Feeding the signal into a scope through a sharp low-pass filter – cutting all above about 25Hz and letting all down to DC through – will reveal beats. Remember that PUs fall off towards DC though, and most buffers and pre-amps do too if for no other reasons that they have input and output capacitors.
What to use a scope for apart from in a lab-experiment, isn't clear to me though. Beats are easy to hear through any decent amp/speaker set-up without low-frequency cut-off built in, but following beats by eye on a scope and/or other visual indicator (frequency counter etc.) isn't all that easy.
Me; I rely on the "weaknesses" (speed/timing of level adjustments) of the BOSS LMB-3 I always have in my sound-chain, to "amplify" beats to make them more audible and easier to correct while playing. Doesn't allow me to ignore beating through any amp. |
