High Gain Overdrive Low Noise Floor

Lnas are designed to minimize that additional noise.

High gain overdrive low noise floor.

The level of the noise floor determines the lowest strength signals that can be received and therefore the noise floor level is an important characteristic of any radio. It does affect sustain and various other factors but they are outside the scope of the question. Adjust the gain and volume controls. The ace up the tb s sleeve can be found by switching the left hand circuit to 909 mode which introduces the high gain tendencies of a gas 909 overdrive to the tb drive.

On one side of the gain switch you get the delicious tones of barber s ltd overdrive and on the other the unlimited distortion pedal. At low volumes say 9 o clock on the dial this works as a neat little overdrive but keep turning it clockwise and the gain and the volume keeps coming. The noise floor can be defined as the measure of the signal created from the sum of all the noise sources and unwanted signals within a system. If you have a 100 watt tube amp it s probably going to make more noise than a 15 watt tube amp.

Also if your amp is designed for high gain settings it will most definitely make more noise than an amp designed to run cleaner. The amplifier s power rating wattage can impact the noise floor level. A noise gate will act as a gain reducer until you send a signal over its threshold so having a noise gate first is a good idea. Well the general advice to avoid noise is to use as few pedals as possible as each one raises the noise floor.

This all behaves like running a couple dimed overdrive pedals in series with tonnes of liquid sustain and squealing. The final destination is a thick fat and open distortion with a little fuzz overtones that makes for amazing 70s metal tones. Residual noise forms the noise floor.
