So why crosspost to sci.electronics.design?

sci - the hint's in the name.

I'm the one who crossposted. Guilty! I just wanted to hear from
these 3 different groups. It's a guitar amp circuit so it belongs on
AGA. It's a tube circuit so it belongs on RAT. And since it's
design, feedback, all that complicated stuff, I wanted to hear from
SED. Fair enough I guess! I understand that the perspectives here
are all going to be different. As to the Lord, he is well known to
dislike "3 legged fuses" and anything digital - but oddly enough he
does know quite a bit about the old-fashioned FETs of the 70s so go
figure, it's his personal opinion and not his lack of knowledge, it's
an informed opinion even if we may disagree. Me, I don't always
dislike solid state guitar amps, and nobody has ever had a problem
with transistorized guitar effects such as the classic Fuzz Face,
although I do dislike digital guitar gear probably because I first saw
the stuff in the early 90s when it had latency so bad that you could
hit a note and go make a sandwich before coming back and hearing it
come out of the speaker. So that's where I'm coming from and why I
crossposted.

As to the Lord's client list - never heard of ANY of them? Really?
Not even Meatloaf or Fleetwood Mac or Huey Louis? I can understand
that most people wouldn't like Yo La Tengo but they are cool I think.
And definitely the Dirty Dozen Brass Band rules - check out "Brooklyn"
I think that's their main popular tune. As to the Flobots - I love
the Flobots. My band actually covers "Handlebars" and they let me
play the horn solo (I only play guitar but I use an octave fuzz
there. It's kind of close. Kinda.) I mean, it's not like he has
done work for the Beatles but hey you know the Beatles are half-dead
already, life is like that, there's plenty of good music out there
today.


Electrical engineers tend to be suspicious of the subjectivity of
audio, not to mention the multitude of bad, bad circuits. Our world
involves measuring things, not asking drugged-out, hearing-impaired
rockers how they like the sound of our gear.

I designed one guitar amp. and that was plenty. Not only did some
goofy music store owners decide how it should work, but they wanted to
make all the money, too.
