Testimonial from Ice – Shop Supervisor & Tone Inspector
“Hi, I’m Ice. I may not have opposable thumbs, but I do have an ear for tone and a nose for quality wood.
Every day I patrol the shop, sniffing out bad solder joints and ensuring every guitar smells like success (and maybe a little beef jerky).
Mike built me a custom dog-sized Telecaster once. I couldn’t play it... but I licked it. It passed inspection.
So if you're wondering whether to buy from Carparelli Guitars, here's my advice: Sit. Stay. Buy it. 5 paws out of 5.
Now please excuse me while I nap in a pile of tonewood.”
