Bests & Worsts Reviews from Amazon

Two years ago, I bought a different headphone amp: JOYO JA-03 "Tube Drive" Sound Effect Mini Guitar Pocket Amplifier with Headphone Output. I paid $11.11 for it. I can plug it in between my bass and headphones and hear myself. I thought that was all I needed--just to hear myself for practicing. But it really sounds like crap and it was not specifically for a bass. So, last week I bought this Vox unit VOX AP2BS amPlug Bass G2 Guitar Headphone Amp which does the same thing but is made for a bass and costs almost four times as much ($39.99). Does it sound $29 better? Oh, yeah. Both units have volume, tone and gain adjustments (pots), an aux input and, of course, a headphone output. The Joyo's initial gain adjustment is a pot whereas the Vox unit has 3 discrete levels you select with a push-button. (But there is a volume dial.) The Vox unit also has a drum machine with adjustable volume, tempo and 3 different rhythms, one of which can be tweaked to be just a metronome. I didn't want the drum machine but I could see a use for it, provided we're in 4/4 time. I wish I'd bought the Vox unit two years ago; it sounds that much better. The tone is clean and rich and sounds, to me, like an expensive amp.
