Krister Bergman - Sweden
Krister recorded the following audio clip using his vintage Marshall 50 watt amp along with the PRX150-Pro into his Marshall 4x12 TV cabinet. The PRX150-Pro was set at max attenuation, allowing his amp to retain its tone and dynamics, while allowing Krister to record at a relatively low volume level.

Krister's comments on recording the clip:
The Power Rox attenuator is fantastic!
I found out that the amplifier actually is sounding better
without so much speaker (Greenbacks) distortion.
The clip was recorded at maximum attenuation.
And the fact that you can chose between 4, 8 or 16 as input impedance makes it VERY useful when you have the negative feedback wired to the speaker output jack so you can fine tune it so you can go between tight and clean and hairy and loose!
Krister's comments on the PRX150-Pro power attenuator:
" Thanks Jeff for inventing the PRX150-Pro, the best attenuator ever!
It is the Holy Grail of attenuators, nothing even comes close to it!
The Power Rox attenuator is amazing and totally transparent i love it!!!
Keep up the good work"
