Back in the early eel ® days, I used to warm up before practice by smashing my left hand lightly with a 32 ounce, redwood handle, "plumb"® brand, framing hammer, it added exponentially to the
sustain on my fuzz box. It was Way-Gnarly-Way ! !
Well sir, pretty soon, every one was refering to me
by the nickname "Broken Hand" ®
you know, like Eric "Slo Hand"® Clapton
( though I not sure that's a registered nickname
And has the name stuck ! !
Boy has it ever ! !
