to sell the amp, you would make a lot of us pretty exited if you could take a few detailed gut pictures. I urge you to please take some time to do so. You know one small step for Greg man, one giat leap for the rest of us.......

Teo,

What I think is that the resistors look like the KOA Speer (or whatever) that Dumble used in the early 90s amps, and the cathode bypass caps also look modern (judging by their size). The good, on the other hand, does look original. Love the way that ams sounds!

Gil

One of my amps is very similar to this one and it sounds very good, but with my pc and earplugs I can only hear a too thin sound from the Gregor recordings I tried. I am sure the amp actually delivers a full bodied sound.

Do you know if they are "metal film" like the Dale's?

They are metal film but not 'Mil Spec.'. The current production 'standard issue' Xicon and KOA metal films are blue and banded, like those.

In terms of resistor wattage in #94 (and other 'blue resistor' amps), maybe Gil knows if they are 1/2 or 1W, but the current KOA 1W Metal Film resistors are pretty limited in range of values (or at least those carried by Mouser).

I doubt that de-gooping hurts the value at all, but if need-be the goop is easily put back.

[tonelab2]

I should have known better. On my 70s clone I tucked the relay board under the treble,mid,rock/jazz switches.

[ic-racer]

Of course, right where is should be! Good work!
