I recently purchased a boost pedal for my pedalboard, and was wondering, when do I use it? Just during solos? Or in chorus's as well? I would like to know the correct usage of the pedal, any help is appreciated!
Basically you use the boost pedal any time you need an extra bit of volume to stand out. Typically this is during a guitar solo, but yes, sometimes it is also useful in a song's chorus if the whole band picks up the energy a bit. But as with all effects, use your ears as a guide. Obviously you don't want to use it all the time, but for certain moments in a set it can be very effective. Especially with a tube amp, you can get a great dirty-ish tone. I like to set my amp right on the edge of breaking up (on the line between clean and dirty basically), so when I kick in the boost pedal it drives the tubes a bit harder and gets a nice overdriven tone, but I have the option of turning the boost off and playing a bit lighter to keep a mostly clean sound.
It's worth mentioning though, that the use of pedals comes down to personal preference, and every guitarist needs to find their own sound. Experiment a lot, both alone and with the band, and see what kind of sounds you can get out of it.
Generally, a boost pedal can also be a great tool when you have multiple pedals running through your pedal-board. It gives an extra "boost" to make up for some signal loss and the "lost flavor" when the signal travels down multiple pedals.
