Back when I heard that the 417 was Dumbles favorite speaker I picked up 4 from a friend..Got a pretty good deal on them and they were in great shape.. I've tried them in several ODS style builds and just never took a liking to them.. The Alum dust cap emits this annoying buzz beam..I've tried tweaking here and there and on the recordings it's not as apparent.. For the clean side was pretty nice but the OD Whew!!.. Ebay here they come..

I have played several of these and they are in a different tonal league when you compare it to BF fender trem circuits. I took a quick glance at the circuit and it "appears" to use phase shift to induce the effect and not hard amplitude changes.
Implements right before the power amp, so it could be adapted with a little ingenuity. Could probably also be built as an external item and placed in the loop.

couldnt agree more Gary.., i built this into a Matchless chassis last year for a pro player in NY ( Marcus Wolfe) with a Dumble meetst BF preamp, needless to say it SWAMPED HIM!!
Re: Fender 6G4 Super tremolo - I looked at this one - the tremolo takes 2 tubes to implement and appears to do some major tone and volume sucking. A dead give away is the use of a 1M as a mix resistor for the second (non-Tremolo) channel.

And Fender laughed all the way to the bank....maybe i`l try yours next time! Thanks for posting!
It's kinda weird when this amp, supposedly having been modified in 1979, is listed in the auction as a predecessor to the Overdrive Special which had already been out for quite some time in 1979.
This is my first and probably only post to this forum.
After reading for awhile and following this particular post, I feel I have to add my two cents worth.
First of all, at one time I owned two different Dumbles, and have played through many other Dumble amps including the amp in question, the 'Overdrive Deluxe', in New York around 1996 or so.
I have to tell you, it is still etched in my mind as one of the best amps I have ever heard.
It was owned by a guy from the mid west if I remember right who was playing in the area.
The You Tube clip does alot to convince you that this is a pretty special amp, but in person, it was amazing.
It seems like Hotrod Ford has an agenda;
why are you so vehemently against this guy trying to sell an amp?
After some digging I found out some interesting info; with all due respect I ask you this;
Are you the same person that does ODS clones in Europe under the 'customs by cougar' name?
If so, then where do you get off saying that this amp is a fake?
How could you possibly know that? Have you played it? Have you looked inside it? Were you there when it was built?
Or do you want to discredit it so you can sell your own fakes?
And before your post, everyone was touting the amp, saying how great it sounded and wanting to know how HAD did the trem.
Now you're all on the band wagon to piss on it and believe its not real.
When did you develop the hive metality?
That is a little extreme and hypocritical.
Because lets face it folks, everyone on this forum is stealing H.A. Dumble's designs.
It is great that there are so many people making great amps these days.
We all know the horror stories and conjecture about Dumble.
He is the Howard Hughs of the amp world.
That being what it may, there is no possible way of knowing that he did not build the Overdrive Deluxe on ebay.
After listening to the sound clip, to me, it should convince most people that it is almost certainly a Dumble creation.
So before you post and join the angry mob, keep an open mind and try to respect the rights of everyone.
I wish I could afford it, I would certainly buy it.
