This is a quick watercolor sketch of my 1973 Fender Twin Reverb amplifier that has been converted to pre-CBS specifications. I used this amp professionally for many years and still keep it in my collection of instruments. I had a very small time window in which to paint this so it is more of a sketch than a painting but it was still very fun to do. The amp is painted with Rublev 18th century reproduction watercolor paint and Noodler’s Brown Ink on Arches 140# cold-pressed paper. The original piece is 7″×5″.
