if the cellar is below ground level the only real issue is the upper floor ...a false ceiling supported from the side walls ( avoid any contact with the floor to avoid sound conduction through it )....bass is the biggest problem is like water it can get anywhere
baton the walls...and if you're on a budget use as mentioned egg boxes ( free ) use the softer materials
mentioned between them and the wall ( this will deaden/refract the sound and give you a good recording environment ) make a small booth to put round your amp and sound treat that.. stand it on thick foam to absorb any sound being conducted to the floor (and the room acting as a boom box)..
no matter how much you soundproof though you will always get leakage...so be realistic with your sound levels...bass is the achilles heel so turn it down a couple of notches
whatever you use for the ' skin ' if hard material paint it matt you dont want shiney surfaces
cellar studios are brilliant ...but leave room for the corner bar and get the missus a louder tele or put her and it in the shed ( not forgetting the mobile )
