I think it will, delay lines need not be a integer multiple of 1::samp
either, at least not for a interpolating delay (which we have).
I'm not 100% sure what will happen if the delay length becomes less then a
samp and you still want to use feedback. Feedback loops in ChucK Ugens will
always add a single sample delay. You may have to fake this be putting a few
delays in series.
Delaylines aren't especially hard on the CPU, the main cost is probably the
interpolation but I can't imagine why that would take more for extremely
short delays. It'd be a different issue if you wanted delaylines
considderably shorter then a samp with feedback in one Ugen. Clearly that
would create a need to interpolate multiple times per sample and place some
rather large demands on the quality of the interpolation.
BTW, I'm rather surprised that this technique was used in a guitar amp; I
thought the sweetspot was relatively small? Wouldn't that be unpractical for
