VOX Amplugs

I saw these on the 'net the other day but don't know how they sound with bass. I'd like to hear from anyone who has used one. Also, is the headphone jack normal 1/4" or mini 1/8" style?
Thanks

 

I got one today. The store didn't have the classic so I had to get the AC30.
I plugged it in at the end of my Boss pedal chain and it sounds really nice even through the crummy headphones I have.

 

I have the AC30 and love it. Lets me practice anywhere.

Mini 1/8" style.
