ABDUCTOR II DELAY.

[bamslam69]

Ooh that's clever!

[bamslam69]

Completed!
The board went in easy after I swore and screamed a lot.
I actually bought one of those 1590BB2 enclosures that tayda are now selling. A few mm deeper. Soooo glad I bought it.
Effect sounds bloody amazing. Can't wait to incorporate it into some of our new songs.



Awesome effect Rob!

excellent man, nice build, love the ufo.....

Hi, I just finished my Abductor build and it's really awesome! I ordered a kit from Musikding.de. I'm not very experienced builder so there's a high possibility I did something wrong. Also the provided enclosure was horrifyingly small for this build. I did my best! Here it is:



A few drawbacks, though:
1) The volume pot is always on. I mean it's active even when the effect is off. I take this is not intended behaviour?  I did all the wirings by just looking at other builds, because almost all the links here are dead and I couldn't find much from Deadastronaut's site (just list of parts and a picture of the pcb).
2) I'm not sure if the 3rd delay is working correctly, the difference between zero level or max level in level 3 can be unnoticable or perhaps it's not working at all. I'm still getting familiar with the possibilities of this effect, so I'm not completely sure how things are supposed to work. Level 1, 2 and 4 produce a noticable, beautiful delays, except when this happens:
3) I noticed quite a bit of noise and a really low headroom to be a little irritating. It gets easily distorted while strumming chords with max guitar volume. I wonder if I did something wrong? I read this topic from start to finish, but got a little confused of what's what version of the pcb and if i should do some mods for this blue board I have? There's no company labels or any name on the pcb.

Also my first post here, happy to see this topic still so alive

Hi everybody.I got the PCB from Deadastronaut  some years ago but could not start,actually I stopped building for a long time and now I'm slowly starting back.I'm gathering parts for this build but Im going to need help with the off board wiring.My last attempt was the chasm reverb and it was a failure for some reason (obviously my fault,probably mangled the reverb brick after realizing I had gotten the wrong one and tried to make it work anyways).
Im taking my time populating this beautiful board properly a bit each day no rush but like I said I'm going to need help buttoning this one up guys.
Thanks in advance to all

PS: I see two eyes blinking that's the lFo but I found only one LFo  led on the schematic and on the PCB,where is the other one?

[bamslam69]

I'd just add a 2nd led in parallel for the LFO if you want 2.

I tried mine at practice the other night. Sounds great but with my amp distortion on it's pretty noisy. I haven't tried through the effects loop. Goes ok with my other dirt pedals though.

[duck_arse]

I'd just add a 2nd led in parallel for the LFO if you want 2.

if in parallel, you will need another current limit resistor, or the leds won't share current. and the led+CLR will need to be parallel to the other led+CLR. series leds, on the other hand, go right ahead, they will be correct, but less bright.


Colman, don't be scared to post progress photos as you build.

[Colman]

Thanks duck_arse for your help,I will post asap, right now I'm gathering parts,I have to work slow or I make mistakes.

here ya go..



the new 'red' pcbs are all fixed now. 

How come I can't see the fix for hiss, it's posted at least twice and can't see either.
Any help appreciated.

Thanks bluebunny,I've been reading all I can about the Abductor and I think this probably does not apply to my PCB,I've got the blue not the green but if I end up having to use it thanks again for your help.

[Colman]

OK finally got all the parts, pots ,box,caps etc..I really want this to work so I might need a little help as I stated before.for practice I built an orange squeezer and an expandora

Here are my PT2299s and my board:

It's easier to populate a pcb of you start with the smallest (lowest) components first. Resistors, diodes, then taller items like capacitors and IC sockets.  It makes it easier to hold the components in place when you turn the pcb over to solder them to the pads

Aside from this standard I normally put blue tape to hold them cause I hate when they slip and stick up

[Colman]

The sockets are just there not soldered.Thanks for the heads up.

Guys I have the blue PCB that has the 1M AND 1K already in the right place ,I think.
But what are those extra smaller holes that are under some of the ICs,for example there's 2 holes under IC5 and there some under the delay chips.I have started populating the board and I'm still doing Resistors but I'd like to know before I reach the sockets.
Thanks  for any help as always.

The little holes are pathways that join the front tracks to the rear on double sided boards. I'm sure they have a proper name...


Edit: apparently, they're called 'through holes' . Pretty obvious name I suppose

[Colman]

Thanks for the clarification stallik. One less thing to worry about ,I haven't done a board so complex in years  and I'm really anxious for it to come out right.

There's a discrepancy between the board label of R47/R48 on the board they are labeled R47 as 10k R48 as 22k,on the list and the schematic they are reversed,which one is right?
Thanks for helping me through this everyone.

[stallik]

Can't comment on the resistors but I believe you mentioned that you've had this board for quite a while. Just in case, take a look at post #190 on page 10 of this thread. There was an accidental short on one build of the pcb. Worth checking yours?

[Colman]

Thanks again stallik,I will check that post right now, as far as the discrepancy I think I jumped the gun,tha confusion came cause on the board there's an overprint ,the values are as stated on the scheme and the list.false alarm on my part.
Thanks again
Colman.
