Looking for a simple BTDR-3H circuit to build

Hey guys!

I'm looking for a simple circuit to use for a Accutronics BTDR-3H. The datasheet circuit seems pretty simple, is there a way I could apply this for guitar? Also, how would I go about adding additional controls for it?

Thanks!

Define simple?

The most popular build seems to be the Rub-a-Dub deluxe here:

Yeah, I've seen that one. Basically I'm looking for the lowest parts count, and lots of tweak-ability. Also, I want it to have stereo capabilities. Thanks!

I've just boxed up a stereo reverb, which uses the BTDR-3.
It is not simpler than the Rub-a-Dub.

What do you want to tweak?
Do you want stereo in, or just pseudo stereo out?
Do you want this to work with a guitar, keyboard, theremin...?

I'd love to take a look at your circuit! I would like there to be possibility for a tone knob, mix knob, and feedback. Not really sure what else exactly. Stereo ins and outs; is there a way that I could plug in mono and come out true stereo? And have it still work with two inputs? Guitar primarily, although keyboard functionality would be sweet!

Is it just me or these are doubtful questions for a business pedal builder?

Just coming here to learn, I am no expert and have plenty of room to grow. I am not trying to hide that fact, and there would be no reason to. I have never built a reverb pedal before, and was wanting to get some advice from other people who have built them before. It doesn't make sense to have a problem with me asking questions, just because I own a business. I am 17 years old. I am not a genius, just a kid with a dream to build pedals. It hasn't been easy, but I put in the work regardless. I come here to learn, not to be criticized on my abilities. I am sure that anyone here on this forum has more knowledge than me, and that's why I am here.

I will be posting my design soon - just have to tidy up  the schematic and record some audio.

It has stereo in and out (although the inputs are summed into the reverb brick) and has a tone control.
I don't see any point in adding additional feedback to the BTDR-3 as this is what the depth control does.

Alright, can't wait to see it! I need to buy a reverb brick so I can start messing around with it, I just wanted to get an example of how you might do it. Thanks! That makes sense, I was thinking of the older BTDR-2 bricks that had different controls

I'm not criticizing your abilities, I just think you're looking for a schematic to copy, maybe swap a cap or resistor, then selling it.
And feel like it's misleading your customers and abusing of our forum...

People willing to learn usually build something before they ask for tips or suggestions.
Why don't tweaking or modifying any BTDR3 schematic free on the net (GGG or BYOC) and asking for tips about YOUR mods?

I totally understand that, and am not in any way trying to disturb the peace or misuse this forum. I would never want to mislead any of my customers (the few that there are) in any way. I am definitely not looking for a schematic to copy and sell, I am actually trying to get together a lot of different schematics to see what different methods everyone has for building pedals; in other words, to learn.

Not trying to pick a fight here at all, I just feel that these things need to be addressed. Not exactly sure what that last part was (maybe a typo) but I do not want a fight or argument.
