"Overdrive Special 038 This is another export model that was sent to Applied Acoustics in Germany. Some of them were only shipped as an amp chassis. The Cabinet for most of these, 20 - 25 amplifiers were not Dumble made.
Overdrive Special 034 is a 50 watt model. It has 6L6 power tubes and is fitted with a JBL K120 speaker. This amplifier has a beautifully clean and chimey tone and the unmistakable Dumble singing overdrive. This is a very clean Overdrive Special and except for the Applied Acoustics made cabinet, untouched." -Jesse Schwarz. A Dumble Book, pp. 113/114
Jesse Schwarz mistakenly confused the serial number which is in fact "038" and not "034" as shown in his book.
The previous owner purchased this amp from a private client in Germany around 2004/2005. He told us "Some of the filter caps have been replaced and the speaker has been changed for a 12 inch Electro-Voice BRO/12. It is one of a run of 15 - 20 Dumble Amps where Howard Dumble shipped 15 - 20 chassis' to a German Dealer in Bochum - 'Applied Acoustics' who had the cabinets made."
Joe Bonamassa did not own this amp, but had it loaned to him where he used it on his album "Driving Towards The Daylight".
"Joe's newest album titled “Driving Towards The Daylight” hits stores shelves on May 22nd. Joe’s lucky 13th album, was recorded with Kevin 'Caveman' Shirley. This was their seventh collaboration over the past six years. Recorded at Studio At The Palms in Las Vegas, NV, The Village Recorder in Los Angeles, CA, and The Cave in Malibu, CA, Driving Towards The Daylight is a true blues rock album, that puts a rock twist on traditional blues songs." -Driving Towards The Daylight Review
