Hacked Chinese reverb

[Teledog]

So, bought a Grand "Fender reverb re-issue" reverb unit from Ali (supposedly free shipping)
Seller asked for more $$ for shipping, and I did so.
Arrived "not working". (got a $225 refund off a ~$600 investment)
The 6V6 plate/cathode had no connections, after adding/wiring the connections, ..it was intermittent (there was a fine strand of wire between some tube pins, may have been me, or?)
Anyway, decided to hack the "already beater" unit, added another tank (a MOD long, 3 spring-long decay) Original was a medium, 2 spring-medium decay.
Added a 3PDT switch, (for switching between tanks),  took out the dangling participle power cord & foot switch wires, added a PEM & jack, a "real" 1W tone pot, chassis nuts, etc..
Still a "beater" but it sounds great!

Right so they use, or used to use, springs in amps for reverb. Someday I'll have to look up a circuit for that, and other effects. I play guitar once and a while, years ago I had a nice Marshall amp with springs for reverb. I can't guess how they use them in the circuits, to make reverb.

Very simple. The spring is driven at one end with something like a speaker coil and monitored at the other end with a pickup. The sound travels through the spring with a delay.

So sad, money spent off-shore for another non-working piece of shit.

Basically it's a mechanical delay with plenty of resonances as a bonus! If you want something freaky (well .. I was freaked-out by it ) check-out Uncle Doug on youtube dabbling with an "oil can" reverb.

And then there's the plate reverb;

Wouldn't mind making one.. if I hade more real estate..

Here's how to (ab)use a stand-alone spring reverb.. notice the foot smashing/tilting of the unit for the crash sound

And yes, the Jazzmaster & Gretsch sound great with it :-)
