My 35 years experience as a professional harp player has contributed to the careful planning and production of the Four-Ten and subsequently the Cruncher. I have taken this experience along with the input from thousands of players who tell me what they want from an amp. I have produced products that can be adjusted for various room sizes, mics, and the sound of the individual player.  

As evidenced by the reviews here on our site, players all over the world finally have an amp they could formerly only dream of owning. Their excitement fuels my own and inspires me to continue to push the envelope. Read on to learn what makes the Four-Ten an amp that grows with you, and is the last amp you will need to own. You’ll also see our newest amp, the Cruncher, with that low-down nasty sound.

I look forward to assisting you in your ultimate quest for TONE. And, as always, you have the Sonny Jr. personal guarantee of unparalleled customer support.
