Hey everyone, thank you for the great feedback!

I'm working on another batch of Amps and I've already sold a few to people who asked about them.
I'm doing it a little different this time. I have red, blue, and silver in addition to the black case I had before. I also have black or blue headphone jacks. And finally, I have a couple of different volume knob options. I have the black plastic knobs with white, red or blue stripes and I have the metal knobs in matte aluminum with black stripes.
Right now I have 7 amps. Two are assembled with black headphones jacks, the rest could go either blue or black.
I have 2 black, 3 red, 1 silver, and 2 blue cases.

Obviously I have limited numbers of each, so I may run out of a certain color. It's first come, first served.
For this round I'm asking $140 shipped in the US with batteries and a power supply and $140 + shipping for international orders with batteries but no power supply.
If you want the metal knob, it's an extra $5.

Here's some photos of the different options:

Here's the Red case with a knob with a red stripe and black jacks next to the blue and silver cases.

Here's a closer shot of the red amp.

It almost looks black in the pic, but its definitely very silver with a white (almost gray) stripe on the knob.

Here's 2 shots of the metal knob on my own amp from the first batch with a black case. Its very matte.
 
I now have front panels in. I have the clear ones and I also have bamboo ones. They are $6 each plus $2 shipping if you buy less than 3. Check out the pictures of the bamboo panels below.
Go ahead and paypal me at aerohoff at gmail when you're ready.
