I'm having a amp crisis!

manual of your amp

to replace the tube you have to remove the top screws and remove the top cover but be careful when you work on amps

I didn't see a reply about the tweeter. That would be my first guess as stated above. The bass player in my band was always curious why I keep mine off. I had him fire up his fuzz, turned on the tweeter, and crackle city!

Hey thanks for everyone's tips sorry I didn't do a video yet only because Iv been flat out organising stuff for my wife's brains surgery next week end. I'll get around to doing a vide soon.

Slightly off topic can some one exsplain how they ohm stuff works with amps . I thought you could only run 8omhs amps with 8 ohm cabs? Because I really one one of the orange OB1 500 amps but I thought I couldn't run it through my current 1000watt 8 ohm cab.

Hi,
You have some good suggestions, but look at it as simple replacement toubleshooting. Prior to replacement troubleshooting, take everything out of the signal chain and adjust the tweeter down to off, Also, check your preamp signal and make sure it is not too hot.
At this point simply try another bass. If it still does it, try another amp, if it still does it try another cab. Best to borrow one from a friend or take your amp & bass to a music store. By simply eliminating one thing at a time, it should be easy to figure out. My guess is the signal is being overdriven by pickup height or your amp is peaking and your amp/cab cannot handle it, or it could be a simple tweeter replacement. You will know once you turn off the tweeter and try another bass. But definitely do all this without the effects/eq in the signal chain. Once you determine the problem, add the effects back in one at a time. Do you really need the EQ; in other words have you tried the amps EQ to its fullest? Try cutting the frequencies you don't want instead of boosting the frequencies you do want.

Like you said, it is either the Guitar, Amp, or speakers. Borrow a different bass and try it, if it still crackles then you know it isn't the bass. Then borrow an amp, if it still crackles then you know it has to be the speakers.

Its almost certain its the guitar setup and player attack. That amp and cab are prolific, and successful. I vote for heavy attack, driving the strings too close or in contact with the poles. Its probably happening at lower volume, unnoticed until you crank it. I had that issue, I lowered my pickups and learned to control my attack.

okay so as much as I understand what you guys are saying about the attacking it to hard an pickups to high. But I am %100 this isn't the the case. Iv tried with multiples of my basses and completely removing all pedals from the chain. And it's still doing it sept now Iv lost 50% at full bore of my volume and then the amp will pop and I'll lose signal completely until I turn it off and on again . I videos it but it wont let me post it for some reason.

Ps sorry for the late reply my wife had brain surgery a week ago and Iv been a little preoccupied
