Speaker - Jensen® MOD®, 8", MOD8-20, 20W
The Mod 8-20 is a 8" ferrite speaker with 20 watts of power. Straightforward tone with smooth highs and more predominant lows. It responds to overdrive distortion with a mellow fuzz overdrive.
The MOD® Speakers lineup is a collaborative effort with MOD® Electronics that provides musicians with a classic sounding speaker voicing that doesn't shy away from new technologies and modern advancements. Unbound from the restraints of producing an authentic reissue, Jensen® and MOD® have developed a new series of speakers that carefully blends the clarity of the vintage Americans with the forward, driving tone of their vintage British counterparts. The result is an extremely versatile sound that sits well in any mix, be it classic rock, blues, jazz, or contemporary genres.
Guitarist Description: Straightforward tone with smooth highs and more predominant lows. Responds to overdrive distortion with a mellow fuzz overdrive.
Bassist Description: Bright
- Lows: Loose/Fat
- Mids: Firm
- Highs: Smooth
- Overdrive: Smooth

Speaker tone is subjective, so while some might agree with that statement, we can't guarantee you will have the same experience. We do feel, however, that these are great speakers in a number of applications.
