Valco FX IMP Boost Jr. Series Guitar Pedal
IMP Boost
Not your basic one trick pony boost pedal. The IMP Boost is a variable impedance AND boost pedal!
Use it at the front of your chain for a gain boost or use it at the end of the chain for a volume boost.
The Variable Input Impedance works best with passive instruments (guitar/bass) and allows tone-sculpting with or without the boost output engaged. Lower settings yield softer dynamics/transients with a notable ‘rounded/vintage’ feel and tone. Higher settings give a sharper high frequency response with a more direct/aggressive transient feel and more perceived gain. This makes for a great ’shaping’ control, where you can tune the pedal for its best response to the pickups you are using and how you want them to react/feel.
Adjust the impedance accordingly to tone sculpt and then use the output to determine how much, if any, of a boost you need.
