Sound City

To fine tune the strumming sound that comes from an electric guitar, a guitarist requires an amplifier. Sound City deals precisely in these types of amps, to make the sound track played appealing to the ears while making them loud enough so that the instrument is identifiable even in noisy environments like discos.

Active tone control, one notable feature of Sound City amplifiers, made its introduction on the Mark 4 models 50 Plus, 120 and 200 Plus. When all the "active" tone controls i.e. Bass, Middle, Treble and Presence are set at zero, the amp will not produce any sound even if the volume is set to 10. On the contrary, the "passive" amp that debuted on the Mark 3 is standard on DMI-era Bass 150 and Mark 4 50R PA, 50 PA Plus and 120 PA models. These do not limit the output of the amp even when all the "passive" controls are set at zero.

Another interesting feature is that most Sound City amps integrate the impedance selector in the rear panel, providing options between three selectable taps from the amp’s output transformer: 4 omhs, 8 omhs and 16 omhs. Sound City amps essentially have two types of inputs: Normal and Brilliant. Both of them also provide Attenuated input, which is suitable for instruments that are battery powered. Other features incorporated in some Sound City amps include Reverb In/Out jacks meant for providing the standard preamp loop as well as sensitivity switch situated on the rear panel, to make the amp louder in Position 1 and quieter in Position 2.
