Ahhh, the lowly Musicmaster Bass amp. This was just an inexpensive student model bass amp, it was not intended to be much, and it really wasn't much of a bass amp. Too little power, the tone really wasn't right for bass, and the speaker was too cheap and didn't deliver the goods. But as a lot of folks now know, there's a great guitar amp hiding inside. Ditch the POS speaker and replace it with something decent for guitar and the amp comes alive. There are a couple of mods you can do to these amps to really wake them up. Out of a small collection of silver face Fender amps the Musicmaster Bass may be my favorite. Though that's tough to say, as my favorite amp seems to change with each one I play; as I'm playing it, it becomes my favorite. But the MMBass is good enough to hold its own with the best of them, it just does it in its own way, and at a lot lower volume, which is a good thing at times. I don't gig with one, but I sure do a lot of practicing with one.

 I don't like hacking up vintage Fender amps, but in this case, we're not doing anything non-reversible, should you ever want to put it back to stock for collect-ability's sake. Just hang on to all the old parts and reverse the mods in that case. But if you want a player and not a showroom piece, you're going to love these mods.
