Sometimes it's the cable

[culturejam]

I spent about an hour this afternoon swapping out tubes to try to remedy an "almost no volume" problem with my Randall Diavlo 20. It worked perfectly the other day when I turned it on, but today I got no sound until I maxed the master and channel volume. Swapped out the power tubes first. Then V1. Then the other preamp tubes. Then the PI.

Then I unplugged from my pedal board and tested with just the amp-to-board cable. Same thing.

Then I pulled the amp and tried a different amp. Same thing! Aha!!!

Turns out it was the amp-to-board cable. 

TL;DR - Sometimes it's the cable.

And sometimes you go through all that and it's your guitar's volume knob turned all the way down ...

Hah, one time I was swapping out patch cables like crazy, trying to find the bad one... then I spotted that the I/P Gain on my (non-true-bypass) ? Flange was on zero. (It affects the bypassed signal as well.)

In my case, it turned out to be the speaker cable. Sigh.

In my case, it was testing with a guitar with a known bad volume pot which actually had a piece of masking tape on the back which said "Waiting for new harness".  Some days I am all looks, I tell ya.

Bad guitar cable.
Bad speaker cable.
Cable not plugged all the way in.
Forgot to put IC in the socket.
Volume all the way down.
Didn't connect the ground wire.
Didn't connect the power wire.
Forgot a component.


Most of the time, it's the object between guitar and amp (ME!)

I've done pretty much all of these, but my top favorite to do is forget to turn on the power.

This gave me a good chuckle. I feel the same way some times, but if I had to depend on my looks, I'd starve.

Last night at a rehearsal, couldn't figure out why my guitar signal was coming through the wedge monitors but in-ears were dead. Checked volumes etc. Took 10 minutes to figure out the in-ears weren't plugged into the aviom.
