Alesis JamDock Practice Center for iPad/iPhone with Monster 1/8>1/4 Adapter Works with iPhone and iPod so you can practice to specific playlists or anything in your musc library. Used a couple times, still in brand-new condition, but it's been collecting dust since I went from my 4S (30-pin interface) to gen 5 phones with the Lightning interface. If you currently run Lightning interface, you could always pick up a Lightning (male) to 30-pin (female) adapter found here (which would work great as this has an adjustable backrest for the device used - meaning, your device doesn't stand on the plug, it leans back at an angle on an adjustable backrest). Anyway, GREAT practice tool with or without an amp. Allows you to dial in the right amount of source material with your bass signal. I'll throw in a Monster 1/8" to 1/4" adapter for headphone use AND the Sennheiser HD 202 headphones which are like new as well. Also ncludes the original packaging and literature. Retails for $99.99 at all the outlets WITHOUT the extras. I'll do a deal at [DEL]$55[/DEL] $45 shipped ConUS. Thanks for looking!
