Brother Clip

[Guitarman18]

aside from MANY clams!! If you could only hear it as it is in my head before it fails to come out my fingers!

Brandon, you're not the only one who suffers from that.
My fingers seem to produce a sound more akin to a trouser trumpet, than how I hear it in my head.

Thanks for posting the clip, lovin' the tones!

Cheers,

Paul.

LOL, You said "trouser trumpet" !!!!!!

... what creates that instantaneous increase in the note volume just as the string is plucked? Your 5th note is an example.

Is that something that's inherent in any particular dumble design, or is it a secret that only some know.

Did I mention... really nice playing and great sound.

Interesting that this is heard as a volume increase. From what I see on the scope, it's not, but it sure sounds like it.

I believe that some of the harmonics jump out after the initial attack, and like Brandon said, it comes only on the high plate amps. It's really best if the chirp on attack is very noticable. I also feel that a nice smooth finger vibrato helps bring out the bloom.

Gotta love that for slide playing!!

Great clip Brandon, a few clams but who cares, what's life with out clams.

I've accepted clams as a part of life......

I've decided I like em - some butter and maybe some white wine - a little steam mmmmmmmmmmmmm

Could you explain "chirp"?

My guess would be that rolling off the highs, so that the tone more resembles a horn (which has a lower attack and then blooms louder), can help make the brain think it's hearing a bloom even if it isn't.

But there still needs to be some electrical contribution that actually makes the signal move closer to a horn envelope.

Compressing the attack, so as to delay the decay, seems like one way; and I'd think that power supply sag is probably the way to create 'compression' bloom, along with asymmetric clipping.

So what is the best way to get the right kind of sag; and what is the best way to get asymmetric clipping? Would it be by playing with the PI section balance or the pre-amp stages plate/cathode relationship; or both?

I think the chirp is just the way the pick sounds when it strikes the string.

I don't know what enhances it or what the technical explanation is.
I'm sure somebody here does though.

I don't think these amps sag much if at all. The transformer and solid state rectifiers are just too stiff to allow for much if any.

Every sound clip [that I have ever heard] displaying a single note 'horn' like envelope bloom, seems to exhibit a very soft attack. If the soft attack is not from sag then I guess it is merely from the OD being on.

Yet the signal sounds relatively undistorted. I guess the rolled off highs could account for that.

To me it sounds a bit like the note is incurring that intermodulation effect that can be quite noticeable when certain intervals are played - except it's coming from a single note. I guess a burst of harmonics could explain that.

I wonder if an amp, that has this single note bloom quality, produces a particular signature of asymmetry, in any particular stage, as it clips? If so, I think it would be very interesting to identify.

When I built some tube mic pre-amps years ago I took the time to drive them towards clipping with a sine wave, so as to observe the asymmetry of the wave as it clipped - as I was seeking a very balanced soft (yet asymmetrical) clip. I think small changes in the surrounding parts were enough to easily alter the asymmetry, but don't recall.

[Structo]

Well, you obviously have a more technical mind than I do.

I too would like to hear if, anybody is capable, what contributes to the type of tone the ODS produces.
I'm sure it is a combination of things or a sum of all the design features on these amps.

From the local feedback, snubbers on V2, the OD design, to the use of a Dumbleator in the FX loop, etc. that contributes as a whole to the signature tone of a good ODS.

I don't think I've heard that horn like envelope in every OD sound clip I've heard. Therefore I assume that a design formula for it exits; unless it comes from the use of a Dumbleator. Brandon mentioned he used his Loop-a-lator is this sound clip.

[Funkalicousgroove]

it could be that i pick fairly lightly...

[LPSGME]

...could be. I'm sure technique helps bring it out.

But is there any particular posted design that is most similar to amp you played in this clip?

If so, are there also any part value differences that you don't necessarily want to reveal.
