Olsson BJF100, Owner'S Manual

Page: 4 / 12

INTRODUCTION
Congratulation on purchasing this new amplifier, designed by the well known amp and pedal
designer Björn Juhl (BJF) in cooperation with John Olsson at Olsson Amplification in
Sweden. It’s an unique collaboration and this amp has it’s own sound and possibilities.
The BJF100 is a 100W EL34 powered two channel amp capable of producing many styles
of music. Both channels can produce distorted sounds where number one can go from
seemingly clean to fairly heavy distorted enough to play heavy music; and number two can go
from about clean sounds to break up (crunch). The idea is that most guitarist, when running
a clean sound, usually don’t want it to be clinically clean but wants some shimmer and
some limiting on the transients, so the second channels can set this gradually. Typically this
is a function produced in the power amp section but here we have successfully moved that
function into the preamp instead. Believe it or not but this 100W amp will sound great also
at bedroom volumes. Just turn the volume controls down and the sound will stay the same.
Also note that the clean and the overdrive channel has no components in common, resulting
in two optimized channels which is not very common in this type of amp.
Both channels comes with an effective three band EQ and Presence control.
Due to the unique pre-amp design the BJF100 takes pedals extremely well and the transpar-
ent FX-LOOP takes care of your time based pedals exceptionally.
The BJF100 amps are hand built by skilled engineers in Sweden and crafted with the finest
material for flawless performance.
We hope that you will love this amp and if you have any questions don’t hesitate to contact
