Interruptor: How do you like the rx-100 compared to your fostex reverb? I'm looking around for a good sounding spring reverb and considering both of these. Furman seems to have made some good ones too. <BR> <BR>-Looter
Thanks for that information on the Furman. <BR> <BR>My friend used to have a Fisher reverb in the back of his Pontiac- gave up the "stereophonic concertized" thang..sure it did... Motown and soul sounded great thru that, especially when you went over railroad tracks.. <BR>jp
I'd love to have a tube powered spring reverb like the Fisher but my transistor fruman rv-1 does the job pretty well. It has a great sweepable midrange EQ, treble control, and dry/wet mix knobs. <BR> <BR>The first thing i usually end up doing when I get an old piece of gear is opening it up and looking at the insides. Inside the furman, the spring unit itself is suspended by small springs and there's a small pcb that the pots are mounted on in the front of the enclosure. <BR> <BR>I'm pretty happy with the sound now but it is noisy and I'm thinking about replacing the capacitors with fresh ones. I've heard old, worn out electrolytic capacitors are a big cause of hum and noise in vintage gear. I'm also thinking about shielding the power transformer, if anybody has any advice about noise in spring reverbs maybe they can help. <BR> <BR>The rv-1 has a 3-spring unit and i am going to try this damping technique with the cotton. I have the problem that if i move the reverb around or hit it even lightly it makes loud pops like something is shorting, i dunno. I want to get the splash sound that only smacking a spring reverb will give you. There is a review of the rv-1 on harmony central where someone says they give theirs a good smack and it makes wonderful noises. So, i'm looking for loose connections, and thinking about insulating the floating spring unit from the bottom of the enclosure. <BR> <BR>So again, any words of wisdom on this stuff would be greatly appreciated. <BR> <BR>Peace, <BR>Looter
Indeed spring reverbs create a lot of noise. I managed to get the noise to an acceptable level with the following methods, the spring reverb is still the noisiest device in my setup though.. <BR> <BR>- make sure you drive the reverb with full load: <BR>open the aux send on the desk and the input level of the reverb as far as possible without getting too much distortion (ok this one is obvious - but still worth mentioning) <BR> <BR>- use low and high pass to filter away all frequencies which are not needed for your reverb signal <BR> <BR>- listen closely to the noise. If you have notable supply humm you can eliminate it with notch filters (50Hz or whatever depending of your AC-current frequency + harmonics: 100Hz, 200Hz,..) <BR>This is easy to do if you use a software based mixer with freely configurable filters. <BR> <BR>For even better results replacing the capacitors may be a good option. Looter: Please let us now about the results if you actally do this! <BR> <BR>peace The Interruptor
hey dub heads! <BR> <BR>re: spring reverbs and noise <BR> <BR>you should not drive a spring reverb straight from a mixing console. a preamp stage is required, and after the reverb a gain stage. otherwise you will get a lot of noise. also the sound will be MUCH better <BR> <BR>look for schematics on the web, u can build this with a few op-amps
good point about the preamp.. all reverb units we discussed above do have built-in preamps though. <BR>even with a preamp the noise level is considerably higher than with a digital reverb unit. If one loves the spring sound it's just about finding ways to live with this.
Hey David, yes i think it's a good price and choice! <BR> <BR>And as interruptor have say, software filter are the best way to cut noise on reverb. I use a 50hz on the mastering. I have just send to my software filter a sample of the sound of the reverb with no reverb. <BR> <BR>See you. <BR> <BR>Jah Bless, <BR>KoCha / <A HREF="http://www.almighty-dub.com" TARGET="_top">Almighty-dub</A>.
Hi David, <BR> <BR>I listed 3 reasons above why the rx-100 is not a good device for use in a dub mixing setup. <BR>The 4th point mentioned above was sound. This is up to personal taste of course. I personally prefer the sound of a fostex 3180 or even better a spacexpander. <BR>I recommend to try out the device for a weekend if possible before spending the money.
<FONT COLOR="ff0000">[note: i corrected the model name from "fostex 8890" <BR>which was wrong to "fostex 3180" and added two pics, <BR>cheers, interruptor]</FONT> <BR> <BR>fostex 3180: <BR> <BR><IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... 03/515.jpg" ALT="fostex3180"> <BR> <BR>- parallel springs: you can open the box and <BR> mute some of the springs with a piece of cotton <BR> or so and get a grittier sound. <BR> <BR>- true stereo: separate springs for left and <BR> right channel. <BR> <BR>- all springs are tuned high for more high <BR> frequency response (brilliance). Cannot <BR> compete with digital delays in terms <BR> of brilliance but this is not what you buy a <BR> spring reverb for <IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... /happy.gif" ALT=":)"> <BR> <BR> <BR>boss rx-100: <BR> <BR><IMG SRC="http://www.interruptor.ch/cgi-bin/discu ... 03/516.jpg" ALT="bossrx100"> <BR> <BR>- Has a "folded delay line". This means 3 springs <BR> are put together in a z-like shape. Thus <BR> successfully eliminating the typical spring <BR> wobblyness. (A pitty because this is what <BR> i like most about spring reverbs) <BR> <BR>- you cannot mute a single spring to get a <BR> grainier sound without muting the whole <BR> delay line. <BR> <BR>- mono: has stereo ins and outs but will just <BR> mix a mono delay sound with your stereo <BR> input signal <BR> <BR>- no dry signal control: you will always have <BR> a mixture of input signal and reverb on the <BR> output. <BR> <BR> <BR>==> As you can imagine i prefer the fostex 3180. <BR> <BR>Another good choice is a Vestafire Dual reverb <BR>which is similar as a 3180 but featues also <BR>some springs which are tuned low. (low frequency <BR>response) It's especially these low tuned <BR>springs which give you a wobbly sound. <BR> <BR>In an interview King Jammy mentioned that they used <BR>a modified "Fisher" reverb at King Tubby's studio. <BR>The only Fisher reverb i found on the net is <BR>the so called "Spacexpander" a tube driven reverb <BR>from the sixties. It would be great to try out <BR>one of these.. (They are sold at ebay for around <BR>100 US$ and more - quite pricey, especially for <BR>me as I would need an additional voltage <BR>transformer for 220V and get it shipped to <BR>Europe for around 50US$) <BR><FONT COLOR="ff0000">[update: i own a spacexpander now, it really <BR>comes closest to the classic tubby sound :-) ]</FONT> <BR> <BR>peace <BR>The Interruptor
If anyone is interested in a BOSS RX-100 spring reverb, I am selling one on E-bay. <BR>Just search for BOSS RX-100. <BR>I've had it from new c1984/85 and it has all original packing and the manual. <BR>It works fine.
I have a furman rev 1 and am quite happy with it despite the noise. I like the EQ on it. Smack this one and you'll get nasty clicks/pops. What you can do is take the spring itself out and place it somewhere else. Just solderiron some connectors and wire it up. <BR>replacing capacitors won't eliminate the noise. With good and big enough capacitors in the power supply will eliminate hum. <BR> <BR>DC
