We don't need to dispute each others expertise. I suspect most guitarists own stomp boxes. Some of them use an electronic bypass, so the OP simply could use a stomp box to compare the sound of adjusted impedance with non adjusted impedance. Period. My forecast is that if it should make a difference, than neither to the good, nor to the bad, it always sounds less good, than when using a guitar pre-amp connected to the mixer, let alone a guitar amp with speaker recorded with a mic. This means the OP just needs different EQ settings, in the end the sound with or without adjusted impedance for several usages isn't as good as the sound when using just a guitar pre-amp or much better an amp with speaker. Your advice was "Get a DI box." My advice shortened to what's important in the context of this dispute was, that a stomp box most guitarists own, for this purpose does the same job as a DI box. So why recommending to pay for additional gear that gains absolutely nothing? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
