What Are You Working On?

Working on today? Trying to get some nice photos of my guitars. It's not that easy.

Good to see you here mate!
 
Went to practice last week with my 594 HB and 594 SC SH (back hurting, and dayum they're nice).
Plugged in the HB and found that the switch to treble/bridge pup resulted in severely muted output, to the point of being unusable.
OK, switched to mid and finished the song.
Next day at home I took it out of the case, same thing. Decided to throw the switch numerous times to see if it was just dirty/contaminated or what.
After about 20 times I could hear it trying to switch in. Grabbed a can of compressed air I had lying around and shot it multiple times. One attempt had the propellant come out and soak the switch.
After that it worked intermittently, and then later the switch became very sticky to move... rough feeling.
Decided to go get some Deoxit D5, and that immediately fixed the issue, and now the switch is perfect.

TLDR... Deoxit rocks!

I'm interested in this, did you tweaked the PI by ear, or by numbers?
Sort of both.

For those not familiar, most Dumble style amps have a trimpot that can be used to adjust the balance of the PI.

I tried adjusting by ear and didn't hear much difference by playing a little, putting the guitar down, adjusting, and playing more.

I also tried adjusting with a looper in front and didn't hear much difference.

Then I stopped running guitar signal in and measured voltages, played again, and still not a ton of difference.

Finally I thought "well let's just run a sine wave in the input and activate everything and listen to what happens. And I'll also record a few seconds into logic and use a frequency analyser to see what's going on..."

I could see changes in voltage based on master volume settings AND at different frequencies.

I think I ended up using 880hz as the test and was able to get the PI voltages within the recommended 6v difference between the plates.

The play test confirmed it was where I wanted it. Big cleans with little to no sag from the output section.

Lush. I may tried that with my Fillmore but at this stage I'm terrified if I change a single thing I will **** up a perfect amp.

It's still may not stop me from faffing around, I finish my 5 years warranty in March.

Thx
 
In 9 days, the DC Blues Society challenge will be held. The winner goes to the International Blues Competition in Memphis in January. I’m playing with a group called Nella B and the Noise. We’re going to burn the stage down musically. Our last song will be a go go Blues. Only in the DMV, my friends. I’m practicing as much as possible, with ice and compression gloves at various intervals to keep the hands stable. The triple soapie will rule.

Bring the heat, brother! And the funk, of course.
