With Zoom (or any other wacky do it all in one pedal unit) inserted in FX loop of any hi gain amp this is always going to be a potential squeal like a pig problem. :duh

Reason is because most hot rod guitar preamps already have a lot of gain  so the moment you use a zoom with hi gain patches then the oscillation will be hard to suppress.

Used in front of amp (as per normal) then it's usually ok.
or as already mentioned zoom into FX return (bypass the Amps preamp) ok.
But not wise to use both hot rod preamps. :loco

Guitar News / Quilter OverDrive 202 - palm sized amp with rock concert sound
« Last post by joecool85 on August 07, 2020, 09:03:39 PM »
Quilter has announced their new OverDrive 202, actually it was back in June but I somehow missed this one.  Anyway, it's a 200watt, 2 channel, pedalboard-sized monster.  I'd love to have one, that's for sure!  MSRP at $575 means I won't be seeing it any time soon though.

Sounds like shot power supply capacitors to me and/or rectifying diodes.  Regardless, before trying to turn it back on, open it up and look for any burn marks etc.  If all looks good, then build a quick light bulb limiter, plug it into that and start taking voltage measurements with a digital multimeter (we can help here).

Have you checked your FX loop? a common cause of intermittent signal drop out.
Phil.

Phil is on it.  Try running a patch cable between the FX send and return jacks.  If this fixes it, your jacks just need to be cleaned (or replaced if it really bad shape).

I've checked with a couple of local electronics repair places and they want more to look at the Amp than the Amp is worth. I've recently purchased a Blackstar HT Stage 60 for myself and was hoping to get the Crate fixed, as inexpensive as possible for my teenage son to use with his guitar. Thanks for the comments so far. I'm taking your suggestions into consideration.

Hi,

> Try the guitar into the Zoom & then go into the FX Return jack.

This is something new to me, Ill try it, thanx!

I have put Zoom infront of the amp Guitar > zoom > amp - and is normal, how is should be.

Later I have connected Zoom back to Fx loop, selected noisy presets (now with the headphones on) and went into the setup menu of each added effect / amp.
With muting an effect the noise was gone.
So I suppose that what you say -the gain could be the problem, maybe with the heavy distortion, flanger  ..
But I didnt have too much time now to go deeper in setup, so thats Todo

Cheers

BLows fuses?  Start at the start.  DISCONNECT any speaker, if it still blows fuses, then check for shorted output transistors.

i bought a peavey musician series 400 amp about a year ago. i played it for about half an hour then i got a lot of distortion. i turned it off. when i put it back on it would not come on. it just gave a putting sound from the amp and blew the fuse, anyone have any ideas where to look.

thanks.

Try the guitar into the Zoom & then go into the FX Return jack.
This will tell if it is a Send circuit issue or a Return circuit issue.
Be aware that you may have to adjust the gain on some of the Zoom presets.
