Switching is a bummer

[Reeltarded]

Taking out a stage or flipping channels is one thing, but adding a global control or a ganged control.. or a selectable global control with a ganged or unganged condition.

Any extra level of complexity. Booyah, dumbass. (Cue sad trombone)

Whaaaaa whaaah whaaaa whaaaaa

It would be so much easier if the physics of electronics were totally based on switching by simply shunting to ground. Amplifiers would look more like overly decorated Christmas houses in the middle of August.

You finish your big ground loop then take signal from a place over by the inputs. Easy!!

Whaaaaa whaaaa whaaaaaa whaaaa

Yeah, ok. So I am losing my mind. Ehhh

Yeah, if channel switching was so easy we'd all be doing it, right ?
<cheers arise from the Dumble crowd>

So if things were different a single 4066, for example, could control 4 different functions instead of having to use all 4 sections just for one function.
a) select path 1
b) select path 2
c) shunt (mute) path 1
d) shunt path 2
This is how the MusicMan 50 and 100 RD models accomplish their channel switching, 4 "switches" to change channels.
The shunt/mutes are surely needed in a high gain situation, and if you're not boosting gain why even have the second channel.

I can see why the relay thing is still used.

You may be losing your mind but this post doesn't prove it.

Two channels that switch pre and post so all in or all out. The NFB has three conditions lift-8R-16R. The NFB setting happens per channel.

This is making me angry because I keep finding an open switch somewhere.

grrrr

I've been studying multichannel preamps lately. It's amazing how many of them suffer from channel crosstalk because of crappy switching schemes.

You'd think that would be the easy part.

................ Yeah, ok. So I am losing my mind. Ehhh

Whenever I say that, my wife says "Too late!" True story.


In any case, you're not losing your mind; you're gaining knowledge. A mature mind, that still is gaining knowledge, has to build additions to house all that extra experience, memories, analysis, and massively redundant error correction. Sometimes you can feel it ....... e-x-p-a-n-d-i-n-g.

Was on the horn sorting out a problem with Mike Bendinelli (Mesa's chief engineer) one day about 2 - 3 years ago. Besides getting the problem sorted out, he mentioned the Mark V about to be released has what, 47 relays?!? So that's how ya do it. Lots n lots n lots of relays. I am NOT looking forward to the day when I have to figure out which relay has gone dodgy in a Mk V.

They all went bad. I fix those by soaking the amp in whale oil.

Ambergris, Miles. The source of all great tone.

[Reeltarded]

The tone is in the switching. Another win for physics.

[Blackburn]

Fulminated mercury... Chemistry wins.

I fix those by soaking the amp in whale oil.

and you have to get the whale to hold still while undergoing this procedure.

[Reeltarded]

Figured it out. It's impossible.

Anyone need a used whale?
