Reverb Pedal Issues

[Mackguitar92]

Hey guys, I'm not sure where to post this as I am new to this forum.  I recently built sort of a clone of the MOD Kits "The Verb".  I just used the same instructions and everything but just bought my own parts and enclosure and threw an LED in it.  I used all of the exact parts that are used in the actual kit and it turned out great.

My issue is that it doesn't work at the end of my effects chain.  My chain goes guitar, wah, overdrive, danelectro cool cat, reverb, amp. For some reason when I put it after the danelectro cool cat it doesn't work.  When I turn the reverb on there's no reverb.  It works by itself and at the beginning of my chain but not at the end or after the cool cat.  Also, when I engage the wah with reverb on, when I rock the wah all the way back i get this horrible feedback thing, it sounds like the reverb just goes nuts and gets more and more intense.

If anyone here has any idea of what the problem is please let me know I would greatly appreciate it!!!  I built the pedal to the exact specs as "the verb" from MOD Kits, if I did that I don't understand how I could be having these issues.

Thanks in advance

Does it work after any other pedals like the overdrive? What if you just use gtr->overdrive->reverb?

The only 2 things I could think of are ground problems with the verb and maybe (unlikely?) DC problem on the input.

It works after the wah.  Guitar>wah>verb>amp.  It doesn't work after my overdrive though, which I built myself.  It's a valvecaster.  It's puzzling me.  It sounds beautiful by itself and after the wah.  I just can't figure out why it doesn't work after chorus or overdrive.  I wonder if it may be some way it's wired it doesn't interact with the chorus or overdrive like it should???  I'm pretty new to pedal building so I'm not a genius with all the technical aspects.

Thanks

Are you using a power supply that's being daisy chained? Just taking a guess here, but maybe there isn't enough current to run the reverb as well as the valvecaster/chorus.

I'm using a Joyo power supply.  8-9v outs and 2-18v outs.  Seems to work pretty good.  I'm totally lost.  I've double checked my wiring in all pedals, they all seem good.  It's gotta be some wierd technicality.

MOD "Verb" lacks DC-blocking to the Gate of the second FET.

Your Valvecaster is leaking DC. Fix its output cap.

Of course you could add blocking to the Verb. It really should have it. However fix the real problem (leaky ValveCaster) first.

Hey Paul thanks for the response.  Bear with me, I'm super new to pedal building so I'm not really sure what DC blocking is.  Could you quickly describe this for me and possibly how I would go about "fixing" the output cap on my valvecaster?  Also how i would go about putting DC blocking on my reverb?

Thanks
