I might be able to get one EMG variable mid control for almost nothing. I would swap it for the tone pot in my bass like it shows on the diagram from EMG. But I dont know if it would give me more flexibility over my tone, to have a mid control instead of a Tone? I know it would be best to also have a Bass/Treble control on top of that but I dont have money for that. I only want to go throught the hassle of installing it in if I know it will help my tone. Thanks in advance.
