Oh the price of the Accutronics Item !!!! 2 Question : 1.The delay is not paramatrable, so what is the most short/middle/long for this spring reverb ?? 2. The connector is already usable ?? i can't see, it is jack ? there is problem with the Ohm impedance ? I don't understand the shematics... so pls help <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":)"> I can't belive... a spring reverb for 20Eu (+10Eu for making a beautiful box ;) )... <A HREF="http://www.kocha.fr.st" TARGET="_top">KoCha</A>

KoCha, if you are planning to buitd your own 'stuff', then learn something (as much as you can) about shematics etc... takes time, you know. For connection with spring usually RCA-connectors are used, they sell them as related items as well: <A HREF="http://www.tubesandmore.com/new/scripts ... P-R4AB3C1B" TARGET="_blank">cables</A> Springs's parameters are predetermined by its size and what it made of ... so that's what you have - it IS fixed. Check this page again for some ideas about connection and wiring, when building your own reverb: <A HREF="http://www.angelfire.com/electronic/epe ... rings.html" TARGET="_blank">spring thing</A> here's another rack-spring built based on accutronics tanks: <A HREF="http://www.barryrudolph.com/ingear/bott ... everb.html" TARGET="_blank">RV-1 Real Reverb</A> <A HREF="http://www.demeteramps.com/proaudio/rv1.html" TARGET="_blank">RV1 at Demeter Pro Audio Site</A> respects, /Mike Zee

***** (by decay time) 1 = short (1.2 to 2 sec) 2 = medium (1.75 to 3.0 sec) 3 = long (2.75 to 4 sec) ***** here's the page to check out for some extra info on spring reverb and some specifics about accutronics reverb tanks: <A HREF="http://members.tripod.com/~roymal/" TARGET="_blank">Spring Reverb Info Page</A> <A HREF="http://members.tripod.com/~roymal/accutron.htm" TARGET="_blank">Accutronics Reverb Tanks 7-character-Part-Number explained here</A> respects, /Mike Zee

did you see <A HREF="http://www.interruptor.ch/cgi-bin/discu ... html">this thread</A> already? Dubcreator successfully connected the spring box directly to the aux send of his mackie mixer, without preamp. so some mixers seem to have enough output gain to drive a spring directly. If your mixer is not one of those you could also try to drive the spring with a normal audio amp, just make sure you only do this if the imput impedance of your spring box is in the usual range of 4 - 8 Ohm for speakers or higher. otherwise the resulting current will be too high for the amplifier. i have now tried out 5 different spring reverbs (commercial units including pre and post amp) and in summary i can say that the spring sound really differs a lot between them. so if you just take any spring and any amplifier circuit don't expect to get a particularly dubby sound out of it! i started experimenting with spring reverbs since i like the reverb sound on the dubs from king tubby's a lot. i got best results with a fisher spacexpander (a tube driven reverb from the sixties). it is likely that tubby used one of these since king jammy has <A HREF="http://niceup.com/writers/steve_barrow/ ... tf">stated in an interview</A> that they used a modified fisher reverb at tubby's: "... The reverb unit that we used to use there, it was a Fisher reverb, an' we change it up to become a King Tubby and Fisher! (laughs). ..." for me the most characteristic reverb sound from tubby's is what happened when they sent the bass drum and the rim click (i.e. from a one drop beat) together to the spring. this resulted in a echo-like wobbly reverb sound starting with a "blip" that sounds almost like a water drop falling into a tub and gives the reverb a somehow liquid/watery feel. so far i was only able to create this effect with the fisher spacexpander. i had to drive the input very hard, in fact i used an additional preamp between my auxiliary send and the input of the spacexpander. i recently recorded some samples of this.. stay tuned, i will post some wav-files here to illustrate what i mean..

ok. here are the samples: 1. a low frequency "pop" going through king tubby's spring reverb sampled from the very start of scientist's album "scientific dub" (an excellent album by the way, available on clocktower records) <A HREF="http://www.interruptor.ch/audio/scienti ... wav">click here (44khz/16 bit, 155kbyte)</A> 2. here i sent a bass drum sample through a fisher spacexpander, the high spring is muted with a piece of lace, sampled directly from the spacexpander output, no eq, no compression <A HREF="http://www.interruptor.ch/audio/spacexp ... wav">click here (44khz/16 bit, 121kbyte)</A>

hehh, Daniel, that's classic magic-drop <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":)"> gotta have a spring. btw, Daniel makes important point here, also what DC mentioned many times, keep in mind that GOOD spring reverb unit does not really mean it's good for dub. Like this RV-1 rack, it's expansive, and you may find allots of great reviews about it, but will it do any good in your dub-lab...hmmm? Well, I'm speculating here, it's just my guess, but new "improved" spring reverbs are maybe too 'clean' for creating dub-spring sound, and you may be better off with some old tank, but you'll need to do some handy-man work on it and experiment around. JUST CHECK EVERYTHING TWICE, before connecting your 'creation' directly to your mixer or any other valuable gear <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":)"> Well, you always have option experimenting with what ever digital effect-processors you've got - SAFELY, but to get the 'magic sound'... hmmm, I don't know. It's like very very hard or 'impossible', you can get some similar effect, but not like real spring. I've got something sort of interesting with digital effect processors-chain and eq/comp combination, I think the one of the best/dirty sounding verb I've got on "Crippled" track. Here link to check it: <A HREF="http://artists.mp3s.com/artist_song/2002/2002685.html" TARGET="_blank">CRIPPLED mp3</A> I was slide-sending trough effect-chain snare/kik hits group, some guitar chops here and there, also tweaking some eq in send and/or return portion in real time (well as much as could manage it with two hands <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":)">) etc... But again it's more or less just a similar vibrating sound but something is missing there... later, respects /Mike Zee

the pop happens because the low frequencies move the springs enough so that they touch.. that is where the pop comes from

I have a NEI (Neptune Electronics Inc) Spring Reverb and it works great. It also has a 4-band eq built which really helps. Before that I used just the spring tray out of Hammond, with the aux send on my Soundcraft M8 and back into the mixer. Also, I just pretty much kept the springs exposed, so I could disturb them when needed. (Just a finger flick and you'll get that classic Tubby crash). Another thing you could try is to gently brush up on the springs with something, like an small paintbrush - it can produce some interesting sounds for dub. -D
