A booster pedal of some kind is always worth it in a one guitar band.
The TC Spark Booster is a good shout.
I used that for a few years but have just moved to an Xotic RC Bass Booster which is a great pedal.
You wouldn't have thought there was all this great new music in rock and metal judging by the bands nominated for the Grammys...
Foo Fighters nominated yet again? Zzzz.
At least you wouldn't have suffered from the dreaded line that I once received:
"Can you turn it down, please? I'm trying to have a conversation here!"
