The dB33 vacuum tube boost is specifically designed for metal guitarists who want to push their amp. The response of this pedal will make your tone stand out in the mix. Lower frequencies are less boosted than the upper frequencies. Due to this response, notes become more pronounced and will sound less dull. This pedal will give you a maximum boost of 23.5dB which is equal to multiplying the input signal by 15 times! The signal path of the dB33 is completely analog, using only passive components and a vacuum tube. To obtain a clean boost the vacuum tube needs enough headroom. This is established by a high voltage converter which is implemented in the design. Quality components are used such as precision grade metal film resistors and polypropylene coupling capacitors. A sturdy metal shaft potentiometer and die cast aluminum housing will ensure a long life time. Last but not least, true bypass relay switching is used to ensure your signal is not affected when the pedal is not in use. The dB33 vacuum tube boost is the ideal match for every metal guitarist who needs to add some aggression to his sound.
