![]() ![]() In short: an uninterrupted length of cable (including true-bypass pedals) works as a very weak capacitor, the same component used in your guitar’s tone control to filter out treble frequencies. Without getting too far into the weeds of inductance, impedance, capacitance and so on, buffers are essential to retain high end in a rig with lots of patch cables, true-bypass pedals and long leads between your guitar, ‘board and amp. ![]() Boosts can also ‘sweeten’ the sound of other pedals, without necessarily making them louder or more distorted – for instance a modulation pedal that sounds a little thin can be brought back to life with a boost.Īlways-on boosts can also function as buffers. ![]() A boost at the start of your signal chain can compensate for this volume loss, meaning the rest of your rig won’t need to be adjusted. Say you use two guitars across a set, one with significantly quieter pickups than the other. This is great for creating incredibly thick power amp distortion, however it does mean that your amp will be working at its upper volume limit – so maybe wait until the neighbours are definitely away…īut beyond simple gain staging, boosts have plenty of other applications. And if you’re using a tube amplifier, a loud clean boost in your effects loop can also push your power tubes beyond their distorting limit, even more so than you could do by cranking your master volume. With very clean boosts, you can even get good results placing them in your effects loop, making them effectively a second master volume control that you can engage with your foot. Place a boost pedal after an overdrive (and before an amplifier with enough headroom) and it will give a pure volume boost without introducing additional distortion – handy for solos! If you place a boost pedal before an overdrive (or a dirty amp), it will give you more distortion, slamming your signal into the gain section even harder.
