Members photon9 Posted May 11, 2010 Members Share Posted May 11, 2010 I've been thinking about putting one in on my Booger V22. I've seen some pictures of homemade ones and it doesn't look like it would be too hard to pull off building one from scratch. Any resources you could point me too (schematics, guides, etc). How hard would it be to scrap (or bypass) the digital one on the Booger and put a spring one in place of it, still using the dial as control? Any advice is much appreciated. Thanks.

Members WRGKMC Posted May 11, 2010 Members Share Posted May 11, 2010 You mean Bugera V-22 There are kits and diagrams for DIT reverbs. Putting it in your effects loop might work if you modify them for the correct impediance. Replacing a digital reverb and overriding the intergrated circuit may have complications. It would require an expert to decypher the schematic of the amp and insert the spring signals. It would make a mess of the circuit and drilling new holes for the controlls. The existing ones are likely PC mounted and cutting the traces to rewire would cause a bastardizing of the existing pads. Chances are the Signals would all be the wrong voltages for splicing in a home made job as well. If you want you can dig up a schematic for the amp and post it I can verify how difficult it would be. You may have to buy the schematic if the manufacturer permits it. Manufacturers try to hide their designs from piarates wanting to do exactly what you're wanting to do. They dont have to give unauthorised personel access to their designs nor identify all the components if they do. Even when they do, they have their own part numbers stamped on components complicating their designs. My best advice would be to just put it in the effects loop if the amp has one. You can google up kits for reverbs easy enough, build and mount it in a separate box. Link to comment Share on other sites More sharing options...

Especially to put in a preamp tube to power it etc. I think you're right about putting it in the effects loop. Do you know any sites for building a spring reverb petal. That would be fun and have the same effect. Thanks again.Photon p.s. I affectionately refer to Bugeras as boogers lol. Link to comment Share on other sites More sharing options...
Members mrbrown49 Posted May 11, 2010 Members Share Posted May 11, 2010 I saw a kit a while back to build an outboard spring verb similar to the old fender version. I'll try to find it. About your pedal question, spring verb tanks are too large for a pedal. Look at building a head unit. EDIT: Just found this but I have no idea if it's any good. Looks like it's the driver and recovery circuits are solid state though but if you've never built anything like this before that may be a good thing.

Members mrbrown49 Posted May 11, 2010 Members Share Posted May 11, 2010 Cool! Here's another option. This kit will turn a valve jr head into a stand alone reverb unit. Sounds like a pretty cool deal. Those heads are cheap, especially used, and the kit price isn't so bad either. Link to comment Share on other sites More sharing options...
Members cobberdig Posted May 13, 2010 Members Share Posted May 13, 2010 just a thought slightly off topic but maybe of interest, if you ever come across a dead organ, they are a free for all for lots cool stuff that can be modified for guitar use -spring reverb units, swell pedals, loudspeakers, leslie units etc etc. I used to see heaps of them in hard rubbish and not even blink (not that much into organs) until one day i opened one up and realised it was a goldmine.

Looks like it's the driver and recovery circuits are solid state though but if you've never built anything like this before that may be a good thing. I'm thinking it would be cool to build a spring reverb unit mounted in the ample space in the bottom of the amp put in the effects loop. Dimensions would be roughly 1.5'x3"x3" to fit. I don't know if there is a way to power a pre-amp tube using batteries but that would be cool as opposed to having to plug in for power. That is the simplest idea I can think of that seems possible. Also having a footswitch to run to the front with true-bypass. I don't really know much about this stuff but having wired 3 or 4 guitars I'd like to tackle something a little more challenging. But not so much as having to completely rewire the amp like my original idea seems to entail. I'm not opposed using a solid state driver and recovery actually. Probably more robust at least. I'll keep looking for schematics and try to settle on something. I'm not really too interested in prefab. If I were to do that I might as well just get a holy grail... which I'm considering. I want to build something lol. It's been too long since I've done any modding or upgrades. I'd like a project and this seems like it could be a cool project if I can get my grubby hands on the info I need. Thanks again! Link to comment Share on other sites More sharing options...

Members Belva Posted May 24, 2010 Members Share Posted May 24, 2010 I'm watching closely. I'd like to dump the unused aux channel in my re-purposed p.a. head and add a 'verb. Link to comment Share on other sites More sharing options...
