​Bjorn's Description
The Sonic Blue Twanger is another design in the Amp-In-A-Box’ series by One Control and BJF.  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 any volume.

One Control - twanger - sweet tone

By: on 2 August 2020
This little fello is basically a 'fender tube combo amp in a box'. That's how good the tone came across when it was set up against a fender tweet blues junior 2017. In addition, it has a rhythm (18 db) and a lead (40db) interchangeable switch which allows the player to have control over the pedal. The rhythm section blends very well with other clean boost and light overdrive pedals. The only set back is the location of rhythm/lead switch which is on the side of the pedal.
