a/e lover

hello a/e,
a broken and busted up sunburst washburn millenium was left at my doorstep
so i've done what any self respecting guitar head would do
i've adopted and repaired it
and it plays and sounds beautiful acoustically
but i need a little help
i'm hoping you might be able to provide any specific information
on the preamp itself as it was missing when i got the guitar
make?
model number?
picture?
features?
it still has the pickup attached and the two inputs
(1/4 " & xlr)
i would greatly appreciate any help.
please shine a light
thanks, gabriel
