GGG has a new reverb kit!

R talking about opening up the brick and modding it?

No, he is referring to the schematic posted above. R1 is the input resistor and R3 is the resistor at the Vout pin of the Belton reverb unit.

As polifemo said, I think I might like it a little better with longest delay time. But I don't think that anyone carries anything but the medium delay version of the Belton unit.

tubesandmore.com has all three versions for $15 a pop.

Really? Cool, thanks for the tip!

I´ll try to get hold of the Belton Brick with the longest decay as well.

The mods I´ve done doesn´t alter the decay time, but as one gets a fuller sounding reverb, one gets the impression of a (slightly) longer decay.

Anyone interested in moddin´the verb can start by removing R4.
Really easy and it makes a quite nice change.

Slightly O/T but there's a reverb project just been posted over at electromusic.com which uses multiple PT2399's. No schematic has appeared yet, but there's some cool soundclips and a couple of photos of the guys breadboard, which give a bit of an insight into what's going on.

Thanks for the link.
Listen briefly and it seems to be a great sounding circuit.

[Paul Marossy]

I tried removing R4 as polifemo suggested. I can't really tell much of a difference with it removed. Maybe it sounds just slightly more open, if anything. It would probably be even more noticeable if you also tweaked C2 a little bit.

I think I would like it better with the "long" delay module. I don't know that 2.5 seconds vs. 2.85 seconds is that noticeable, but I suppose it would be. That's a full 1/3 of a second longer delay...

[polifemo]

Try increasing R3/R6 a bit as well.

The thing broke again!
This time it worked fine unless i played any pedal through it. Turn on rangemaster or orange squeezer and it gets loud like a distortion pedal. Turn on the big muff and the thing goes totally quiet! I had problems with static and white noise with it after i fixed it the first time. It would start and id have to jiggle the input cord or turn it off an on again and it would function. But suddenly, again for seemingly no reason it starts acting strange again.

After desoldering the second op amp which, after probing and measuring, i assumed, was again what broke, i put in a tl082 since im outta tl072s. The thing still didnt work. And after desoldering the brick and the ic twice already, thr pcb is destroyed! Its not made like most of GGGs PCBs. After it got bad i got strange readings from the op amp that wasnt affected and from the 5v regulator which measured 7v! It looks like I have to rebuild the circuit on perf board. Desolder the surface mount regulator and use it on perf board. I cant afford another kit.

What the heck is wrong with my unit?!? Please trust me, ive checked connections, wires, resistor and cap values and orientations, solder bridges, and its not a metal box problem. Its plastic.

Only thing is i just measured the voltage from the adapter i used for it, it was putting out 12v instead of 9 like it says! In fact All my adapters that say 9v put out 12 except for the one spot. Which is unusably noisy, even with my commercial pedals.

I need my reverb back! That was all i had and it sounds like crap without an atmosphere! I just spent 4 or more hours trying to fix this! Im not gunna be able to sleep. This is the only DIY pedal i really paid for. I ordered the kit sans enclosure, and its given methe most problems! Strange unseeable voodoo problems! 

[El Heisenberg]

I dont NEED to use that particular 5v surface mount regulator, do I? Can i just lift one from radioshack? Breaboarding and building this on pas-per-hole is gunna be a pain in the $:$

That enclosure looks too small to have a Belton reverb brick in it. Or they have a very clever and efficiently designed PCB in it...

[ppatchmods]

it can't be the belton because you can adjust the dwell/decay. being able to adjust the decay makes that pedal sound like the old digitech xp400 i used to have. it had some sweet plate reverb sounds but it was a tone sucker!

Hmm... I wonder how they accomplished that then?

Keep in mind that marketing is about perception... It may not 'technically' change reverb decay but you may be able to come up with a way to give the "effect"of a decay control.

Yeah, but I still can't see how they can stuff all those things into that size enclosure. 

[ppatchmods]

That's true Brian! If you could figure out how to dial back the mix without affecting the decay that would be cool...still, there is no need for a decay knob at that point(with the belton brick).

I used the Spin FV-1 and wrote a custom reverb algorithm for it.

Hello friends 
First of all let apologize to mr. Jd sleep cause he's a really. Cool and nice guy and the hirmida engineer dude
who designed the generalguitargadgets.com D-verb with belton Btdr 1h reverb . I kinda pirated
the layout he posted in the ggg site and etch a pcb for myself , I just couldn't buy the kit at this time
plus I had the belton btdr1h brick longest version  in hand so I said, "why not" ?
Well the circuit works fine and it sounds clean!!!  , is just that the reverb isn't very very long as I thought it would be considering the
longest decay version of the brick. I heard that it can get very wild 

My question is : is there any mods that you guys know that I can do to increase the
level of the reverb so that I can use the full potential of the belton unit 
I would really like to hear this reverb sound a bit longer I used all the components in the layout
with exception of the BAT 46 diode , I just couldn't find it here.
Help me out here please !!!!     IMG_1084.JPG
