One Control BJF Sonic Blue Twanger Amp In a Box

...back to the ‘blackface’ days at almost any volume!

The Sonic Blue Twanger is another in the line of ‘Amp in a Box’ designs by Bjorn Juhl, meant to model the sounds of a ‘blackface’ vintage amp. It can be used as a preamp, booster and overdrive pedal and will give your rhythm guitars an edge, and your lead guitars that limiting distortion effect of those ‘blackface’ amps run flat out.

 


As with many of the BJF designed pedals from One Control, the Sonic Blue Twanger is compact with 4 simple controls. The Treble control is really a tone balance (like on the original amplifiers) which increases and decreases a ‘shelved’ EQ setting.  Volume and Master controls work as pre and post volumes allowing you to vary the amount of clean headroom and distortion in the signal. Finally, on the side of the pedal is a Rhythm/Lead switch. In Rhythm mode, the pedal provides about 18dB of gain (-80dB noise level), and in Lead, about 40dB of gain (-74 dB noise level). 

Whether you are using the Sonic Blue Twanger as a preamp with any of the other BJF overdrive or distortion pedals, or as a stand-alone effect to achieve a more American sound, the Sonic Blue Twanger will take you back to the ‘blackface’ days at almost any volume!
