Roland JX-3P issue?

Post by synthboi » Fri Jun 05, 2015 9:34 pm

Hello, I'm new to the website, but I obtained a JX-3P a while back and found out that the sensitivity slider is really, really jumpy. I mean, REALLY jumpy. This has made the synth's tweakability very sucky, and purchasing a PG-200 (or even the clone) is just way too expensive, considering I purchased the synth itself for $175. I've tried using contact cleaner, but it still is really jumpy. Is there another way of fixing it easily?

That slider is probably just shot. If you're handy with a soldering iron, it shouldn't be too hard to replace.

This is the replacement part you need:

Syntaur is out, but there's the specs.

The PG-200 sells these days for like $350... So a JX/PG combo for $525 isn't too shabby. ;)

The clone is even cheaper. It's about $240 on Juno http://www.juno.co.uk/products/mode-mac ... 553430-01/, plus shipping, so you're in for less than $300.

I can also confirm that Juno's shipping and service from the UK to the US is superb and fast. They often have things in stock that are hard to get in the US.

It's best to take out the slider and take it apart then clean it...should be ok..

Re: Roland JX-3P issue? - jumpy slider

Post by Tekhed66 » Sun Jun 07, 2015 2:27 am

I have just fixed up my JD-800 which is famous for its very dodgy and jumpy sliders...

I opened her up and used a can of compressed air to remove most of the dust and fluff and then used Deoxit F5 for faders to give it a good clean.... spray it on and work the slider back and forth for a bit and flush out any excess with more air.... the synth is perfect now and a DIY job saved me at least $300 in servicing fees.

I used to own a JX3P many years ago and it's a great synth ... it should be fairly simple to access the slider and give it a clean.

Not sure where you live but hopefully Deoxit or something similar is available.

If you open up the case, use the chance to give the case a good inspection... flush out the c**p that builds up under the keys and change the battery!!!

good luck
