[LAU] checking passive input frequencies on non Hi-Z connection

[Ralf Mardorf]

My apologies, a last PS:

If I play clean single coil bottleneck (a short metal bottleneck, not a
long bottleneck made of glass) via the mixing console's mic pre-amps,
I'm using a "BOSS Compressor Sustainer CS-3" stomp box. Sustain is very
important for all kinds of guitar playing, not only when using a slowly
played bottleneck with an e.guitar, in a "Ry Cooder Paris, Texas"
style (IIRC it's played on an acoustic resonator guitar, I only
want to describe the style). I would use the same to play tappings
(different, but leant on a Stanley Jordan style). The "BOSS Compressor
Sustainer CS-3" is still useful when playing a good tube guitar amp,
but it isn't that much needed. It's not a simple compressor. It also
does amplify at some level. The chain of guitar sound is very, very
long. Used wood, used guitar design, used cable length, input impedance,
response characteristic of the amp and speaker, used strings ... not
only sustain, but sustain and warmth are much related to this chain.
The saturation of a guitar amp (as well as of old elCheapo consumer
tube gear, not of "good" and expensive old tube gear) is completely
different to other audio gear.
