Broughton Audio Super Thread

Late morning post-gig breakfast. I'm hoping it will induce a nap.

So I’m getting an intermittent glitchy, scratchy sound coming from my recently acquired new-to-me SV-PRE pedal.

Turning it off silences the glitch. Turning it on eventually leads to the glitchy, unwelcome sound at some point. I don't notice it when I'm playing, but only in times of non-playing.

My chain is: Passive Basses > A/B box > tuner > SV-PRE > PC-2A Compressor > SexDrive > D-800+ or ShuttleMAX 9.2

Before I go ‘xperimenting to find a possible solution, any suggestions come to mind?

Some possibles, but I'm just spitballin' here... first disconnect and reconnect everything. Second, what is your power supply. Third, is the SVPre near the power supply? Fourth, do you get this sound if you only have the SVpre going into either the D-800 or Shuttlemax?

Does it do the itchy scratchy when it’s the only item in the signal path?

1. Check
2. Cioks DC-7
3. Pedals are on a Nano board; DC-7 mounted underneath
4. Going to try that later today at rehearsal (on my to-do list).
 
Where is the SVPre in relation to the Cioks? You might also want to swap in new patch or power cables. A hinky cable can make the weirdest things happen...

SV-PRE is sitting smack dab over the middle of the Cioks. That shouldn't be an issue should it???

Yep -- bring my bag of patch cables to rehearsal.

If the compressor is set for maximum squash, it might have the effect of raising the noise floor of the SV-PRE.

Hadn't thought of that. But in my case, I've got minimum squish dialed in.

My Sv-pre sits right on top of my top of my one spot and I've never had any issues with noise, but I've heard of it being a thing.

Location can be an issue, yours? I dunno, all of these suggestions should get you there. Isolate and build up from there. If it indeed is the pedal Josh can help you sort it out, not saying it's damaged, but unfortunately this is one of the few pedals that can't take more than 9volts if accidentally sourced higher.

I will say, the SVpre can be a high gain pedal, which will expose other noise you may have not heard to begin with.

This is always worth a consideration. There’s been plenty of folks that have “whoopsed” with the voltage and reported that the pedal still worked fine after but I wonder if that can hurt the lifespan of a component into failing later on.

chargepump no dig it, also there's literally a note on the website about noise and clean power "Power Supply Notes"
 

Don't think it's the close proximity of the power source. I separated the SV-PRE from the DC-7 -- took it clean off the board. There's still the intermittent pac-man like sound being emitted from the Bass > SV-PRE > amp chain. Before that, I also tried different patch cables without success.

Also possible

Yeah -- high gain often translates into additional noise (I dime the master with the gain at 10:00).

When I move pedals around I double-check the dip-switches. The SV-PRE is at 9V. It's good to know that it might take a walloping at 12V+ and survive (not good in that it could shorten its longterm usefulness)

The plan is to consult with Josh sometime this week and start the troubleshooting process.

I do like this pedal. :thumbsup:

Thanks everyone!
