1 – INPUT
You can connect an active or passive bass to this ¼” input jack.
The BG250 Combo input stage is designed to adapt to any type
of pickup.
2 – GAIN & PEAK LED
The input gain should be set to the highest possible level without
overloading the input stage. To find the correct setting, simply
plug in your bass, play and turn up the GAIN knob until the
PEAK LED occasionally lights up. Then reduce the gain slightly.
When set, simply turn up the MASTER volume knob to start
playing.
3/4/5 – TONE Controls
The BG250 Bass, Middle and Treble controls are not your
standard Bass amp EQ. Standard tone controls boost or cut the
same frequency area when you turn the controls clockwise or
counter-clockwise. BG250’s tone controls intelligently address
several different frequencies when you turn them. In essence,
they not only provide tone control, but also contouring as well as
TC’s unique TweeterTone technology.
By adapting one or more target frequencies and bandwidths
at the turn of a single knob, BG250’s contouring tone controls
combine optimal tone shaping abilities with ease of use.
6 – TUBEDRIVE
Most transistor designs have tried to replicate the tube sound
using a single small pre-amp tube. Generally, they fail as they
don’t take into account the crucial characteristics of the full
pre-amp and power amp sections – both of which are essential
to the sound.
Tubedrive allows you to alter the “personality” and sound of
your BG250 Combo. The effects you can achieve range from a
small touch of classic tube amp response and character through
