June-60 Follow-Up: Internal Trim Pots

Donald Jordan tears down the June-60 chorus to investigate the effect of the internal trim pots.
For your (and your pedal's) safety, do not attempt this unless you are comfortable working with electronics!

I’d like to mention that the pedal does not have to be disassembled to get at the trim pots. The underside of the trim pots are accessible through the bottom of the board and can be adjusted with a mini flathead screwdriver. You may need a flashlight to see them through the small holes.

[@Bloom_Music]

Good info, thanks for the heads up.

[@HazeAnderson]

@@Bloom_Music thanks for tearing down anyway!

[@graphenemusic5922]

do I still need to take that glue off the post if I trim those from the back of the board?! thank you, best regards!

[@joerobot32]

@@graphenemusic5922 probably, but its not really strong stuff, you might be able to move the trim pot without removing the glue. I did it anyway.

[@PingPong85]

Props to you for actually following up on my request! Thanks!

[@Bloom_Music]

No problem, I just wish the results could have been more successful!

[@melvinhawkins4567]

I was honestly hoping that the trimmers would have more of an effect, but the I setting definitely sounds better after you tweaked it. Massive thanks for taking the time and effort to do this.

[@TriangleWaveRecords]

Just snatched this pedal knowing full well it sounded nothing like the Juno chorus haha. With your settings, it sounds more like the CS-80 chorus, ironically enough.

[@matthijsblomjous3671]

I like what you did with it. sure, it doesn't sound like the juno chorus but I still like the overall sound.

[@MusicMindset]

Great sounding pedal! It also looks cool, so it is a win win here, haha. Great video man!

[@McN4styFilth]

Thanks for the follow up!

[@mongchacha]

Thanks for doing this! I chuckled when you said you didn’t hear anything when you first started messing around.

[@Digiphex]

Thanks for doing this. The pedal definitely needs an LFO speed and depth on the front. But I guess the original circuit from the Juno didn't have it so this was an attempt at a true clone.

[@agincourtdb]

Thanks for doing this, I will be attempting to mod mine in a bit!

[@kiosko33hz]

Hi and thanks for the vid ! I've read that if you replace the 1024 stage BBD of the TC electronic version by a 256 stage BBD you get closer. But then, my question would be : Would that affect the internal clock?

[@redmodpedals9100]

do you have a click noise synced with the lfo ?

[@UBERLADEN69]

Needs to be on an aux or f/x loop. Then the dynamic interplay of mono dry & stereo wet can be blended with control. Thanks for the instruction.

[@ranzee]

Great vid. Be interested to know what electronic value these trim pots are. Perhaps they can be replaced with a smaller value and make them into a full potentiometer mod for mounting on the outside of the case. I suspect there maybe a few other tricks we could do to this also.

[@matthijsblomjous3671]

I think the pedal would really, really benefit from mods

[@josephwright5921]

Yes. My thoughts exactly.

[@josephwright5921]

Someone could make some bucks modding these

[@olivellamodular]

I opened up mine and both trimmers say 103, aka 10k potentiometers. Also, in my unit when you turn them CCW the sound gets duller and less bright but maintaining the modulation depth, so there's tone tweaking potential there as well

[@matiasmoulin2126]

to get this straight: do the 2 trimmers not affect the speed and depth??? So should we actually better not mess with them but change caps instead? A clarification would be much appreciated since we all wanna know how to improve the pedal, I guess :-)

[@profile1251]

So basically just crank both trim pots clockwise?

[@f115Recs]

Thanks for doing this. Interesting to see that it's not all SMD!

[@xy9394]

I wish someone would take apart a TC Drip and try to solve the volume loss problem

[@danielbarry5547]

Yea, if I have to do all of this then I might have to stick with my voodu valve preamp chorus lmao

[@davedunnonline]

is this even outputting stereo? It sounds mono from here

[@michaelpowell7120]

Hilarious. Thanks

[@Grapebotdd]

Which vst is this?

[@losleo]

its hardly sounds stereo

[@JT-bp2oc]

Hey bro maybe next time use a guitar or something? Hard to hear the depth of the chorus when you’re using a synth, which already has some type of effect, making it hard to hear the chorus.

[@agincourtdb]

There's no effect on the synth, he says it's clean. Maybe you're hearing the synth's amp eg (the settings that control the shape of the amplitude of each note)?

[@gnatiu]

I think what you've done here is a nice attempt though useless because of the non-musical information you are sending through the device. We van hear a change in the effect speed, okay. But first: the tone you use is really nothing but a futuristic sounding signal. I wish you'd also tried some guitar or usual musically connected CHORDS, a phrase... This is only giving an idea in relation to the speed, that is it.

[@pyrotas]

When you play so much guitar that you completely ignore the rest of us also digging other instruments such as - for instance - synths. Like, hey, the Juno 106! I find this video quite informative and musical - for sound shaping is a part of music as much as any other.

[@kiosko33hz]

@@pyrotas Hahahhahaha ! You nailed him good.

[@kiosko33hz]

@@pyrotas ..By the way we love futuristic sound signals:)

[@UBERLADEN69]

The entire point is that this is a circuit expressly made for enriching a single oscillator synth. Like sonic lipstick. This is an exploration to determine its potential for fidelity to the original. There's a thousand other chorus pedals for guitar(d)s j/k
