SONICAKE USB Chargable Portable Pocket Guitar Headphone Amp

So silly me, I thought that because I was an adult that owned my own home and could play my guitar and bass through my regular amps whenever I wanted. Turns out that when the wife is cranky and I am working on the same riff for an hour straight I am in-fact not allowed to use my big amps. So since I have been really happy with the pedals I have purchased from Sonicake I decided to check out their headphone amp for use when the wife says no to the big amps. I have tested the headphone amp in a Peavey G-90, Predator, Patriot, and Generation EXP as well as a Peavey Fury Bass, and a Cort Curbow Retro 4 (active) Bass. This little amp worked out well in all of them. The reverb is nicely there, It is not overpowering, but not anemic sounding either. The volume gets loud enough through headphones, as well as plugged into a small set of non-powered headphone jack speakers. The gain gives you a little punch but stops short of distortion. The amp arrived with a full charge, and through several hours of testing the battery lights still have not moved from the 4 full bars. There is some slight hum, which I found was almost completely reduced by turning the amp up and then using the volume knob on the guitar instead. The hum was more noticeable with single coil pickups but that is to be expected. The construction is plastic, and the switches and knobs are small, but it's a $30 headphone amp, it's not a half stack. Be nice to your gear and don't come at it like Godzilla and it should be plenty durable. It will have a space in my gear for testing craigslist guitar purchases, for going camping, and for keeping the wife happy when she says I'm being too loud. :( There is only one negative that i found and that was that it would not fit into my wife's 2006 lefty MIM Strat. The angle of the jack plate in that guitar seemed to start putting upward pressure on the amp before it fully seated. There was however no problem using it in my 1994 Peavey Predator which is a strat type guitar. I do not have a another Fender Strat to test so I can not say if it is a Fender issue or if it is an issue only related to her particular guitar. In any case if you have been told to quiet down based on my experience I think this is a good option and I would buy it again.
