I practice through a mixer and headphones nowadays, lot more sociable, and I get a better tone.
Going back 30 odd years, I had my own house, 2 up 2 down terrace, lived on my own. I had 2 1x18 W bins that I used as my rig together with a 300 watt Peavey head. One day thought it would be a good idea to pipe the hi fi through it. It was that loud that not only did my neighbour come round, but my next door but one as well. Never did it again.
My current neighbour likes music, every bloody weekend, got woke up at 2.00am last Saturday, it was 3.30am when they turned it off and went to bed. It's getting where me and the wife can't enjoy a weekend night in in peace now.
I do get on with the neighbour, but it's getting to the stage where I'm going to have a word. I have a Hartke Kilo and Ashdown 1x15 and 4x10 cabs, so I suppose I could re-run the pipe the hi fi through it gig. But that's not what it's all about is it.
