-It’s LOUD! This little sucker will crank, handling most gigging situations with ease. It is sometimes too loud, and I have to lower the volume. But even on 3 or 4 the amp gets some crunch on tightly cupped bends or duo-tone chords. However, it does its best work above 8 (out of 12) on the volume.
-It cuts through the mix. This amp has the character of a Champ. It is “barky” and hot. This ain’t the fat rolling tone that oozes from big saggy amps; its more horn-like, slightly muted. I have a Weber Beam blocker on the speaker to avoid beaminess, which seems to work well.
-Feedback has not been a big problem. For whatever reason, I’m usually able to crank it and just play; not wandering all over the stage looking for that one perfect spot where the feedback demons disappear.
-I get lots of compliments on the tone, not just from the audience but from blues players. They’re pretty impressed with this little amp. I think it shines for blues rock or boogie.
The Fender Pro Junior project amp has become my backup rig. I take it whenever I play, just in case. It is small, light, and reliable. I’ve jammed on it for hours with no ill effects. It sings with just a touch of delay.
Cool little amp. I think I’ll keep it.
