Guitar FX pedals
Also known as a stomp box
FX (like external units or software, or built-in to an amp) used with feet, and built into
boxes. FX include: distortion, tremolo, vibrato, chorus, etc. The first ones were larger in size as
they were powered by valves (vacuum tubes). These weren't very useful for performance. This
was replaced with the transistorised guitar FX pedals.
All FX can be daisy-chained.
Fuzz distortion has a more clipped sound and a fuller sound. Delay FX in analogue Bucket
Brigade device delay device (short delays which were delayed together as separate lesser).
All old circuitry based on valve technology. Early amps gave only about 10 watts of power
(equivalent to a ` bed-side table'). AC30 amplifier, which was a classic amp and known as well as
the Fender Twin Reverb. Iconic moment in amplifiers came about when the Marshall amp, created
by Jim Marshall, gave the 100 watt amp. Later, transistors were used instead, to reduce amp size,
and gave a wider frequency range. Not as `warm' or as `juicy' as the valve technology.
Spring reverbs, tremolos, distortion (originally done by accident by cutting a hole in the
speaker cone), EQ. Today, digital guitar amps are used.
Traditional Amplifiers: These featured in-built EQs, distortion, Bass frequency cut-off, Hi-Gain
output, Bass amps, DI inputs/outputs and acoustic amplifiers. Sometimes, bass guitar aps are used
on guitars. Cabinets (which are wired in parallel to lower impedance), can be
