So I just received the Avatar SB112 Cab to join my Ashdown 300H head today and I played for a while this afternoon. I noticed a few things that were out of the ordinary. First, the needle on the VU display doesn't seem to move much and almost always stays to the extreme left. If I want to zero the needle I would have to turn the level knob to the max. I don't want to do this for a few reasons though The other thing is that the EQ and Subharmonics don't do much at all. I mean, I have to turn the knobs on the EQ quite far to the right to hear a substantial change in pitch except for the Bass knob. When I play through a BOSS ODB3 pedal I can easily notice the EQ change though. I'm just wondering how high I should have the input level because the sound is very nice despite these few little discrepencies. The EQ works well enough for the amount I would use it anyway but I just need to know where to have the input level knob because I don't want to blow something in a brand new head. Please let me know more about Ashdown MAG 300H fine tunings. Thanks.
