I never would’ve thought of this on my own. But it makes so much sense when you explain it. It was sure a lot easier than opening up the amp and tinkering around. Thanks for the simple fix.

Thanks a lot James. I ran into this when re-tubing a Marshall JTM 30, and this bypass loop keeps input signals very consistent and I haven't heard anything since from the musician. So thanks for the reminder since I just got in a 1980's Roland Bolt 60 with the same reported issue. You saved me a lot of angst!

Thank you James, my amp had all the symptoms you mentioned, I tried replacing tubes but the patch cable fixed my mess boogie dual rectifier amp, now it sounds great, many thanks to you for sharing this fix 😎👍

This man is a freaking genius. Wish I had know this years ago lol

You just fixed my Magnatone super 59 sprayed a little cleaner In the loop connections now i’m back to the great sound I know and love thanks

My man, you just gained a subscriber. Wow...I've been fighting this one for a couple of days and was getting ready to take it in. Found your video and it's been playing absolutely clean for about 45 minutes now. Thank you!!!

Thank you sir, I've been putting this off for years. Your video was a real help.

My problem is that I lose volume when I use the effect loop... For years I plugged a Boss GE into the effects loop to boost my solos, but suddenly when I press the pedal I lose volume.. a lot of. If I switch the amp off/ on the power comes back. I use a DSL 2000 50 watts. Can anybody help me?

I ran the pre-amp external output of my Marshall 8040 to its main amp external input and voila! Problem solved! No more clipping and fade-out! Thanks for providing us with your knowledge!

Good day. It is 7/15/2023. I purchased a Vox VT100 that fuzzed out. I purchased it cheap probably because of that. I was on my way to do something drastic and then I saw this video. I had a short 90 degree pedal cable and connected the send/receive jacks in the back. You are absolutely correct. I will never use the loop jacks so the cable will remain. I now have full volume all the time. Maybe I will try the cleaner though. Thank you so much. Correct Information is powerful.

Wow, thanks so much! I have a 30 year old jcm600 marshall replaced tubes and was so puzzled thinking power drop off meant a power tube problem. Not my old Marshall friend and I can get on with things until I get a permanent fix. Much appreciated!

Man this made my whole night! My Blackstar HT Stage 60 has been down for over a year now and that just brought her back to life. Didn’t work on my Marshall DSL40 Vintage but that might be a preamp tube. Thank you for this video!

I just fixed my Bugera 1990, thank you so much James!! That explains why the output transformer was working so hard, because of the resistance in the FX loop. Transformer is staying cool and the amp is running great. Very helpful!

Thanks so much. This solved an issue I was having with a Marshall as50d acoustic amp. Jumped the send and return and it worked perfectly!

Thanks for sharing your knowledge! I have exactly this problem with two Laney valve amps!!

Amazing!!! I got a Vox AD60VT amp from 2001 year, that was completely dead with no sound! I plugged in a guitar cable into the Loop effects Send and Return.....and it now everything Works just like New!! Even the foot controller pedal. Unbelievable! Amazing! THANK YOU! So much Sir!

Likewise man you saved my laney tube amp thank you you are a guru of the amps awesome I found out it was effect loop circuit fortunately amp has a bypass thanks again absolutely awesome

I could’ve spend hours browsing forums for this info or I could’ve watched this. Seriously, thanks for your help on this one, friend.

Worked like a charm. Thank you very much!!!

Replaced my tubes, changed my cables, etc. Nothing was helping... until JAMES SAVED THE DAY! Thank you sir!

Amazing. jumped the loop and it is working great. Thanks so much

Great observation. This is a common issue and the contacts in the jacks are the culprits.

I’ve done a lot of diy fixes to save my amp except spraying contact cleaner in the input jacks. My amp doesn’t have a send/return, but tried the fix on the main input, the footswitch input, line out , and headphones outc and it worked! Crackling and sound dropping are gone. Thank you!

Fixed two amps with this advice...thanks for posting!

Thank you very much James,just fixed my amp too!Cheers

GC30 Laney lives again. Patch cable worked instantly. Thanks for sharing.

Took mine apart and noted some the jack pins were loose so cleaned them and push them back into place and no more drop out, very happy now😀😃😁

My Marshall 2553 is back! Thank you so much. I was about to replace tubes. Thank you, James!

After years of pulling my hair out with this old Peavey bandit 112, you have discovered the problem! Thank you sir.

I changed all my valves and this was the problem! Thanks! Solved it just patching the effects send to return.

I never knew this. Marshall is back cranking! Thanks!

Thank you so much for this video!! I've spent months trying to figure out what could be the issue and finally it worked like magic! I was just about ready to throw my amp out the window as the local tech could not remedy it. Thank you!!

Thanks so much. I was ready to scrap it. Your fix made my mg250fx play like new

this fixed my Peavey delta blues amp. Thank you for sharing your knowledge

Just bought a used amp that appeared to be in great condition and worked great when I was testing out at the previous owner's house. When I got back to my place and started playing with it, the signal "buzzed out" as you described a few times. Flipping it on and off standby fixed the problem in the short term, but I was understandably concerned about my new purchase. Then I tried this solution while it was in "buzz out" mode, and the signal returned right away. Thank you so much! I should get around to cleaning/replacing the effects loop jacks, but this fix is wonderful.

HOLY CRAP THIS FIXED IT. My Marshall did this almost since I bought it back in 2004, I would clean everything out and it would seem to fix it. I even brought it to shops and they didn’t know what was wrong, they would just clean everything and it would work again. The problem came back today after 7 years and this fix was perfect.

Thanks your right man. I made a bypass for now quick fix. I will get a new input jack soon. Thank You So Much.

Wow! Thanks for the tip. I had the same issue & I pressed the loop bypass button & the problem went away! Splawn quickrod 100

I’ve noticed the last 2 times I’ve played my Peavey Bravo 112, the volume cut out, and quickly went down to barely audible. I’m going to try using a patch cable before messing with replacing tubes. Thanks for the advice!!!

Thanks James for this great tip! Just tried this fix and so far so good. (Have Vox Valvetronix 60W)

Like all brilliant ideas, it is very simple! Thanks, dude.

Thank you so much James.! I thought my Randall Rg100 classic head was a lost cause. It was just sitting collecting dust for the past 10 yrs.

Thanks, I have a older tech 21 landmark 60 bass amp that was cutting out, worked a plug in and out of the effect loop Jacks (that I have never used) and amp came back to life.

Worked for my Ampeg SS-70, thanks!

Oh wow damn. I've been having these kind of problems. I have a sonic maximizer going through my effects loop. Thank you sure! I haven't tried it yet, but this gives me hope that when I sober up I can fix this.

Great tip matey, thanks for that one.

By plugging in a Patch cable in send - Return loop ( Never used the effects loop ! ) , It definitely solved the "Drop out -volume " & Noise problem with my 10 year old SOLID STATE Amp ( Hughes & Kettner - Edition blue ) ! Seemed those send-Return inputs were heavily corroded ! THNX !

Genius, going to try this on my old Crate 60w tube that's been cutting out. Thank you

Thank you sir, you have saved me. I just bought an amp yesterday after testing it in the ex owners house, where it worked just fine, but had this issue when i got home.

I ended up selling that amp and bought a new one. But instead i did tell the new buyer about this and gave him a patch cable to close the loop in case he wasn't gonna use it.

thank you for this i've been wanting a reason to jump the FX loop on my JCM800 anyway. i had this problem while practicing today. wish me luck im gonna try it!

This worked on my Marshall 5210. I ran out of contact cleaner but have some on the way. I cleaned the pots today and will try cleaning out all the inputs. The amp has a bit of static going on but a cable in the effects loop prevents the cutting out and volume drop like magic.

This actually works. Thankyou so much I've spent two days trying to fix this issue, thought it was my guitar at first was devastated .Again thankyou so much . Pulse 200 pa system 4 channel.

Thank you for the tip I am having this problem I hope it works

Man, thank you!!

Thank you so much! i just plugged my cable in and out of the efects input and out, they were just a bit dirty

Thats exactly what I did whahahahah. Just had new tubes installed and the amp cuts out. I read somewhere that effcts loops jacks go bad over time, and cuts the signal. If you plug into these jacks they may not return to the bypass position and remain cut off becuase contacts are dirty or the spring doesn't want to come back to the proper position. So the signal gets cut. And I figured what if.....I patch a cable into this. Lo and behold the problem vannished. Looked online for a video regarding this and found this. Thanks for the confirmatory info James. This fix will save you a costly trip to your tech.

My exact problem I had with my ibanez tone blaster 100h. Thank you sir

Thank you sir. I will definately try this.

Thanks so much for this information, it worked for me.

I have been bashing my marshal amp to get it to work every time I use it... this tracks with this problem. Can't wait to get home and try and bypass the effects loop!!!

Right on! Thanks, that fixed it.

Wow! Nothing talk about that!! Thankyou very much!

bruh wtf. i thought my amp was gone and they i did this. it works now. thank you so much

Great information sir.thanks.

Thanks man!!!! You saved me much frustration and $. Blessings!

Thank you very much, just fixed my line6 by spraying the jacks.

I just did the exact thing you said. I sprayed it with contact spray and plugged in them cable a few times and bam! Thank you very much, I was going to throw out this cheap practice amp!

Excitedly, I tried this to no avail. That said, I took the circuit tray out of my amplifier and turned it over. I found that a resister had come loose in the solder connecting it to the board. I reflowed this solder and added a touch. Now, all is good. Thankfully, mine was a easy fix. (Amp: Marshall MG50DFX combo)

Brand new amplifier had this problem and this fixed it. Initially I thought it was power amp tubes but I plugged my guitar into the FX return and the issue didnt occur. Was happening on both channels so I shorted the send and return and havent had the problem since.

I just want to thank you so much for this advice. I had an old Marshall jcm 2000 dsl 100 that I stopped using years ago because of the volume fading out intermittently. I replaced all preamp tube sockets and resoldered everything in the amp, thinking it was a cold solder joint but nothing worked. Finally I had to purchase a newer version of the dsl that in my mind is sub par to the original. I just found your video today and tried your solution. It worked wonderfully and I’ve been playing for several hours now without any issues!! Again, thank you so much for this advice!!!
