OGRE TubeHolic Overdrive



As you can see from the name on it, the tube holic drive is an overdrive effect pedal, which succeeds a historic and traditional overdrive pedal, realizing the overdrive sound from a vacuum tube rich in warm and harmonic constituents.

Besides, the tube holic overdrive is one of the masterpieces from OGRE to become the legend of a new overdrive pedal in this period. As well as unique enclosure design not seen on any effect pedals, the sliding-type cockpit head cover system, which is the first adopted in the world, is an exclusive design and system devised by OGRE in order to protect without hurting players’ tone setting developed for a long time during the wild play at the stage.

And a wider frequency band than that of current tube sound overdrive, strong gain and high output level, a long sustain sound, which shows genuine value during the solo play, and symmetrical clipping tone using the NOS diode can be enough for many players to experience a new world of overdrive tone never felt on overdrives before. As other players, the player can use it as a clean boost, do not only the traditional overdrive setting but also the powerful overdrive tone setting, which is matched the music in this period. Thus, the player himself can widen more the range of his own overdrive tone making. High gain & long sustain – Capable of displaying its genuine value at any solo play.
