I've been doing a lot of practicing with my laptop and headphones lately and have decided I want something similar to an Amplug for bass for this purpose. I've previously used a Korg Pandora, a Tascam and currently a Vox Rhythmvox for bass. All worked OK but I'm sick of messing with cables and just want something that plugs directly into the guitar and then to the computer and headphones. I've tried the Amplug, but quite frankly I was not dazzled by the tone or volume for the price. Through the same headphones, it was very similar to the Rhythmvox (not that surprising), which makes up for that quite a bit by having a very good drum machine built in. For $60 plus tax, I'm inclined to just keep using the Rhythmvox and deal with the cables. As far as Amplug style headphone amps, are any of the Ebay under-20-bucks specials decent, or are there other options worth considering?
