I'M ONLY GETTING CLEAN OUTPUT!!!!
|
I don't have a whole lot of depth or usable speed. I have tried 2 of my 3 PT2339 chips. I think there were some posts about this, now to find them.
I built mine with 100K pots in BOTH positions and I am in agreement with you. When I first fired it up, I was kinda disappointed. It did not have much Depth at all and the Speed was something to be desired. Then I talked to another forumite and he told me that this is a fantastic Chorus to use for playing single note phrases or leads... HE was right! This is not going to sound like a CE-2 or Small Clone if that is what you are looking for. But it really fattens up and puts a great "voicing" on single note playing!  |

Man, don't give up on vero! I am so fond of it...the quickest way to build for me...Glad you made it with the LA.
I have plenty of boards and I'll likely use them. In all honesty, part of the problem was the iron I was using. Pulled an old one out and much better results. This was also my first time with vero. I'll build a few simpler circuits and get the hang of it. It just seems a bit limiting on layout when trying to keep a small footprint. |

I'm just using it to thicken my sound on my solo acoustic rig and from the clips I've heard, it's exactly what I'm looking for. In all fairness, I think my speed pot may be audio taper (had it in inventory) and that may be the problem. I'm ordering parts for inventory and I'll check that first. |

Never mind my last post....user error. I will toss in however that I give a thumbs down to the Delay mod. Unless you do not have a delay pedal and want some slapback. Otherwise, if you want a Chorus pedal stick to the basic layout.
I'd say definitely otherwise, it's definitely not a delay replacement! Just give it a tiny bit of delay and it widens the sound considerably. I put a 5k pot in and that's loads of delay for this purpose - I usually have it only cracked open about 20% or so. |

Really?! Let me firmly disagree on this one...my layouts prove it. |

IT"S.... A.... LIIIIIIVE!! Rick had me check R7, and it was way off (used my good DMM this time). Replaced it and my voltages were in line, but still no chorus. As a last resort, I cleaned/touched up all my solder joints and now it works! I still want to get more effect at 12 o'clock with both pots, but I'm so pysched that I have chorus.
Think I'll invest in a better soldering station. Circuit Specialists has a real nice one for $30. Thanks to Rick, Pigyboy, Government Lackey, and Chris for all your help.

I am newbie to troubleshooting and Im not sure how to measure the voltages across the ICs Got a DMM (multimeter)? Hook up the black probe to ground, then use the red probe to check the voltage of each pin of both chips.

I have a problem with the PT2399 it sens probably sensitive to statics; some of the IC's I tried do not make the effect; and others make the effect in some level; some high and others a bit low!!!!! I've lucky with the first it's loud; and I prove a second one no effect; others less or more effect!!!!! that would be happends!!!! do anybody have this problems?  |

In Perú there are no standar cases for FX you must make yours!!!!! I make the cases for tree dimencions: 10x12x5 cm; 8x12x5cm and 15x12x5cm These are the standar for me!!!!! when I finaly made the pedal I post the interior and the made of these mod for your pleasure!!!!! OK I forgot to put the value of this pot an here is the new layout; please a look ofr another error!!! tnaks a lot!:  I may be wrong, but I see no sense in those long traces leading to Speed pot. And not only them. But well, I'm not an expert, and I didn't create a single layout myself. Just wanted to share thoughts. Hi, is there a pcb for this layout with all the pots, I'd like to make this version, I hope their is one, thanks for any help with this |
