A good choice when building a Tweed Deluxe (5E3) and going for an original appearance and tone.

by Michael -

I bought this speaker with my 5e3 tweed deluxe kit that I also purchased from MojoTone. I finished the amp build and installed the speaker on 1/15/2023. From that day it took about 10, 30 minute plays to get the speaker broken in. At first it sounded shrill but now it sounds just like what you’d expect from an original 5e3 circuit with an original Jensen p12r. The bass and warmth are awesome, clear highs and the speaker sounds good when overdriven. I am very happy with this speaker.
