 You train boost function to the various parts, there is a bypass function of the amplifying stage and/or with considerably they are many functions, but, circuit constitution being simple, is straight. The designer makes that it is the encounter group which is experience rich. It has become two of the channels entire constitution is divided by two channels roughly and puts out to crunching and the clean channel and, may be warped well. As for the clean channel having become circuit constitution of fender system, the overdrive channel seems that becomes the circuit of Marshall type. Especially with " [purekishi] " mode the simple old Marshall circuit becomes, mind air of the designer such as place is felt. The distortion channel gain and master are 2 systems, the using selfishness is appealing. To be administered by also the phase invertor, it may be able to correspond to the cabinet speaker of various types the device by the fact that it changes the negative feedback quantity, is.

 Because the doubtful part is some point in the schematic which is made reference, it cannot criticize unconditionally, but, using high resistance, it reaches, the part where the circuit floats completely it is discovered. In addition, it became matter of concern to change the 2nd bias of the overdrive channel DC with step. Change of the channel seems that uses relay. Because the wide timbre can be made from simple circuit, use with any kind of music genre it may, is. Also function of [ehuekutosendoritan] and the like being sufficient, you can ask that even from the schematic it is the amplifier which answers to also professional request completely.

 Are THD and cooperative relationship to seem, the baseplate seems that uses things such as heavy duty & high reliance. Also the part has used metal membrane resistance and [huirumukon] etc of BOX type. The POWER tube is placed by the sub chassis and has decreased the influence of the vibration.
