I often have a problem with volume when I switch between finger play style or slap/popping or tapping. Say the volume is fine when playing with finger style but then going to slap/pop it's too loud. Or I'm playing finger style but then switching to tapping, it's too soft. I'm not really sure the best way to handle this. Do I get a compressor so that everything is just level, do I get a volume pedal (like a wah pedal) or do I get something like the MXR Micro Amp that can boost to a certain amount?
