Does some magic to neck pickup. Stunning tones.

Adds roughly +15 db to the input. I wouldn’t recommend a boost with a modeler or solid state amp, but adding boost specifically to a tube amp is like adding another gain stage to your setup.

In this video I’m running gibson LP w/ SD nazgul pickups into an orange thunderverb a channel with max gain and a Mesa 4x12.

It’s just driving my tubes harder and adding extra gain! Big fan.

I've been using overdrive pedals to give me a "clean" boost for a long time, and I have never quite been able to get the brightness in my tone I've wanted without increasing the gain and making the amp start to break up. I've been on the hunt for a pure, clean boost that gives me the top-end sparkle without the grit. This is the one. My tone has never sounded better. I play a Gibson Firebird through a Katana 100w, and this baby makes my rig sing. Don't listen to the people who are complaining that the knob makes noise when you turn it; when would that ever be a problem? I mean unless you're planning on turning the boost knob in the middle of a song, which seems pointless to me. Just set it and forget it. If you're looking for a boost that is going to give your top-end some love and retain a pristine clean tone, this is what you're looking for. Makes overdrive/distortion pedals later in your chain sound loads better too.

Purchased this for my son. He loved and says it works great.

Works as advertised. Nice clean boost to the preamp. Possibly the brightest light in the biz haha.
