will this spring reverb work as an aux (impedance/RCA)

Post by spacef »

Hi all,

lookingto get on of those cheap spring reverb from ali express

I've tested it at a friend who use it just to "pick" the spring and make old school reverb sounds (like kicking on a guit amp with spring reverb). he did not use it as an aux effect. it sounds like it should be in that use case.

I wondered if the impedance etc would be ok to use an an aux effect with send return connected to an A16 or a patch bay, once i get jack-to-rca cables. or will it blow away ?
Thanks

Specs:
input
Impédance: 600 Ohm

tank like that requires a driver circuit.

what is a "driver circuit"? a preamp or attenuator ? (the tank is supposed to work "as is" on a DJ mixtable with aux sends)

One of these might do the trick.

For me the link above doesn‘t work, so I can‘t comment on that item.
Spring tanks need a driving amp for the initial coil (basically a single channel headphone amp) and a preamp/buffer for the receiving coil. A sensitive line input may do, but this depends on model.

A cheap (not too bulky) alternative:
the Roland Cube 20 or 40 from early 80s has a very good spring tank. It‘s an extremely clean guitar amp and you can track via the headphone output (only 1 channel needed of course). They usually go for 50-100€.
Randy Rhoads used exactly that amp as a backstage warm-up for it‘s precision in tone.

Scary808's link was to a lunchbox (or eurorack? didn't look long) format balanced i/o spring reverb.

thanks guys. I know better now.

Well I don't want to get a guitar amp (I play approximately 1 or two riffs per year now, lol), but the 2nd hand way is a good idea. Thanks for the references (Roland Cubes). The lunchbox looks like expensive studio stuff (API 500 format? but it doesn't look like it is being made anymore, there are other racks and desktop boxes at the resellers' links (re-ampers).

May be I'll get a tank anyway and make a sample bank of the springs being plucked and kicked and tortured (the output works fine at line levels, no need for anything).... far from being a priority though. Pure gadget :-)

If it was only for guitar, I'm the kind of guy who would go the guitar pedal way , ampless, (surfy bear sounds awesome, but there are cheaper stuff that are ok).

for Aux effects / DAW (samples, recordings) I guess I will continue to count on software (the Aegis Spirit Reverb gave me convincing, results on reggae guitar samples (dub style FX), and it is cheap in price and resources too so one can load many and not even bother with aux sends, not like arturia's etc which sounds really dirty and takes ridiculous amount of CPU and generates weird artifacts making it unuseable, or other manufacturers who do "studio springs" that do not have the sound I'm looking for)...

Hi Mehdi... I just „inserted“ the Cube 40 into the my current io-setup by a Digidesign 882/20 as send/return.
Send into the anp’s guitar input, a stereo splitter into the headphone out (to silence the speaker), 1 line back into the 882/20, reverb dial full on.
The amp is rather crisp by nature, but hiss is controllable by gain and eq .

Sounds as expected with FM/PD synths of steep attack and short decays, imho not so great with longer decays or „warm“ basses/brass.
Spring-twitch is present, but the tank has a fairly short decay... nice on guitar but may not fit more ambience oriented effects. If you‘re interested in an audio example, tell me what kind of sound...
