AMT BC-1 BASS CRUNCH 2CH JFET EFFECT PEDAL

The BC-1 is a 2-channel preamp with one clean channel and another dedicated overdrive channel. The clean preamp is controlled by the top row of knobs that include: LOW, MID and HIGH for sculpting the tone, plus GAIN and LEVEL to control… Well, gain and level. All of these knobs behave exactly as you would expect.

The knobs in the middle row are named identically to the top row, but the GAIN knob introduces dirt – from subtle crunch to roaring overdrive. However, you also get 2 toggle switches that add to the control and flexibility of the drive circuit. The first one is connected to the MID knob, and it allows you to define a notch filter target frequency – choose between 230 Hz, 350 Hz and 500 Hz.

Similarly, there is a notch filter toggle switch that affects the frequency spectrum right before your signal enters the gain stage of the drive circuit. You can choose to leave it OFF, or give it a notch down at either 400 Hz or 700 Hz.

The lower row of controls holds 2 knobs: BLEND and VOLUME. The BLEND knob mixes the signal between the two channels (clean and drive). If you dial this knob fully counterclockwise, you get only the clean channel – and vice versa. The VOLUME knob sets the master output independently of the various gain and level settings.

Finally, the footswitch on the right allows you to switch between HI and LO, which relates to the input sensitivity, and the left-side footswitch punches in and out the DRIVE circuit.
