I think you need to make him indoors feel guilty about something and buy you a Darkglass AO to make up for said thing.
I am really curious to try one. One thing the AΩ seems to be missing is an output level switch to allow it drive a power amp, although that would be the least important requirement. And guilt-tripping him indoors is fruitless.
I have the VT 500 head and have it set to simulate a flip top and don't hear this at all. Remind me what you're listening through?
Still the iPhone earbuds while awaiting the delivery of new enclosed Sennheisers. Yeah I know.
And yeah, I should have said 'at the moment'. It's still work in progress. Drive and Character are around 10.30, Bite and SpkrSim are both off. Maybe the Bite needs to be engaged, but I've been trying to avoid that scooped clanky generic SVT tone, wanting to get it to sound more like my amp/cab.
It does say 'VT' on the label, not 'big and dirty Bassman' -- maybe that's a clue.

I have a '75 B-15N and just had a new V pot (channel 1) and power (JJ) tubes installed - it sounds better than ever!
