That would be the lack of compression
Nope, that
would be hard ;) I was thinking of having a second, hard
clipping alg. and bringing that in for high ampltudes.
oh yes, please keep on bringing them on. i put in a music-dsp shaper (archive credits patrice
tarrabia
and bram) after the inverter, and with some eq (hp basically)
before entering the first valve, it sounds surprisingly good.
especially with the bridge pickup, the neck pickup is still a
bit muddy.
OK, time for a quick lesson - whats the difference between the pickups? My
bass (cheapish active 4 string) has two sets, a single wide one and a pair
slightly offset (they say duncan on them FWIW). There is a knob that, I
think crossfades between them.
It doesn't.
there are no time domain effects, and it doesn't adapt to
amplitude - just a static trasfer function. It could be an interrelation
with the two valves, but I dont think so...
after some more tinkering, i guess you're right. for some
reason, guitar notes die away very quickly with this setup. there are three issues for me with the current setup:
* it doesn't noticeably prolong sustain.
* the attack phase is 'flat', compared to the ringing
of the real thing.
OK... could this be a property of the cliping? Or is it always there?
* the sound gets muddy and faint when you turn down
the
volume at the instrument, instead of keeping loudness and
reducing distortion.
This is another compression effect I suspect.
i suppose that these could all be improved by applying
the
right sort of compression. i've done fairly quick tests with
applying gain before the first valve, and with the new
compressor from your set. the gain fails miserably, and i
I think that the compression effect in a guitar amp is much faster than
what you get from a general purpose compressor. I think it is more like a
slow acting saturation. My Valve rectifier plugin (valve_rect) was an
attempt to capture that, but I expect it needs adjusting, or rewriting.
