Whiplash Audio Elite Micro Line out dock (low-profile 30-pin to mini-plug cable) INCLUDES SHIPPING!
Will Ship To: Anywhere
As pictured. Connect your iPhone 4S or lower or iPod (any that use the 30-pin connector) to an amp with one of the smallest docks available.
Costs $140 new from Whiplash Audio. I'm selling it for $90 INCLUDING SHIPPING AND PAYPAL.
It hasn't seen heavy use and apart from the letting having rubbed off slightly (from the dock being stored in pocked in a bag) it is in good condition.
