The GK used a tube preamp simulator circuit called "boost". GK 800RB users include Red Hot Chili Peppers bassist Flea and Guns N' Roses' Duff McKagan. [4] The Marshall JMP Super Bass is a 100 watt amp. Lemmy, bassist/lead singer of Motörhead, used numerous of these amps to drive cabinets with four 12" speakers and others with four 15" speakers.
The best known and top-of-the-line RD, the Artist featured active circuitry with switchable bright mode, treble and bass boost, compression and expansion. It did not have a passive mode. The electronics consisted of a 9v battery powering a circuit board the length of the body, accessible from the back cover. It was also available as a bass. The ...
Otherwise, bass modulation became excessive and overcutting took place, with the cutter getting into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary. G. H.
The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric equalizers have much more flexibility in tailoring the frequency content of an audio signal.
A tone control circuit is an electronic circuit that consists of a network of filters which modify the signal before it is fed to speakers, headphones or recording devices by way of an amplifier. Tone controls are found on many sound systems: radios , portable music players , boomboxes , public address systems , and musical instrument amplifiers .
A typical sound reinforcement system consists of; input transducers (e.g., microphones), which convert sound energy such as a person singing into an electric signal, signal processors which alter the signal characteristics (e.g., equalizers that adjust the bass and treble, compressors that reduce signal peaks, etc.), amplifiers, which produce a ...
The key principle that drives the boost converter is the tendency of an inductor to resist changes in current by either increasing or decreasing the energy stored in the inductor's magnetic field. In a boost converter, the output voltage is always higher than the input voltage. A schematic of a boost power stage is shown in Figure 1.
The fittings are die-cast gold, and the pickups are covered by a plastic sheath. The access panel for the electronics in the Lyte is located at the back of the bass, secured with 4 screws. There are four different control knobs on the Lyte, consisting of a Master Volume, Pan, Bass Boost/Cut and Treble Boost/Cut.
