Electric guitar combo design
Obr, Viktor ; Šebesta, Jiří (referee) ; Dušek, Martin (advisor)
The text of this bachelor´s thesis describes designing a construction of electric guitar combo. The first part of the project deals with history of guitar amplifiers and theory of design of individual components. The second part includes actual designs of guitar effect units (fuzz and tremolo), correction preamplifier, power amplifier with integrated circuit TDA7293V, power supplies for all components and choice of speakers for guitar combo. All effect units and preamplifier are also simulated in PSpice. In the last part there are results of measurements of all components and the whole combo.

Effect amplifier for electric guitar
Kočiš, Martin ; Brančík, Lubomír (referee) ; Kratochvíl, Tomáš (advisor)
In the first chapter, the thesis concisely describes perception of harmonic frequency components by human ear. The second chapter introduces the reader into purpose of guitar effects and summary of usual types, which is possible to meet on the market. The third chapter contains functional description of chosen effects including designed schematics and simulations of functionality in time and frequency domain, eventually unrealized solution. The device contains input highpass filter with emitter follower, booster, overdrive and clean amplifier, circuit for octave-up frequency shift, delay line, output emitter follower with lowpass filter and power supply for all these circuits. Selection of the effects and its controls was subordinated especially to use in alternative rock music. The design is based on simulations executed using OrCAD PSpice. The realization process and the measurement is described in the fourth chapter and the last chapter contains conclusion of the project.

Design of preamplifier for guitar effects generation.
Müller, Radek ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
The topic of my bachelor's project is preamplifier blueprint for creation of certain guitar effects. Output signal from an electric guitar is often modified for musician's needs. My objectives are to discover options of signal modifications, electronical solution of preamplifiers and final effect on sound character. My targets are to design and construct two chosen guitar effects, which will distort the output sigal from an electic guitar. Both wirings will be tested by computer simulation and then will be compared with real circuit wiring. Its necessary to box up the printed circuit board and place control and signal elements to accesible place.
