Just got myself one of the new Ampeg SVP CL preamps and believe it or not I'm finding it hard to get a balanced tone out of it. Sure, it has plenty of mids and grind but getting some AUDIBLE bass on there isn't as easy as turning the bass knob.. at least not at home with an Ashdown mini 4x8. The Ashdown EVOII has no problem. I think it is due to the bass frequency set at 20Hz which is really low. I've tried the ultra low but that also seems to suck 20db of mid out @ 600Hz which is a too much. So for now, it's back to the Alembic. Why is the Ampeg voiced like this? Anyone else have issues getting some audible bass on there? Why 20Hz???
