BB-8 Footnote Amp

BB-8 Footnote Amp


Designer:
Greg

Project Category:
Guitar and Bass Speakers

Project Level:
Beginner

Project Time:
1-8 Hours

Project Cost:
Under $100

Project Description:
Small guitar amp from a recycled bread box and using an 8 inch speaker suitable for bass, electric or acoustic guitar practice.

Design Goals:
This was a first project with the Footnote amp for a gift to a family member. The goal was a small practice amp that was decently portable and fun to use. I used a different driver from the bundle since the user plays more bass guitar and I wanted him to get more use out of the gift in the end. The speaker should allow him to play bass or acoustic/electric.

Driver Selection:
294-2470

Enclosure Design:
A bread box from a second hand store that I sealed and painted. I knocked out the back panel for an open sound.

Enclosure Assembly:
No assembly needed. I screwed the bread door shut, painted the box, and carpeted the exterior.

Crossover Design:
None.

Conclusion:
Very happy with the results myself. After playing with it I will likely make another portable amp for myself as well. I like the added features of a cable tester and line input. Headphone output is something I will use when I build a second one for myself. Range of the driver is great for a small practice setup, and it gets loud enough with the speaker’s 95 dB sensitivity.
