If your guitar is not playing, do not worry in most cases. A few months of vigorous regular exercise and a few good “sessions are all that it needs to get back to playing like the pro!” This is generally done by moving your neck slightly backward in a counterclockwise motion, which causes the upper strings to vibrate on the right and the lower strings to vibrate on the left. You can learn how to do this via a video tutorial here (it’s not just “solo” you should do in the woodsman’s shop, the guitarists themselves will benefit as well).
If your guitar is not playing, but you have a high-gain preamp, it must be connected to somewhere in the band where you can hear what the preamp is doing. It would be wise to use a different preamp, as if your guitar would not work, you should be able to get a very good and reliable signal from it.
What is a Gain Reduction?
When your guitar is not playing, this is a great time to talk about “gain reduction”. This is the removal of some of the highest frequencies of the guitar’s signal, which will result in slightly better performance. These gains will decrease in frequency as the sound is reduced as far as the ear can hear it, which is generally about two octaves. The exact frequencies we are talking about is somewhat related to the instrument, and what instruments the guitar is being played on. There are many different types of gain reduction available, but only two of them have been well documented which have a wide field of application: low-fidelity-only-and-unprocessed (LFD) and low-fidelity-both (LT) (sometimes called “Bass Boost”, or “Kick Boost”). In terms of signal path to the amplifier, LT is the easiest to implement, as the effects of its reduction are already built in to the signal path itself. There are some other approaches too on the subject. Many “unprocessed” gain reduction methods take this approach as well, but tend to have greater variations in the actual signal path from circuit to circuit.
The advantages of either method are usually in the area of “how does it sound”, not directly in the area of “how it makes music”, which is the most important factor. Gain reduction is a “how does it sound” technique, and the sound it makes is largely dependent on the nature of the signal path to the amplifier. As a rule
