 GAS-728B NG Clean Boost / Overdrive for bass
909B mode Rocker switch ON: Gain boost, 3x more gain than in standard 808B mode
Deep boost Rocker switch ON: The GAS-728B NG has two deep boost switches, separately for GAS-707B NG and GAS-808B NG. The deep boost lifts the lower frequencies, the overall sound stays defined without getting muddy.
GO! switch GO! rocker switch ON: Switches the GAS-808B NG into momentary action. The GAS-808B NG is ON only as long as it is pressed. Ideal for short 'fill ins' or controlled feedback. If the GAS-808B is pressed in BOLT mode with GAS-707B activated, the GAS-808B goes to ON and the GAS-707B automatically switch OFF as long as the GAS-808B is pushed. If the foot switch is released from the GAS-808B, the GAS-808B goes OFF  and the GAS-707B will turn ON again. 
BOLT switch Rocker switch: If the BOLT mode rocker switch is activated, you can switch between the pedals with one foot pressure only. Only the pedal is ON, which has just been pressed. Of course, the individual pedals can also be switched ON / OFF as usual. 
• 827 Schalter switch Rocker switch: If the 827 rocker switch is activated, the signal chain of the GAS-728B NG will change. Signal chain 728B: guitar => GAS-707B NG => GAS-808B NG => Amp Signal chain 827B: guitar => GAS-808B NG => GAS-707B NG => Amp
Power supply On the rear is the socket for connecting an external power supply. It is a standard 2.1mm socket as used by (almost) all manufacturers of effects devices. All commercially available power supplies for effect devices (9V -18V DC, + = outer ring, ground = pin) can be used. The double series does not run with battery!
True bypass When the pedal s turned off, the guitar signal gets passed through to reach the amp without any loss of signal. The pedal is totally switched out of the signal path.
