Hey guys, Is there anyway to make a guitar solo louder in a Mono or 1 track mix.

Me and some friends were jamming and we made a cool song and the only thing we had to record on was an Ipod Touch, and my guitar solo got drown out by the rythym section.

Is there any way to boost the solo using Audacity or some other online system or do we just have to re-record using tracks? Thanks for the help
Other than boosting frequencies the guitar sits in (which will likely affect rhythm guitars too, and will change the tone drastically) no there is not.
Hey, look. Sigs are back.
I would re-record the tracks. Personally, depending on the section, I will triple-track solos.
I've bought, sold, and traded more gear than I care to admit.
