These two kinda contradictary posts are from ye olde

not? <<
I own one of each, and the short answer to the second
question is, well,
nothing really.
I don't have them in front of me, so I'm going on
memory, but the 7.6 has a
flashing LED which gives you a visual indication of
the start/end of a loop. It may also have an extra
control jack or two on
the back for setting/synchronizing delay times to
drum machines or footswitches. The rotary control on
the 8000 (which is a
detented pot like the DOD DFX94) does the same
thing as the buttons on the 7.6 for range switching.
The most important difference is internal -- the 8000
board is _much_
smaller than the 7.6, and has a big honkin' LSI chip
for
doing all of the delay functions. I believe (someone
may want to correct
me on this) it is also a 12-bit sampler/delay; the 7.6
is
definitely 8-bit.
I will now happily unsubscribe and re-enter the

I've now owned them both and agree. The 7.6 is 8 bit
and the 8000, 12 bit.
The 7.6 was noisy and distorted and as such caused me
to trade it off for
the 8000. The 7.6 might be tolerable in front of a
distortion device, but
for clean sounds, it is not very good. The 8000 sounds
quite good to me.
I'm using keyboards and I kept thinking that there
was some sort of level
problem with the 7.6. I finally concluded that that
was the way it sounded.
>The 7.6 has a hum that comes from the unit (not
>through the amp but actually inside the unit)
I experienced this as well. The hum turns out to be
coming from the power
transformer inside the unit. I had another device at
that time doing the
same thing. I was told by an electronics guy that a
smaller, cheaper
transformer like the one used here will vibrate
internally at 60 cycles. I
tried a fix with about 80% sucess. It may be of use
to someone, but of
course, don't try this if you're not comfortable with
going inside an
electronic device and I can't be responsible for
anything that may go wrong
if you try it.
1- Unplug the device and open it to access the
transformer.
2- Unbolt the transformer and pull it clear of the
unit; no need to unhook
its wiring.
3- The transformer is comprised of a metal band
wrapped around several
layers of metal plates. Bend the tabs of the bottom
of the band back and
bend the band away from the transformer body until you
can remove the band.
4- Mix up a batch of two part epoxy. Smear the epoxy
over the ends of the
metal plates. Put the band back on and bend the tabs
back into place to
secure the band. The epoxy should be all around under
the band and can
squirt out around as well.
5- Let the epoxy set.
6- Bolt the transformer back in. You can try putting a
layer of rubber
material under the mounting surface.
7- Reassemble the unit.
Basically this trys to prevent the vibration between
the plates within the
transformer and may help from a little to a lot.
>Some button presses on the 7.6 sends a small
>pop or thud to the amp.
I heard this too.
>Do you think my 7.6 could be worn out yet still
working, or did they
>just perfect the idea on the 8000?
I think your 7.6 is probably working fine. I thought
there was quite a
difference between it and the 8000.
