hey the volume knob on my SP 404 is broken. When i move it there is no change in the volume and it stays very low. However, if i push the knob to the left, it clicks back into place and works fine, but only if i keep pushing it the whole time. Does anyone know how i can fix this?

if you can solder or know a cheap electronics guy, it sounds like the knob has come off the board at one of it's points.

otherwise, buying a used sp-404 might be cheaper than having Roland fix it. do you have a warranty, if you bought it used then i guess not.

yeah, i got it used unfortunately. that's what i expected happened but i wasn't sure. Is there a way to take of the top (silver faceplate) of the 404? I took off the back but it didn't seem like i could very easily get to the volume knob from there

I haven't done it, but you need to pull of the knobs for sure. I think u just unscrew it after that and pop it off. If you're worried then just find a local electronics repair shop and have them fix the volume knob, it should be pretty cheap and easy for them to do.

Hi, did you manage to get this fixed? I have the same problem!

unbelievable. I have same prob on my 303, 'cept it's stuck on '10'.

cartesia told me what's up, but i haven't fixed it yet. when i have access to necessary tools, i will give it a shot.

i guess 'volume' and 'ctrl 3' get bashed during transport because they are the most exposed.

Hey guys, I this is a mad old post and everything, but I was wondering if you ever got your knobs sorted out.

Naw, not yet.

But honestly I'm gonna give it a go in the next week if I can.

my fx knob 1 is kinda broken , but it lets me not twiddle as much, other than that, my 404 og v1. works perfect still, even though shes mad thrashed.

Let us know how it goes. If you are worried about doing it yourself or just wanna get rid of it holler at me. BTW remember to use flux, it helps alot.
