vortex valve spring reverb

all valve amplifiers.  the vortex is designed to be used in a control room situation.   fed from an aux send and equalizer -  either outboard or ITB -  so as to tailor the signal that hits the spring . and then the vortex output should feed another eq to feed the reverb back into the mix.  with THAT set up u can really get in there and create specific characters for different purposes. you can make a vast and bassey booming atmosphere on a bass guitar or synth or vocal. or you can make a splashey little fat crack under a snare drum. or make a very fantastic-realistic room sound drum and bass section. or add a single magical distortion to a guitar.

the spring tank is mounted out of the chassis. so as  to ‘ adjust ‘ it.    place bits of soft cloth or sheepskin ontop  the springs to damp the reverb time down. then drive the spring a bit harder ..   and wow. its pretty much there into lee perry land. some smart tweaking on the send and return eqs . to clean and refine the energies and wow wow its amazing.  the kind of depth and delicious fullness of a fat refined reverb can do.  yummy experimentation.

the vortex also features a very beaut switched internal speaker.   the function is there partly to test the signal that is hitting the spring. check for too much level -  distortion -  and the signal’s balance. very useful for getting the verb sound clean of  noises or too much bottom end. or whatever. the spring is very sensitive to it.

because the speaker and amp is  EF86. EL84 A-class hi fi and pretty fat sounding for its size – u can use the  vortex as an auxillary mini monitor. it is definitely good enough to be your ‘radio sound’. the speaker has a clear valvey tone that can fill a room.  the speaker has a pretty fat bottom end.

price is 1450nz$ .   inclusive of gst (in NZ)

there’s  an iceypole’s chance in hell -  that  software emulations can build that organic authentic sound – that feels so alive – like this real electromechanical device.

grampian 636 spring reverb schematic

heres a drawing of my modified grampian 636. parts of it mite look a bit weird. without delving back into it (where i was for ages already) i can say that it works very sweet. theres several opotunities inside the circuit for gain changing. the mic stage gain control is very strange. i might be wrong about that part.goes well tho. when the gain is low (-) not much mic amp noise gets thru to the next stage.  the board is a messy one. badly planned out on variboard. my one anyway. it was a mission to draw it. all good tho.  note the power supply end.  im not absolutely sure ive drawn that right. i remember having issues when using a centre tapped supply.  i think it went ok when i had two seperate 9v supplies – stacked.  18 volts from ground to hot. and a clean 1/2 of that fed just for the tank driver.  the 2000 uf probably arent even needed if you using batteries? anyway. try some things out. have a think. youll work it out.
also note that this is a positive earth unit.  good luck.any discuss about the circuit is welcome. germanium sounds so good. its all kinds of noisey but so so juicey. wow.
