'Adding a Reverb Tank'

What needs to be done to add a reverb tank, say, from an organ or another guitar amp? I'm talking like with a knob to adjust the saturation and everything. How much extra circuitry is involved, and/or are there any good (relatively simple) schematics available?
Thanks,
-Chris

Checkout the Cali Dreamer - a legacy project. There is a Blackface sort of reverb in there.

I added a Princeton based circuit to a P1 eX (and trem). I have a schematic for the trem version but not the verb. If you and others are interested (say 5 or ten folks) I can spare some time to churn out another schematic - .dxf format.

A really simple way to do this, which I have done, is just add an AO-44 or other Hammond reverb amp to your output, but with its own speaker. I have a thread around here somewhere and will try to find it.

The beauty is that you can just clip the reverb parallel onto an output speaker, which acts as the reverb input. The reverb amp is high impedance, so you don't affect the sound in the "regular" speaker. The AO-44 is probably the cheapest reverb amp you can readily find. Add an 8" or other "reverb" speaker, and you are golden.

Bonus...you reverb everything in the full amp path, including power amp distortion.

Cheers,
Mick

I forgot to check up on this thread. I'll get started on a schematic this weekend.

BTW, if anyone is interested in just the tremolo for the P1 eX - it's done.

How would this schematic carry over into an Epiphone Valve Junior? I've just started modding mine and am dead keen to add a reverb tank.

Cheers, Ben.

Guys,

I have installed a new OS and am trying to recover the old schematics I prepared for the P1 eX w/Verb & Trem.

However, there is a recent post with a link to the reverb schematic I referenced, at the P1 eX forum...

[link]

IIRC is is pretty close to the Tonemonkey version, with the addition of a dwell control. The only change here is that I used a .0033 uF cap for C5 instead of the .0047 uF - simply because I didn't have a .0047 uF cap handy. It worked fine.

Oh yes. I used an Accutronics 9AB3C1B unit, and Weber reverb transformer.

Hope this helps.

'Adding a Reverb Tank - Schematics Now Available'

I pretty much finished the reverb schematic, and updated the tremolo schematic for changes I made when I installed the reverb. I opened up the amp to note the voltages, and took the opportunity to increase R18 to 820R (from 560R), and change slope resistor R11 to 56K from 100K; a tad more headroom, and the tone stack is more responsive.

I should have the schematics (two sheets) fully annotated sometime tomorrow. If anyone knows a place where .dxf files can be uploaded for others to retrieve them, let me know. Otherwise I will e-mail them when I can to folks who kindly post their email address.

For those so inclined (Zaphod - listen to your other head!), the schematics are available to whoever wants them. You'll need a viewer/editor capable of handling files in .dxf format.

And thanks for all those who helped out here (especially Phil & Iain). Sorry I took so long to get around to making this available to everyone.

I reckon we need to have an official reverb position at some point in the near future. I'm thinking that some sort of more extensible p1-type project maybe might incorporate this. Someone smart suggested a basic project with a lecture/class series that went along with it for mods. I think thats a great idea.

I realize this thread is rather old but it's the best lead I've found so far on the subject. I'm building the SE Lead version and the only thing it lacks is a reverb tank. If the schematic is still around for this I'd love a link to it or just a copy for study.

If you don't hear from JKCavitt directly, I've got copies of his original .dxf files that I could send to you. Drop me a line at my yahoo account "stephen_w_keller" and I'll pass them along.

Sorry, I did not realize there was still some interest here. I have added the schematics to my Photobucket album for this project, so everyone should be able to view, download, etc.

[link]

These are .jpgs I created from the .dxf files, so the resolution is barely adequate. If anyone knows of a site where I can upload .dxf files let me know, and I'll see about uploading them there.

Thank you,
Kelly

Thank you for the kind comments. It serves its purpose pretty well (never leaves the house). I now run a quad of Emi Ramrods in there, and leave the back open.

Hi Kelly,

I don't know of a site that natively supports .dxf files, but I'd be happy to host them on my thermionic.info site. Shoot me a note at my yahoo.com account stephen_w_keller and we can sort the details.

I'll pretty it up at some point, but this should be sufficient for now.
