Features:This hand-made Dumble based high quality amplifier has developed a reputation for having a silky smooth, pliable and touch-sensitive brand of overdrive. The amp is incredibly versatile and you can easily play any kind of music using it. It is famed for its singing "clean" overdrive channel that is very responsive to the touch of the player. It produces a tone somewhere between a Fender and a Marshall, with a strong midrange and a balanced voice. The circuitry is unique in that the overdrive is produced in the preamp stages, the power amplifier does not readily distort, giving a huge clean sounds with a big tight bottom end.There are two inputs: a normal input which goes directly to the first preamp stage, and a FET input which goes to a FET preamp which is intended for use with guitars with low output levels or acoustics. The FET level is adjustable using trimmer potentiometer inside the amplifier. The first preamp stage is followed by a passive tone stack with adjustments for treble, middle, and bass. Switching options include Bright, Deep and Rock/Jazz swtiches. The signal is either fed into the power amplifier (for the clean channel), or into the two-stage overdrive section. Sound Options: clean, clean with boost on, overdrive and overdrive with boost on.The clean channel is big sounding. Soloing on the clean channel is powerful. It has more head room than one might ever use, it's amazing how clean the amp is at very high volumes. This amp really lends itself to the different sounds of each individual type of guitar. The overdrive channel is really quiet at high gain and is adjustable using trimmer potentiometer inside the amplifier. This way the player can set his own overdrive voicing, goin from Brown to Plexi.Specification:Model NO.: ODSAmplifier Name: Dumble ODS Overdrive Special guitar amplifier head 50WSpecs: Hand Wired Construction Circuit BoardTubes Brand: Ruby, Shuguang, JJ, EH (JJ 6L6GC *2)Components: Pot/Bias Japan, Sweden brandPower: 50WWeight: 20kgShipping Time: 20 DaysPackage: Strong Carton BoxTransport Package: Double Strong Carton BoxOrigin: ChinaCustomized: AvailableCertificates: CE, ROHS, FCCDimension: 86*46*31(cm)With footswitch and booster100W is available tooHS Code: 8518400090Power: 50Watts, with power cutChannels: Two Channels, clean and overdriveControls Ch. 1: Volume, Treble, Middle, Bass, Master Volume, PresenceControls Ch. 2: Volume, Treble, Middle, Bass, OD Level, Ratio, Master Volume, PresenceSwitches: ON/OFF, Standby,  Manual/footswitch engage mode for boost and overdrivePower Tubes: 2 x 6L6GT JJ tubesPreamp Tubes: 3 x 12AX7 JJ tubesRectifier: Solid StateFeatures: Dual inputs for each channel high and low, Effects loop send and return, External speaker, Pilot light, Footswitch for boost and driveSpeaker output: Switchable Impedance of 4, 8, and 16 OhmsSpeakers: Celestion Gold Alnico 12″Power Options: 50 Watts (2 x 6L6GT) and 100 Wats (4 x 6L6GT)
