Re: Guitar amp humming

--- Quote from: DavidTurner on February 01, 2011, 07:08:31 AM ---I have a correction: The guitar has a humbucking pick up and the pedals are not cheesy (in a stompbox relative way) or vintage. The player thinks it might be his 9v supply. Going to try replacing that and doing the telescoping shield thing.
Thanks to all who have offered suggestions.

A poorly regulated 9v supply willl cause all sorts of pedalboard hum.
You can build a decent supply for around $30. Most electronics sites (stores if you can still find one) will have kits where you just need to supply the transformer.
I have also lined a couple of hum prone Telecasters with sheet copper, soldering together all the seams. It was tedious but it made these guitars silent.
Good luck!

You can build one, or you can buy the Voodoo Labs Pedal Power 2. Great pedal with IEC mains, 8 outlets and has 2 outlets with sag control for pedals that like those "dying NiCad" battery sounds. super quiet, and reduced noise for me vs. the Godlyke Wall-wart power.
Cables - not the most expensive, but I've had very good luck with George L's for wiring my whole pedalboard. They are one of the lowest noise cables out there, and I haven't had a problem with the solderless connecters in 10 years.
Older, noisier pedals - we guitarists all have them - that pedal we can't live at out, but it may hum like crazy or be the tonesucker from hell. To combat that, put in a true-bypass loop pedal - basically a send-return loop that engages the pedal(s), but when it's off, they're out of the signal path. I have one on my board (lower left green box) that keeps all the delay, Phaser and analog chorus out of the signal path unless I want them in. Otherwise, my signal is all true bypass, save for one buffered Boss tuner. Worth getting; many people make them in 1, 2, 3, 4 loops per box. Keeley's looper is tiny and great for boards with small real estate.
Picture attached is my current pedalboard for home recording and live use, so it does get trucked around alot. Pedal Power 2 is underneath the Radial ABY switcher, which goes to a Dr. Z Mini Z and a 65 Bandmaster Combo, which Bob thankfully gave me great advice on speaker selection and a few other things.
Guitar ->
Keeley modified Dunlop Wah, with true bypass and fasel inductor. Has a nice boost when engaged.
Boss TU2 tuner
Keeley Compressor
Paul Cochrane Timmy Pedal (light dirt)
Barber Direct Drive (crunch)
Keeley Fuzz Head (plays nicely with other pedals)
Keeley Katana Boost
Mike's Tone Garage True-Bypass Dual Looper
- Loop A: 1983 Ibanez AD9 (4th effect I ever bought)
- Loop B: MXR Phase 90, 1987 Ibanez SC10 Analog Chorus, Boss DD6 Delay
Radial Big Shot ABY Switcher

Thank you Bob for catching my foot only half way inside my mouth!
Dave Barnett:
Does it hum if you plug the guitar straight into the amp without the pedalboard?
If not, then once you have a relatively noise-free baseline that works, you add one pedal to the system at a time until the hum returns.
