Negative Feedback
... Typically, in a guitar amp, somewhere around 6-10dB of feedback is used. Most guitar amps have a "presence" control, which boosts the high frequencies. It accomplishes this not by actually boosting the highs in the forward path of the output circuit, rather by cutting the amount of high frequencies ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
