Check the listing for details. Guitar pedal J-FET Dual Rectifier - Dr. Boogie High gain distortion. Condition: New. Listed at 129.99 USD. Guitar pedal J-FET Dual Rectifier is a transistor analogue of the cult amplifier Mesa Boogie Dual Rectifier Solo Head, also known as Dr. Boogie high gain distortion. Instead of tubes, the amplifier uses original high-quality MMBFJ201 field-effect transistors from ON Semiconductor, whose characteristics are very similar to a classic tube in an amplifier, they are low-noise and give good attack when overloaded. The device is designed in such a way that it allows you to achieve excellent overload even on pickups with low output voltage and low sensitivity. For sensitive pickups, the gain knob level is usually enough to 1/4. The device is battery powered from a 9V 6F22 element. To avoid discharge, the battery is connected only when the Jack input connector is turned on. In our products we use high-quality film capacitors from global manufacturers such as WIMA, Epcos, Hitano give excellent soft tube sound. Unlike serial devices with ceramic capacitors in audio paths. We also use metal film resistors that do not change their resistance depending on temperature, which also affects the stability of the voltages on the transistors and the entire circuit as a whole. All products are assembled by hand and tested, quality is guaranteed. Type of effect: Analog, high gain distortion Controls knobs: Volume, Gain, Presence, Treble, Mid, Bass Bypass type: True 3PDT switch Power supply: 9V DC center negative Works on batteries: Yes (battery not included) Power consumption: 10 mA.
