A diagram showing the wiring of a Gibson Les Paul electric guitar. Shown are the humbucker pickups with individual tone and volume controls (T and V, respectively), 3-way pickup selector switch, tone capacitors that form a passive low-pass filter, the output jack and connections between those components. The top right shows a modification that ...
A line-level attenuator has lower power handling, such as a 1/2-watt potentiometer or voltage divider and controls preamp level signals, whereas a power attenuator has higher power handling capability, such as 10 watts or more, and is used between the power amplifier and the speaker. Power attenuator (guitar) Guitar amplifier
These amps were the Princeton, the Deluxe and the Professional. The Princeton was a small six watt amp with an 8" Jensen field-coil speaker. This amp had no controls as it was designed for the guitar to solely control the volume and was simply turned on by plugging/unplugging into the wall plug.
As time goes on, there are more and more switches being developed and manufactured across the world. Some are by new manufacturers, some are collaborations between companies and manufacturers, and some are consumer made.
The arrangement of parasitic resistances and capacitances in the guitar, cable, and amplifier input, combined with the inductive source impedance inherent in this type of transducer forms a resistively-damped second-order low-pass filter, producing a non-linearity effect not found in piezoelectric or optical transducers.
Block diagram of a basic class-D amplifier. Note: For clarity, signal periods are not shown to scale. A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers.

The Standel Company is an American company that makes guitar amplifiers.It was founded in 1953 by Robert "Bob" Crooks in Temple City, California.Standel (a portmanteau of standard and electronics) was the name of Crooks' side-business of radio and hi-fi repair, located in his garage at 10661 Freer Street, Temple City, California.
