Hey there, I'm Ryan Printup. I live in Buffalo, NY and work as an Embedded Software Engineer at Fender, building the firmware inside digital guitar amplifiers and effects. I've been writing code and playing guitar since I was 12. Outside of work, I write music, try new recipes, and run to burn off the results.

Digital guitar amps with 50 amp and effect models, 100 presets, a color display, and Bluetooth audio. |
A five-button remote for presets, effects, tap tempo, and the tuner on Mustang LTX amps. |

A multi-effects guitar workstation with a 7-inch touchscreen. |
A pocket-sized amp for playing guitar through headphones. |
I play guitar, mandolin, and bass with three groups. See where I'm playing next on my shows page.
