Re: Dumble Clone Parts: Trannies etc...
So far it sounds like Twin style trannies (or Maybe that new sensor MPT-100), 12" EV speaker, and no reverb are the way to go.  
Graydon Stuckley is building the chassis for me. I want the tubes on top, English style, (less heat destuction)and an extra preamp tube. (I want to install the dumulator internally)  
 
So I need a 4 ohm 12" EV or get an OT with an 8 ohm tap (like the magic parts one)  
 
I have been doing some experimenting with very satisfying results. I built a tube distortion pedal(similar to the matchless hot box)  
with three 12ax7's. I put a regulated power supply in it and the Dumble circuit. For the OD section I tried the skyliner, a bandaxall tone stack, even a tweed deluxe type tone stack. Finally I tried the old style OD section(with .0035 across the last plate resistor to keep from ripping my ears out) and wow! Playing thru my EV equiped princton reverb, I'm sounding like Robben (if I could only play like him!). The skyliner EQ does give you a Marshally vibe, but the original OD circuit really sings! I've never such a vocal tone before. I can't wait to hear it in the entire circuit. However I really happy with my little dumb-pedal. I've modified this thing for five years (even had a SLO 100 circuit in there)and I'm finally satisfied with th it.Can't wait to play live with it!  
 
Thanks for the insightful comments, if anyone has an EV they want to sell or trade let me know.

Dave:  
 
    Can you spell out the details of your "dumb-pedal"? Like the PS voltages and resistors, the plate and cathode resistors (and bypass caps), pots and trimmers you used, tone stack details. Here is a survey form (less the power amp section):

Dumbleator and "Send in the Clones!"
Dave: if I were you, I would build the Dumbleator separately. Keep the amp simple.. otherwise you will have to modify the power supply to get the right voltages there. The extra cost would be about $30 for a 1-space rack chassis, but overall, you'd be better off....  
 
Stevie: "Send in the clones.." you crack me up! :)

any chance there are any Steve Taylor fans on the BBS?  
 
he "sent in the clones" almost 20 years ago.

I'd gone through so much other stuff  
that walking down the aile was tough  
but now I know it's not enough!  
 
Steve who?!? Isn't he James' brother? ;-)  
 
Has he done anything since "I Predict.." except for a couple of guest appearances on TBN?

Steve has been into production lately; one of my favorite albums is the Newsboys' "Take me to your leader". I was intrigued by the fantastic lyrics until I read the credits- Steve Taylor co-wrote nearly all the songs and produced it also! Check it out if you haven't yet.

Steve Taylor Stuff
Steve Taylor is VERY VERY busy. He fronted Chagall Gueverra in 1991 or so. A great album that failed commercially was the result, but before long his most recent solo album "Squint" was released. A tour and live album followed. The album had incredible modern rock tunes with quirky and poingant Steve Taylor lyrics. He is now the man behind Squint Records. Squint is the label for Sixpence None the Richer and several other recent bands that have been popular on MTV, VH1, Dawson's Creek and movies. Speaking of which, last I talked to Steve, he's working on a movie.  
 
Rant is now over.  
Any questions- drop me an e-mail!!  
 
Taylor Fans unite!!!!
