Machine gun studio's base rate is $50/hour for tracking and mixing. However, for all but the smallest projects i prefer to work out a package deal for all tracking and mixing ahead of time rather than watch the clock for the whole session. This often results in an hourly rate less than my base rate. Occasionally I've let bands pay in installments over the course of the project. Whatever your budget i can find a way to work with you. Please feel free to contact me for a quote.
