cool reverb apart from switch spdt 'pop' issue

[chromesphere]

Ok, I just got a long brick in the mail for my tenebrion reverb, but after seeing the demos for this I think I'm building one of these.

Would anyone be interested if I had a few boards fabbed up?  It might take me a bit to get it all right in eagle, but once that is done, OSH park gets me boards pretty quickly.

R O Tiree offers the PCB's for purchase already.

+1 :  mikes boards are the nuts. 1590b sized too..

[aballen]

Are his boards etched or fabbed? 

I can etch one myself... but I really prefer the plated through holes on a fabbed board.

Does anyone here have a belton brick they would like to sell me?  Antique Electronics supply has @#$%ed me over again. When I ordered it, it CLEARLY said in green letters "In Stock"

But I got my package today and there was only a switch that I ordered. I called them and they told me it was on back order till mid July. ALL OF MY RAGE!   This happened last time I ordered from them. I'm done messing with these people....they have a 100% failure rate.  I suggest if any of you order from them to call in the order.

They are not plated through, but they are soldermasked.

Nevermind... I talked with the supplier and changed it to vertical mount (which I can make work) and I got them to send me a free shirt after a little fuss. First time they messed up it was ok,these things happen, but the second time the exact same thing happened and that's not ok. So I got a little compensation

A quick questions for those of you that have the dry level control. If you turn the dry down completely does the wet signal thats left reach unity? If it doesn't, is there a way to correct it so that it does?

[jmaguire]

I realised earlier today that I had not implemented the Oscillation mod. I've just now finished that.

Here are the new v1.6 files:

How much for 2 of these PCBs including shipping to Ireland please?

sorry haven't had a chance to try the dry mod out yet, but i do have a brick on order to try it out , i will probably breadboard it again and test it .

eventually...

I just finished wiring mine and now comes the debugging. I'm not getting any dry signal. When I turn the dry pot up all i get is the faintest barely audible distorted dry signal that almost sounds like white noise. In the morning I'll try putting pin 1 of the dry pot to ground instead of virtual ground and see if that makes any difference.


Edit    I couldn't wait till morning. I tried lug one to ground and got the same thing.    Any suggestions? Has anyone built it with the dry mod yet?

[haveyouseenhim]

Anybody?

[deadastronaut]

haven't tried it yet mike...

[jmasciswannabe]

Anybody?

I adapted this dry control to a similar circuit using the above described method and it worked fine, except that when I took out all the dry there was a volume drop with just the wet. That's why I was wondering if anyone had completed it on this circuit and the result.

Re: Wet/Dry Mix:

First, keep in mind that I have no idea what the hell I'm talking about.

I looked at Merlin's Equinox reverb and he has the back end arranged like this:



A couple of differences are that he is using a TL072, and he doesn't have a JFET on the output from the reverb chip.  I'm thinking that there shouldn't be any major differences between the outputs of the bricks vs PT2399.

It may not work for this application, but it looks like an easy mod to try.

Hey guys, I just did up a bom/component list so I can refer quicker (making a few) - am I blind or is there no R10?

[pastiche]

Guessing it might have dropped out from an earlier schem

Sorry, double/ triple post. Getting used to tapatalk...

Go with the schem and layout I sent you in my email. There is no R10 in there. I suppose it was inevitable that differences would creep in between deadastronaut's original diagram and the various versions of my layout as suggestions from forum members were incorporated.

@self destroyer:

so you verified my pcb layout.  this one? CME reverb.

[jeromeplank]

any know if it would be possible to add an effects loop on this verb? i'd like to play around with adding stuff to the wet signal a bit. maybe get into some modulated reverb territory.
