My shielded cable experience

Post by Tdale »

I made a dtdp switch right by the master volume. It's wired judt like the Clean/OD switch, and it switches the effects loop in or out of the circuit.

I did this because many of the players I know, never use th loop. I used shielded cable for both the send and return jacks.

When the loop is in the circuit, the sound is noticable less sparkling, and sound a bit muffled compared to when it's out of the circuit.

Very interesting to experience this first hand. I wonder what would happen if I removed the shielded wire from the input jack to the first grid...

Also. I think I might have turned the rock/jazz switch upside down.. The sound more more agressive in the jazz position as it's now.

The rock/jazz switch has two of it's poles soldered together.. is it in jazz mode when these two connect to the common poles, or is it in jazz position when they're not connected to the common poles?

Tommy, I don't know why you used a loop switch. Your amp doesn't have a loop. You have two jacks to add a loop. You should lose the switch and the shielded cable. Just like Dumble did it. The switch is silly as it does nothing. In your case it does since you used shielded cable there. If you had straight wire, the switch is moot.... What's the point of the switch. I don't get it......

OK.

When I started building, I thought about not including the Out-In jacks at the back. Those are for effects, right..or am I missing something?

Then someone told me that I should include them, just in case, so I did.

My concern was that the long wires all the way from the OD/clean switch to the "out" jack, and then all the way back to the Master volume, might pick up noise. Therefore I used shielded cable.

Then I thought; since I don't use the out-in option very much, why not include a switch, so that I can remove the jacks and the cables from the circuit. Then, if I ever need it, I can just switch it back in....

As for the switch not doing anything, that could be said about any switch, as long as you don't ever use it :)

And I must point out that it's not the switch that makes the sound go dull, it's the shielded cable. so if I change the cables, and use straight wire, the switch won't affect sound anymore, assuming that the wires don't pick up noise..

I would try it without shielded wire (and no switch) to see if it is quiet enough. Many amps are exactly like this. (I don't consider this too long in a normal d size box)
also, you have the jacks in, but you could wire everything without them, in a more direct route, and change your mind later. Wired normally, the jacks can be used for other purposes like sending a "preamp out" signal to some place like mixer or D.I. box, or another amp etc.
You could also try your switch idea with unshielded wire, giving the option of a shorter path.
