Product Description

Which Mack Amp Is Right For Me? - FAQs

David Barrett Signature Amp - Atomsmasher DB-40

David Barrett is an exceptional guitarist, songwriter and arranger.  And now, he has the amp he has always wanted: the Atomsmasher DB-40!

"I've always had the best luck with simple and elegant amp designs, so that what I do with my hands on the guitar and feet on the pedals, translates best to the audience.

From the first moment I heard Mack amps at The Twelfth Fret, it was like they were designed for me, and now with the Atomsmasher DB-40, I have the perfect guitar amplifier.
My new signature Mack Atomsmasher DB-18 and DB-40 are the only guitar amps used on David Barrett Trio II."
The Atomsmasher DB-40 features dual EL34 power tubes and a Hammond output transformer specially selected just for this amp.  The Atomsmasher is voiced to meet David's exacting tone requirements.
The DB-40's tone can be simply described as "lush" - whether it is run clean or overdriven.  With 40 watts of power on board the Atomsmasher DB-40 provides lots of clean headroom for live work.  When pushed, the DB-40's overdriven and distorted tones are 3 dimensional and complex.  Like all Mack amps, the Atomsmasher DB-40 is dynamic and touch sensitive - morph from crystal clean to overdriven with your guitar volume control or a volume pedal.  And, it loves pedals!!
