Adding an AUX-In Circuit to a Hog 30 Amp?

[CarpeBasso]

Greetings all. I have a Pignose Hog 30 portable amp I enjoy playing out on the porch in the evening, etc. One problem with that cool little amp is that it doesn't come with an AUX-in jack to plug an Ipod into to play along with. I'd really like to find a schematic or kit to enable this. I'm pretty handy with a soldering gun and I'm not scared to attempt such a project, but my electronics knowledge is a little sketchy. It sounds too easy, but I know good & well there's more to it than it sounds - just installing a 1/8" jack and wiring it into the input won't work without dealing with the impedance mismatch and going stereo-to-mono. Are there any plans or kits out there that anybody knows of? I haven't found any as of yet. I'd appreciate any advice, thanks!

If it has an op-amp on the input it'd be simple to add another jack through another resistor.

Or get a bluetooth speaker for the iPod
Or, get one of these

Seems like you could just patch one of those little inexpensive 4-channel resistance mixers in-between your bass and amp.
Then connect your Ipod to 2 other channels of the mixer with a Y-cord like this: Amazon.com: Hosa CMP-153 3.5 mm TRS to Dual 1/4 inch TS Stereo Breakout Cable, 3 feet: Musical Instruments

Thanks seamonkey and anderbass for your responses! I have both of those solutions already, and I use them both in different applications. The bluetooth speaker is the one I've used in the portable environment I'm referring to. The mixer I use in my music room to mix computer out and/or bass input to some powered speakers on my desk. I just thought it would be cool to devise or locate a little circuit that would allow me to place a 1/8" jack on the Hog-30 so I could run an ipod direct to it along with my bass, without any complication or external interface. Thanks!
