Anyone know who makes the best "no single coil hum" pedal out there? There's this one place we have started to play regularly that has a lousy electrical grid in house. I already needed something for my Strats and Teles but I have a Les Paul with P90 pups coming so I know I will need something for sure to stop this racket and aggravation. If you have a suggestion for a "No Hum" pedal, would you please let me know if it affects the tone in any way or if it is "invisible", tonally speaking. Any thoughts or product suggestions will be greatly appreciated.
