Let's see, usually through my Mackie 1202 mixer into
headphones (Sennheiser HD445) - have neighbors, you know!
Or from the mixer to a Jolida power amp and Infinity tower
speakers (both from my hi-fi; both about 8-9 years old...). Or from
the mixer to my bass guitar amp - Hughes and Kettner
BassBase 400 into a Euphonics Audio enclosure (a 3 way set
up). Or into an Alembic F1X to a Mesa Boogie 20/20 into the EA.
Or into another bass amp, an Acoustic Image Clarus... As you
can guess, I also play bass guitar...
