Palmer Pocket Amp Bass

I bought it mainly because of the headphone output and the “sweepable” middle frequencies and I am not dissapointed!
The clean channel sounds amazing with both my active and passive basses. The controls are super responsive and give you a lot of possibilities, and the knobs feels sturdy. The FX insert is a great idea to save space and the other features like speaker emulation and headphones output sound really good.
I deducted points because the Overdrive and Fuzz channels are too mild in my opinion. In order to get a good crunchy sound out of them, you need to crank the Drive almost all the way up (I go all the way!) and use the Normal input (not the -12dB) even if your bass is active. It only really crunches when the input signal peaks. Otherwise, it would be the ultimate affordable portable amp. In those conditions, it's a really good fuzz pedal, too!
On the other hand, with the OD and Fuzz you can use the Blend at 100% wet signal and still won't lose a lot of bottom end, which is a nice plus - as is the auxiliary input, for practicing.
The manual could be much better. For example, I am still not quite sure I understand what exactly the Saturate knob does - mostly, I just go as high as right before my tone starts to sound funny, for the compression. All in all, it takes some work to master all the dials.
I still haven't, but I would easily use it for recording of on stage (the option to use the DI pre or post EQ is also a great feature!). The metal housing and the foot switch feel they can take some stomping.
The other day I used it to practice guitar with headphones (7-stringer with a heavy distortion pedal) and it sounded pretty good, too! =D

So it's rather cheap, has lots of controls and inputs and outputs. And it's tiny. I like that I can take it wherever I take my bass, just plug into it and play.
- Bypass is not really a bypass, it's amplifying the signal, too. It creates nice clean full tone. Sounds better than plugging the bass directly into the Hi-Z input of a mixer;
- EQ controls affect the overdriven sound. If you set Blend to 0, EQ will be flat;
- Gain+Blend+EQ controls make for lots of combinations of settings. I find it rather difficult to set a good tone. Sometimes the best tone I can get is the Bypass (Green LED);
- I can't really hear what Saturation does. According to the manual, it's a mild compression.
- Aux in and headphone out are great for practice in the night;
All in all, it's a great combination of features.

I guess if you pay more and buy a bigger box, you'll get better tone. But you won't be able to carry it in your pocket.

Other than the saturation knob that doesn't do ANYTHING (maybe ive got a defect), Its a nice box.
Esentially its a Di box, but also with an option to EQ your sound, a pretty nice but not very audible cabinet simulator and an OK overdrive.

Another cool thing is you can actually just plug your bass guitar into it and start playing.(with headphones) all you need is 9v .

on the negative, the Fuzz isn't very useful for recordings its too harsh. some buttons feel a little bit "weak" and are a pain to clean because they are very small.

I Ended up selling mine and moved to a simpler D.I box.
