Ampeg SGT-DI question.

[dave_bass5]

Ive bene looking at this preamp but getting conflicting advice about the SVT/B-15 switch. 

A mate has one and says he never uses the Grit side, but can hear a difference between the two modes. Reviews say this switch only affects the Grit side. 

Can anyone confirm what is going on with this switch please.

I've not had one for a while, but used to use it a lot. As I recall, the knob on the far left is the volume and compression, which only applies to the signal when you activate the preamp switch, and the knob on the far right is the volume and grit (distortion), that only applies to the signal when you activate the SGT switch (which gives you the B-15 tube tone). When the SGT switch is off, the volume/grit knob does nothing to the signal.

The B15/SVT only affects the Grit side. Part of the reason I ditched it is because of having to always hit no try footswitch we just to turn the B15 sound on. That and the stupidly high treble frequency (10kHz if I recall correctly).

Thanks for the replies. Im really only asking if the SVT/B-15 switch does anything with the SGT switch off, but good to get some real world impressions.
