Easy depth control mod for the Electro-Harmonix Small Clone EH 4600 Full-Chorus pedal

[@wearetemporary]

Just wanted to thank you for this video. Just did the depth mod on my small clone and it works marvelously.

[@davespedalsandprojects3516]

Awesome!

[@Lalairu]

Thanks for this video, I always wanted to mod my Clone... Sounds really nice but controls are too limited.

dude...this made my day!!!!!!!!!

[@johnodonnell3983]

hey i was lookinng at the schematic and everything and waas looking at some layouts where the mod is already present in the circuit, and I was thinking of using a 10k pot and removing the resistors on board and keeping the switch.. your mod however is more practical and doesnt require drilling a hole anywhere. but I just wanna know why you chose a 50k pot. is it to ensure that you cut the signal entirely without having to do math and/or does the value effect the sweep? did you use and logarithmic or linear? Does that also effect the sweep... I would think linear would give a fuller sweep right?

[@KAISERSIGMAX3]

I tried it once and swiched back to the original. Why? Because the Small Clone's depth circuit was designed to work specially in an open state to achieve a full chorus effect, considering the closed state (shallow depth) as a bonus. A maxed potentiometer is not the same as an open switch, as it grounds a little the signal and ends up reducing the depth amplitude. The result is a reduced sweep that affects the Small Clone's characteristic woosh and/or shimmer for the worst, due to the reduced depth range.

Hey do you have any knowledge of mods for the small clone that may fix this problem? Thx

[@sonclearbrahman-ar1461]

Use a no-load pot, which reverts to open circuit when you turn it down fully.

[@sunvalleylaw]

Thanks, Dave! Do you have a recommendation for where/from whom to buy a potentiometer? Would like to try it. Getting into modding pedals, and also repairing/modding old stereo gear, and this would be a good, easy practice project.

What size LED is the stock red LED on a small clone? I want to swap it out for a blue one but idk what size LED I need

[@davespedalsandprojects3516]

This pedal does not belong to me so I don't have it in my possession anymore but it looks like maybe 5mm

[@DanielS10291]

Could someone please tell me the ampage of the original switch?

[@CoenBijpost]

You could have used the switch to cut out the clean signal, making it a chorus/vibrato.

[@johnodonnell3983]

hmu please can you explain further?

[@JeremiasMarful]

I do it everything like you but now the depth is always on. Any idea about what could be wrong?

[@davespedalsandprojects3516]

Hmm sounds like something is not making connection or the potentiometer could be bad. With no connection it will be at full chorus. It should have less chorus as you turn the potentiometer to less resistance

[@johnodonnell3983]

to me removing the switch would make the depth mod always on... I would be interested in being able to keep the switch but turn the pot to adjust the depth.. however... according to the video when the pot is all the way off, then the depth switch should theoretically be "off". so it then would depend on the quality of the pot you use, cuz if your pot for watever reason doesnt fully cut of" the signal... then the depth switch is always gunna be "on".

Hi Dave. I’m going to try to do this mod. Will an alpha 16mm 50k linear work? Will it fit through the slot that the depth toggle switch was removed from? Thanks.

[@horrorheads666]

hey, how did the 16mm work out?

[@seltzer5334]

horror heads I never did it. I ended up getting rid of the small clone, and getting an mxr analog chorus.

[@betodearmas111]

wait but i wanna hear the sound! you should really test it for us, to see

[@davespedalsandprojects3516]

Sorry I dont have the pedal anymore. I should have tested it on video but I was trying to keep the video short. The only thing it changes is that you get control over the range between the high and low on the depth switch. If I ever get another one of these to mod I'll make a video of the final result.

[@betodearmas111]

im gonna give this a try! thanks!

[@davespedalsandprojects3516]

If you make a video of the result let me know and I'll post a link to your video in the description so people can see how it sounds.

[@betodearmas111]

@@davespedalsandprojects3516 man, i tried it but i fucked it up now i cant even get any sound out of the pedal... I bought a new (used) one and I'm wondering, if I send you the pedal over the mail can you do that for me? I can paypal whatever you wanna take for the mod? As well as maybe fix my broken one so I can at least get my money back if i sell it. That would be really cool...

50k. Linear or log.? Thank you.

[@davespedalsandprojects3516]

Fernando Lopez I used a linear pot

Makes fuck all difference at all...

How to make your small clone look messy with no sound difference at all..silly idea...

[@tubedisaster7586]

@@KAISERSIGMAX3 this is an interesting point. could that be fixed by adding another switch that would bypass the added pontentiometer and return it to an open state again? essentially turning the pontentiometer on and off? then maybe you get the best of both
