Greetings All, I made a pilrimage to the Good Will store today to drop off some household items and of course I had to browse while I was there. I noticed a small powered Yamaha Subwoofer from a cheapo surroud sound system for $10. I decided it might be a good size for a small bedroom practise amp. Having gotten it home and tried it out I can't say it's going to replace an "official" amp but it just may work out for a fairly low volume alternative to wearing headphones. It seems to reproduce the notes on my 4 string down to low E ok. With no horn it's not a slappers practise amp! Anyone else tried something like this?
