||Re: Old Styl Dumple OD: ears ringin!|
I think if one follows the lead dress of those amps carefully (that is, from left to right, and not building them inside a Fender chassis where the signal has to be routed back and forth a few times to use the existing holes for the pots on the front, the amp will not be unstable at all.
Check your grounding scheme, including the filament harness. That would be the only cause for hum, barring bad tubes of course.
Yes... Remember the Guitar Player Dumble review, where they said the amp was stiff and somewhat harsh? I have consistently been told that Dumble voices his amps very bright "from the factory."
If you're referring to the amp that uses the extra TS, sure, you can make it sound like anything you want.
You mean at the post overdrive tone stack? It would seem to me you can make that as honky sounding as you want?
You mean gain or volume? If volume, it would be because of the nature of the design... But gain? If you follow the schematics floating around the net that show the old and the new amps, the older amps had a LOT more signal driving the first overdrive tube than the later models.

I meant that the 70s channels has less volume compared to the skyliner. I just switch between the outputs of both these channels and the skyliner is louder.
BTW has anyone experience with 15" speakers for guitar amps?? Right now I use 2 12" in an open back assembly with a 20W 2xEL84 amp driving them. This setup can get mighty loud btw. But when I used the Dumple preamp with my Leslie (15") it was much smoother. I think I heard that SRV played some 15" . What setup did he have??

Dominik... in the case of the overdrive, the old Dumbles are like Boogies: the overdrive lead master feeds the overall amp's master volume. So, you have that... In the later amps, with the extra EQ, the lead channel output goes to its own EQ, and to its own master volume which then goes directly to the PI input. That is the reason one seems louder than the other.
Of course, the reason that is done is because the later mode has a huge loss at the extra EQ, and you couldn't wire that into two masters and balance the volume of the channels.

Where's the Los Lobottom come in then? Toto doesn't have a bass player?

I think Steve Lukater is a great player and a very nice guy. By the same token, for the amount of money he has invested in gear over the last 30 years or so, he arguably has the worst tone in the recording industry...
