Thank you. I have the exact same issue. Seems to be a common fault. Gonna fix mine up too. I have been waiting approximately 5-6 years for a video like yours, as I am hopeless at fixing things, especially electronics, and there weren't any dealing with that model, and neither my local guitar store nor the manual was any help either. Your video helped me tremendously.

I have the same amplifier, and the same problem, if someone needs to buy the selector, it's an SR1712F-0108, I just bought it new, although disassembling it can surely be fixed as you did, thank you very much for the help

[@brentatkinson73401]

I have two of the amps and need one of the switches so if you don't mind advising me where to order the part...🙏

[@brentatkinson73401]

Ok l ordered the new switch so going to attempt the operation tonight...or tomorrow night..(

[@ReedHarrison]

Where do I order it from. I just bought one used and same pot is dead

[@brentatkinson73401]

Ok if anyone is asking l got this and other parts at Mouser Electronics out of Texas ⚡

[@ReedHarrison]

I have the cube street model with two speakers in it. Does mine take the same switch.? It's an 8 position

[@evgeniydragondog]

Thanks for info!

[@BrewerShettles]

Good video - interesting how Roland uses cheap parts inside

[@SwapnenduKar]

Hello there, wonderful video. I have a problem with uneven volume swell when increased just a bit. How to solve? Will a contact cleaner work?

[@Stahodad]

Thanks i have a micro cube with same issue. I was thinking man these amps all sound the same! 😮

[@georgegleek]

Hi You said the plastic part of that switch you bought was a bit short, did RS sell an alternative with a bit more plastic on it, or is it not necessary? Thanks

[@mowogfpv7582]

The part I linked was the closest match from rs at the time of the video. The shaft is slightly short but acceptable. A closer match may be available depending on where you are in the world and when you order.

[@BSites]

Thank you! This fixed my Cube30X.

[@mowogfpv7582]

Awesome! That's what it's all about 👍

[@Plectrum41]

Wow very impressive!

[@Orange_Lemon]

Thank you.

[@sulejanos6886]

Wow. Thanks a lot. My input jack fall into the amp after the plastic locking thing broke into pieces. I tried all the large screws but I did'nt think I should unscrew the top two at the handle. And even if I would unscrew that, I wouldn't dare to apply that force I needed to move the switchboard.

[@ajiprasetio88]

All the problems are same. Thanks for sharing

[@Issra87]

I have one for repair here. It turns on but all lights go up and no sound. The analog session appears to be working but it is the digital parts that worry me...

[@mowogfpv7582]

I'm not sure if that could be the selector switch or not. I guess the switch has two failure states. It can short and connect two or more models simultaneously or it can fail open? I never tested to see how it behaved in either case. You could roll the selector switch around and see if anything changes. ...but there are so many other things it could be. Probably it's a different problem. I would start by taking the boards out and inspecting them. Checking the connectors are all seated. Looking for blown caps or anything else scorched looking. That sort of thing. Sorry I am not enough of a cube expert to help more.

[@espacoipiranga]

I think it must be rust. It is all rusted and corroded inside. Needs a deep cleaning for start.

[@totyteles]

Hi nice video, i got an 80x and the effects dont turn off is there a way to disconect them? I dont use them . The flanger effect is alway on cant use the amp. Can you help?

[@mowogfpv7582]

Sorry I am not familiar with that problem. Does the knob still change the effect type or amount? What happens if you try to turn the effect off with a footswitch?

[@totyteles]

@@mowogfpv7582 não it remains on flanger. Im goin to try with a foot switch. Thank you

[@juliansw3110]

Went through the same failed, frustrating repair attempt. Any chance you have the stock/part number for the rotary switch? There's a few on the RS site. Cheers

[@mowogfpv7582]

RS Stock No.:123-9618 Good luck!

[@georgegleek]

Yup. Mine was fine, dropped it off my bed onto the floor and boom now I only got the clean channel . So I can buy that switch from Roland themselves?

[@mowogfpv7582]

Probably not. And definitely not cheaply. I bought a switch from a large UK seller that was similar enough to work. The best place to buy an affordable replacement will depend on where you live.

[@user-mp7cy7jj2n]

hi sir may I ask if what is the code no. of the 2 transistor. that attached in heat sink. I need to know because I have a amp like yours. but my amp have a problem. the 2 transistor is missing I need your help Thanks alot

[@alerista]

What part should I get? I have the same issue

[@mowogfpv7582]

This one: uk.rs-online.com/web/p/rotary-switches/1239618 RS Stock No.:123-9618Mfr. Part No.:SRBV181004 Good luck!

[@AriaMusicVibe]

I have the Boss street cube 2. I have the same problem i think

[@birb6377]

It wont come apart please help.

[@mowogfpv7582]

Do you mean getting the handle off or desoldering the switch?

[@ReedHarrison]

13:11 I agree . this will be my last Roland product. They use cheap crap inside and they fail too much. very dissapointed with Roland. I love it when it works but every Roland product I've owned has some kind of issue at some point, mainly because of the subpar parts!

[@tunnel7]

sort your sound out cannot hear you

[@4Marktk]

Time plus materials you could have bought a used replacement amp much cheaper

[@mowogfpv7582]

I wouldn't recommend anyone do this as a business. But it's satisfying from an environmental and from a personal development perspective to be able to keep a repairable appliance out of landfill. Total parts cost

[@tunnel7]

It is a big fault Roland amps are crap build quality I have not come across one yet without some sort of problem with the dial/switches great little amps when they work but not built for the long term steer clear I say and the customer service at Roland is garbage cannot get them repaired very easy.

[@godsownlunatics9650]

I picked up one of these amps at the recycle depot, it has no wires to the transformer so I have no clue how to or where to solder new wiring. I figured I'd fix it and sell it to someone who might play guitar. any idea where the wiring goes to the transformer...any help is always appreciated

[@godsownlunatics9650]

found the pins and fixed the amp...now all i gotta do is learn to screech a guitar. proud of myself

[@godsownlunatics9650]

you ever see perpetual motion? I made this invention in ten hours, I reside in BC Canada of all things and places oddly enough donald j trump emailed me the day after he was elected stating BRIAN-JESUS in the headline. I hope I am not Jesus not because Jesus is a prick but because if I wake up completely and wake to an empty cockpit floating into the sun, what happens to mankind? was it real? am I just imagining all of this. I am so alone I cannot deal with this anymore
