can you drop a hint about how you came up with the valve
algorithm?
probably it should be quicker to react. it's not easy to sort
out though, i still haven't got around to get the pre-eq right.
four (or more, if more list members care) ears are certainly
better at sorting this out than my biased two. i've put three
files for testing setups on http://quitte.de:
/power-chord.flac -- a low power chord (root, fifth and eighth)
you know this one from the guys that want to be really bad.
the more distortion the better. should really give a wall
of sound, without any auto-wah at all.
/arpeggio.flac -- a fast-paced arpeggio on an unwound string,
this one should sound familiar from ego-maniac solo work.
should sound clear and sharp, with lots of distortion.
/riff.flac -- excerpt from a jazz melody. i'm particularly
interested in getting this to sound right. unlike the first
two, this was done on the neck pickup, so it's a good
candidate for testing for muddyness. should, but needn't go
with little distortion, but ringing attacks.
there's no eq or other fx on these recordings.

try not to move the left hand too much in the beginning, rather
use all fingers and all strings.
the neck, usually placed exactly where the second

an over-sized fretboard, has far less dominant harmonics than
Cheers, I really should learn how to play the thing sometime. always. i
think it might be because a real valve amp sort of
'spreads the excess power' by turning the wave into almost
square at this point, where the guitar signal carries a lot of
energy. more of a limiter effect, right?
Maybe, or maybe the valve reacts to transients in some way - that could
partly be a side effect of the HP filter, emphasised by some valve effect
we haven't modelled yet. i just tried
it before the first valve and it does help a
good deal to have a better attack [in fact i got carried
away strumming a funk pattern, a first time for playing the
guitar through the box], but i'm slowly running out of cpu.
OK, the CPU problems can be improved. Looking at the rectifier I haven't
really optimised it at all. Do you have a feel for whether it should be
faster or slower?
