Weber Z-Matcher and Mass 150 Attenuator Demo
To hear in stereo add &fmt=18 to the web address. It seems a shame not to use both amps even when I'm only using one, if that makes sense. So the Guild Starfire is going direct to the Vibro Champ, which feeds the Z-Matcher with 4 Ohms (technically 3.2 Ohms but close enough) and the Z-Matcher converts it to 2.6 Ohms. That goes to the Weber Mass 150 Attenuator, which can send two speaker signals in parallel, one to my Vibro Champ's 4 Ohm Weber Sig 8" Alnico Speaker, the other to my Princeton's 8 Ohm Celestion Blue 12" Alnico Speaker. After all that, what you get is the atmospheric sparkle from the Celestion and the beam-like bass of the Weber. I kept it clean since I like to use the Princeton more for overdrive. At the very end I say which speaker is on which side. It's a very expansive sound live, very enveloping.
