•  SETTING THE DEEP BOOST FREQUENCY & LEVEL

The Deep Boost is a gentle peaking curve with the maximum boost at the frequencies specified. But being a gentle 

curve, it will have a significant effect on frequencies above and below the chosen frequency. Take care when choosing 

the setting, as differences are much magnified when going from a quiet set-up at home, to a rig in a boomy venue. Often 

the lower frequencies will sound great at home, whereas the higher frequencies are likely to give more definition live.

•  When making adjustments to the Deep Boost, make sure the Volume is pulled up to activate the P-Retro. Also make 

sure that the P-Retro Active stack upper knob is in its centre click.

•  The factory setting is 6dBs boost at 60Hz. But try each frequency setting in order to decide which is the most suit-

able for your music and playing style. It may help if you turn the level preset up to maximum, in order to make each 

frequency more pronounced. Once you have decided, then re-adjust the level trim to a suitable level. If you are setting 

it in quiet condidtions, better to set lower than higher, initially.

•  BRIGHT SETTING

If turned on internally, the Bright setting will be activated along with the rest of the P-Retro Active functions, when the 

Volume knob is pulled up.

•  To check whether you want to use the Bright setting, first turn it on internally. Make sure the Volume is in its down 

position, and that P-Retro Active stack upper knob is down in its centre click. 

•  Then pull up the Volume and the Bright function should be apparent. Switch it on and off a few times in order be sure 

of its effect and whether you will find it useful.

•  FINAL STAGE

•  One you are happy with the internal settings, fit the final 6 pickguard screws into the bass and tighten them down, but 

not fully tight. Check the alignment is correct, and fully tighten all the pickguard screws.

•  You are ready to go, enjoy your P Bass & Retro!
