Both units are in very good, like-new condition.
This is a great little preamp. Very utilitarian. I have used it on DB, EBG and acoustic guitar with nice success. Half rack space. Comes with everything including the original packaging. $150 shipped. Paypal preferred.
All the specifics are available here:

I also have a "matching" compressor. The bluemax. The bluemax has some nice usable presets. It works really well for most all compressor applications. Comes with everything including the original packaging. $100 shipped.

If, by chance, you want to buy both, I will throw in the rack mount that allows you to mount both 1/2 space units in a single rack space. Or, I'll sell it to the first who wishes at $25 shipped.
Please email for any additional questions.
