Ah shouldn't be that issue, but Sushi should be around with some ideas later It's definitely be odd to damage a tube like that but I guess not impossible.
Just for fun, have you tested the pedal by itself to make sure it happens alone? Only thing on the power, only pedal in your chain.

Thanks for all the thoughts, greatly appreciated. I just picked up a cioks power supply for a new board I’m building and just tried it as is the only pedal in the chain hanging off the new cioks power supply just to be safe…unfortunately still squealing

It’s a long shot, but try moving your power supply away from the pedal. I’ve notice some odd noises if mine are too close.

unfortunately no change in behavior. Maybe @Sushi Box FX can chime in on any other possible issues.

If you want to get ahead of him, I know he'll ask for this since it was used to you/no way of knowing the original order date/version:
Unplug power from your SlamX and let it sit for 15minutes (power to dissipate). Then remove the rear cover, and post a picture of it. That show Sushi which version it is/in case it needs the grounding mod.

Partially Nobelium builds, partially something else that you'll be hearing about in a few weeks.

@Pedalnetics is correct, I'll definitely want to see a picture of that circuit board. It will show me whether or not it has the polarity fix implemented and will also show me which version of the board it is, some of the older ones did sometimes have issues when the gain was turned up high while the treble was up high.

So I just got a 5751 tube for my first attempt at tube rolling. I installed it in my slampegg x and immediately found it squealing when I turned the gain past 2 o’clock. I snapped the original back in while formulating an email back to the supplier in my head, however after putting the original tube back in I noticed that is now squealing with the gain knob in the same place. I guess I could have messed up the old tube when I removed it. Anyone ever have this experience? I did end up reaching out to the vendor who is sending a new tube just in case it is a tube issue but am concerned I did something to the pedal.

Sounds like the potential grounding issue from a while back; how old is your SlamX?
@Sushi Box FX should have some guidance ^^

I am experiencing the same issues, and have tried separate, different, isolated power supplies, and new tubes to no avail. There is also a faint whistle that won’t go away until I unplug the unit - when in bypass.
I think mine might be from just before the change. Do I need to do a mod? Thank you @Sushi Box FX

It looks like yours already has the polarity fix. Is this just when other things are in the chain, or does it happen when the pedal is by itself?

I took some time and moved pedals around. It seems like moving it closer to the front of the chain resolved the issue! I guess it didn’t like being behind one or two of my other pedals.
I promise I am smarter than it would appear.

Thank you @Sushi Box FX !

It’s weird tho, because when I initially found this issue it was because I had taken it off my board for a while. One day (my previous post in this thread) I plugged it in completely by itself, and that’s when I first noticed the squealing - as I turned the gain up past 2; which is higher that I ever used it before. Gremlins, I suppose. Anyhoo, all is well now.

I just got a Slampegg and I love it. Clean but with some grind.

Hey there fish fans, I think one of these preamps might fit my needs really well and I wanted a little input. I have one setup that I use for guitar and bass, and I run DI or through headphones 99% of the time. With my pedal setup I don't need multiple channels from a preamp, I'd be using this as always-on and relatively clean. I've been using my Ampeg Micro VR as my preamp into a cab sim, and while I'm mostly happy with the tone for bass, the cleans are a little sterile for guitar. I'd like to simplify down to just having a preamp on my board that would be at the end of the chain, run into my cab sim, would work well for both instruments, and add some much needed tubey warmth. For bass I like a mid-forward sound with occasional grit (think SVTs, pop punk), while with guitar I lean a little more Fender-y. So I was thinking the UA because of its showman-derived nature and the ability to bypass the tonestack seem like a big advantage. My bass is active so I could simply bypass the tonestack and cut some volume when on bass and leave the EQ set where I'd want it for guitar? But, the Elementary seems like the best guitar-sculpted option (and that one guitar demo on youtube sounds so good). Or should I just go with the Slampegg since I like the Ampeg sound anyway and it has more EQ options?

Underground Accelerator is my choice because of the eq off switch. It sounds great on guitar too.

Welcome to TB generally, and the Sushi restaurant specifically!

I'd think, based on how you describe it, that either the Elementary or UA would be a good fit for your needs. I'm not convinced the Slampegg will be the ideal voicing for guitar, even if you do like the Ampeg sound on bass. It wouldn't sound *bad* but I also suspect the other two would be better for clean guitar. I'd probably favour the UA due to its increased utility for you specifically, as compared to the Elementary; having the option to quickly change volume/EQ via the TS Bypass switch should make swapping between passive guitar and active bass a fairly simple and quick job.

I would suggest either the UA or if you can still snag one a [This invalid link has been removed] that sounds brilliant on guitar.

Yeah the extra cost there is tougher to jump at for a first sushi pedal without any demos around, but it definitely is tempting. Shows 10 in stock on the website still.

I’m sure you could flip it if it doesn’t work out. There were a limited number of them built.
