LAA-CUSTOM PR30 User manual

Hello from LAA-CUSTOM!!
Congratulations on purchasing this incredible guitar amplifier designed in Italy by Carlo Sorasio
one of the most well known amp modders and designers in Italy and on businees since 2007.
The PR30 is 30Watts EL84 powered with tho channels able to cover all tones from an open clear
clean to a powerful crunch and massive distortion. Always amazing dynamic response, fast
attack with rich harmonics and body and a knockout punch!
The PR30 takes pedals very well and loves boosts, OD’s, phasers, flangers, tremolos, wahs, etc.The PR30 also has
an ultra transparent tube Series FX loop that takes time based FX pedals and rack units equally well.
PLUGGING IN
We recommend starting the amp on the Clean channel with the Bass, Mids and Treble at 5, the Volume at 6.
Set the crunch channel as Gain on 6, Bass, Mids and Treble at 5, the Level at 3. Then bring the masters up to taste.
After plugging in, you will notice instantly, the tight bottom-end, very focused mids and detailed chords and single
notes, that’s the LAA-CUSTOM sound.This amp cleans up remarkably well with the guitar’s volume control even
with the amp on higher gain settings.
We know you will love your new PR30. If you have any questions or help don’t hesitate to email us at
