A Dumble Book

If you spend any time on the Gear Page forums, you know about the legend of Alexander ("Howard") Dumble. If you don't, Dumble has created a series of almost mythical amps used by tone hounds, such as Stevie Ray Vaughan, Eric Johnson, Robben Ford, Sonny Landreth, and John Mayer. He's notoriously reclusive and builds amps only for people he deems worthy. Used Dumble amps go for around $50,000.

Author Jesse Schwarz has written a book about Dumble amps, called a Dumble Book. The book features a Dumble history, photos of Dumble amps, and interviews with Dumble and others. The cost of the book is around $300.
