I dabble a bit in electronics.
Actually it was my main field of study in tech school, but after 6 months of looking at the
same small workbench I decided I wasn't built to do that for the rest of my life.
I'm also a guitar abuser.

When I guy at work told me that his kid had an old junk amp for sale for $25 I jumped on it!
I was a little shocked to see it was a 1979 Fender Deluxe Reverb.
The tubes were all junk, the capacitors were leaking and the cabinet was in pretty rough shape.
First came the electronics.

All new tubes, capacitors and diodes brought it back to life.
A new handle, grill cloth and few touch ups to the vinyl finished it up.
OK, it was a total of $450 in parts, countless hours of driving to gather the parts, and
about 6 months of work, but....

You can't beat the sound of an old tube amp.
Even when that old bald guy if beating up the Epiphone Les Paul. ;)
