The Pre Booster is signal boost engine. This device adds a preset amount of gain with 4 knob control this lets you boost your signal for lead work, adjust between two different guitars with unmatched output (i.e., humbucker to single coils), or it can supply a permanent boost in a long effects chain where signal drop off is a problem.
This device use Class-A, FET (Field-Effect-Transistor) pedal offering up to 35dB without changing your signature sound unless you so desire You can fatten/distort your tone, brighten or mellow up the sound, add or subtract Bass, and add even-order harmonics!
Works great when put this pedal front of non-Master-Volume Tube amps to goose them into submission, as well as through Master-Volume amps to drive them much harder than possible with just your guitar alone. It also works very well on Bass, Acoustic Guitars (with Pickups) too.
