Plugging in a Standard P Bass I fiddled with the amp a bit before cranking it up so I could hear it at full volume. This things definitely gets loud, unfortunately that does not mean that it sounds good. Personally I thought it sounded horrible at high volumes. There was a lot of distortion going on, even without the built in Overdrive engaged. I didn’t tweak on the controls much while at the high volume, but I doubt that I could of dialed in a usable tone. Once turned down to a more respectable level I tried various tone settings but just could not really come up with anything I liked. This amp seemingly has a lot of tone controls with it’s Semi-Parametric EQ, Tone Presets, Overdrive and Compression Circuits, so perhaps if I had spent some more time with it I could of found something I liked. In truth, I’m more of a less is better kind of guy, especially when it comes to built in effects. While having on-board effects might be convenient to some, I don’t like the idea, and feel that it’s just one more path your signal has to travel through before getting to the speaker, even if you don’t use them.
On the surface the Fender Rumble 350 seems to have a lot going for it, I just didn’t care for the tone. I love Fender Basses and have played through a few Fender Bass Amps over the years, but have yet to find a Fender amp that has the tone I am looking for. At 350 watts the Rumble certainly has a lot power, yet interestingly enough it does not have an output for an additional speaker cabinet. Moreover, at almost 70 pounds, this thing is a beast! Sure is comes with removable casters but those don’t help you lift the thing up when putting it in the back of your car. I know there is a lot of love for these Fender Rumble amps, but I’m just not feeling it.
