Plexitube

True to the Music

Q: Can you explain the scoop voicings?

Each instrument occupies certain frequency bands in the com-
plete spectrum. Bass occupies the low frequencies and cymbals 
the highs, but most instruments (including guitar and the human 
voice) fall into the mid-range. The Plexitube's SCOOP voicings 
let you take out the mids that can get in the way of lead or vocal 
registers. The FAT voicing does the opposite and lets you domi-
nate the mid-range register.

Q: Can you explain the Contour control?

Contour controls where in the audio spectrum there will be a dip 
(SCOOP) or a bump (FAT). The Contour control sets the center 
frequency of the dip or bump. The Contour control is best tuned 
by ear to fi nd the spot that sounds best with your setup.

Q: Can I use the Plexitube for two different lead tones? 

Yes of course. We only refer to channel-1 as the rhythm chan-
nel for reference sake. The Plexitube’s rhythm channel is voiced 
very much like the original Radial Hot British distortion pedal 
while the solo channel has been voiced for a bit more bite. Both 
will yield exceptional lead tones. 

Q: Can I record 'direct' using the Plexitube?

Yes. Many musicians use Tonebone pedals to record direct. 
When you do, keep in mind that these pedals have been de-
signed to work best when connected to a guitar amplifi er. Most 
professional guitar amps use 12" speakers which tend to have 
lots of mid-range. This means that you will have to adjust your 
EQ to suit. A good place to start is by reducing the high end with 
the Plexitube's HIGH EQ control. Most players fi nd the high-end 
often needs to be attenuated when recording direct.
