2. Timeline of Guitar Amplifiers  1930’s- First Amps are made  1947- First solid state amps are made  1990’s- Modeling amps are made

3. Tube Amps  First introduced in the 1930’s, tube amps use vacuum tubes to increase the power of a signal  Requires tubes to be replaced periodically  High-end amps are generally tube amps

4. Solid State Amps  First introduced in 1947, solid state amps don’t use tubes, based on semiconductor circuits  Weigh less and are less expensive than tube amps, but generally not as good

5. Modeling Amps  Modeling amps, introduced in the 1990’s, were designed to emulate well-known tube amps, sometimes incorporate tubes  They also have built in effects
