Explanation Of Amp-Types - TC Electronic G-System User Manual

TYPICAL SETUPS
If you an experienced gear "nerd" already, this page will not apply to you. This page gives information on a few
basic issues regarding amp types.
Generally said - all setups include both a pre-amp and a power-amp. This applies whether it is a Head, a Combo or a split
system with separate pre/power-amp. How to enter and exit these components is a different story. However, "Send" is
usually equal to "Pre-amp out" and "Return" is usually equal to "Power-amp in".
Pre-amp
The pre-amp generates your basic tone. It usually has 2
or more channels. E.g:
Channel 1 Clean
Channel 2 Lead
The Pre-amp could also be viewed as an advanced
overdrive or distortion pedal.
Power-amp
The power-amps main object is to amplify the sound
generated by the pre-amp and effects that are placed in
front.
Head
A "head" is a pre-amp and a power amp built into one
box. It is as simple as that.
The Input on the front is the pre-amp input.
The effect loop Send – is the pre-amps output.
The effects loop Return – is the Input of the power-amp.
Combo
The Combo amp is identical to the Head but also has
built in speakers – hence the "combo" or "combination"
expression.
We are quite aware that not all amps are built and
labeled exactly alike and the generic explanations above
must therefore be considered as a basic guide. We also
recognize the importance and tone-differences of the power-
amp models, tube-types etc. - This page is a reference for basic
understanding of the principles of guitar amplification only.
