Compressor and Boost Pedals: Control Before More Gain
Compression changes the envelope; boost changes level and often frequency balance. Decide which problem comes first.

Compression can reduce peaks, raise quieter detail and extend sustain. Attack controls determine how much pick transient passes before gain reduction; release controls shape how quickly the level recovers.
A blend control can restore dry attack alongside the compressed signal. Meters or gain-reduction indicators help repeat settings, but the musical result remains the decision.
Place boost for the intended result
A boost before gain drives the next stage harder and may add saturation more than volume. After the main gain stage, it has a better chance of increasing output if the amplifier still has headroom.
Treble boosts, mid boosts and full-range boosts reshape the signal as well as raising it. Match that voicing to the guitar and mix.
Manage gain and noise together
Makeup gain raises everything after compression, including pickup and environmental noise. Set output at unity first, then add only the level required.
Check headroom with the strongest pickup and hardest attack. A compressor that clips internally or a boost that overloads the next input can change the sound before the intended gain pedal.
