Compressor Pedals
An electric guitar compression pedal will give you incredible volume control.
You set the threshold, and the compression pedal will increase the lows and minimize the highs to stay within your levels.
Compressor pedals commonly control volume, tone, attack, and sustain.
You will find compression pedals from brands such as MXR, Maxon, Electro-Harmonix, Wampler, Keeley, and Xotic.
