Pitfalls and Common Mistakes
It is very important to have a line box or a preamp with an input that is designed for
guitar (or bass) before the signal from your
guitar enters your computer.
All of the real amplifiers we have simulated
have a 1 megohm input impedance, and for
the plugin to recreate the sound correctly,
the guitar input to your system must have a
1 megohm input impedance!
Line inputs on mixers or sound cards are
usually low impedance inputs (around
10 kilohms) which in most cases makes your
guitar sound dull and lifeless.
Tip: If you don't have a line box or preamp, you could always check your
stomp boxes. If the stomp box doesn't have the “true bypass” feature,
chances are that it will work just like a high impedance preamp when it's in
bypass.
If you want to check the impedance in the manual of your preamp, go to the “
Technical
Specifications
” section and look for “
Input Impedance
”. In order to get the most accurate
guitar sound and amplifier simulation, the input impedance should be 1 megohm (1 M
Ω
)
(
have we repeated this enough times now?
). A value ranging between 500 kilohms and
4 megohms should also be OK.

like a Jazz Bass!")
