The Porta Studio 424.  The first multi-track
recorder I ever used. It was very easy to use due
to it's ability to record the 4 tracks on normal
cassette tape. It didn’t take me long to start
taping over
some of my favorite music tapes
because I needed new media to record new
tracks on.
The porta studio that my friend let me have
had already seen years of use as well as
damage. At times the power would just cut out all
together and I’d have to wake up
Each day and wonder if I could use it or not.  But
it was free, so I did not complain : )
When it did work, it was perfect for
me. I was just starting out with
recording and this was just what I
needed. It had a low & high band
eq, separate volume knobs for
each track preview. It had the
ability for 1 FX send, but at that
time I had no idea what that was,
so I never used it.
As soon as my friend showed me how to
bounce the 4 tracks to 1 track I was off
and running...................
And had allot more tape hiss as a result.
As time went on, one day a friend and I
opened it up, and thinking we found it's
main problem with the power, fixed the
wiring.
It never worked again after that.  But for
those days it definitely proved itself
Worthy and was definitely one of the
most important learning tools I ever had.
