I just had this idea for for a possible cheap and lightweight, Wireless (Bluetooth) IEM for my guitar.

Balanced speaker emulated output of Blackstar amp > Bluetooth audio transmitter > Bluetooth earbuds

Does anyone know what kind of latency there would be with current bluetooth tech?

Cheers.

bluetooth definitly lags bro,i purchased the platronics 906 backbeat bluetooth headphones in hopes of using them for practicing but there is indeed some lag,perhaps what you suggested could work but you would be hearing yourself a quarter to half second after what you just played,
