i think the input and output impedance should match your pre and post-amplifiers. spring length should then not make a difference. i don't know much about analog electronics so i can't tell the details..
Hi,.... Accutronics Type 9 is the long 16" luxus- <BR>tank, used in Vermona Retroverb and other serious <BR>applications, there is 3 parallel springlines and <BR>it is made in the 3 above mentioned variants, so <BR>my assumption is that the diffrence might very well just be wirring soldered diffrent so that <BR>more or less springs inserted, I have an ebay- <BR>offer on the short-version, but don´t whant to <BR>be stucked at short-mode, hmmmmmmm
ah, now i understand the question.. but i don't know the answer. how would you want to change the delay length by soldering? cutting part of the spring away and re-attach the rest? that should result in more tension, thus higher sound and shorter reverb. <BR>does anyone produce a tunable reverb tank? i never heard of something like that altough it's an obvious idea.
I just assume that as we deal with mass-production <BR>all tre models are boiled up on same bone, just by <BR>"parralelling and serialling" the 3 lines diffrent <BR>makes the delay diffrent, so if I knew the trick I <BR>could turn a given model into one of the two other <BR> <BR>Itï¿½s a matrix, you could parralel the two first to <BR>put the last in serial etc etc all would give a diffrent delay time, so the springs should not be <BR>touched, only the internal wirring between them <BR> <BR>I talk electrically, not mechanically, but I need <BR>to know iff there is individual transducers on <BR>each spring, if not I speak nonsens :-),.... <BR> <BR>btw. you could tweak a spring-system mechannical <BR>also, string up the springs with harder tension <BR>and watch delays tighting up also, and maybe its <BR>what goes on in these type 9 series, donï¿½t know, <BR> <BR>btw I often wondered about "modulating" springs <BR>with induction/magnetism or even with a little <BR>speaker on the middle,... a vocoder,... ?????? <BR> <BR>But I have not time for these experiments grrrrr <BR> <BR>Thanks for trying to understand my obscure mind

HeHe,... Mike your not so wrong,... actually its <BR>already done, its just with a piano,. translated <BR>into a VSTe-algoritm, the name is "pianoverb" it <BR>is both usefull and overlooked, you must imagine <BR>a upright piano-frame used as a spring-tank (PSP)
HM, I have here type 9 tank, btw... <a href="http://www.mzentertainment.com/studio_a ... everb.html" target="_blank">studio page here</a> . Mine came from Mesa Boogie Nomad 45 Head. I could make some as close as my camera lets photo(s) of inside if you may need it...hmmmm? Electronically there's not much going on there ..hehe <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":-)" BORDER=0> Mechanically it's beautiful! what else? I don't know.... let me know. <BR> <BR>/Mike Zee aka Dr ZEE <BR><a href="http://www.mzentertainment.com/dub_lab2.html" target="_blank">ZDL</a>
