It's a common problem with simple true bypass switching, it's caused by DC offset in the input/output capacitors - I'll spare you all the jargon but essentially when you hit the switch the voltage in these capacitors (which is part of the signal path) changes dramatically very suddenly, which you hear as a pop (kind of like how if you plug a lead into your bass while the amp's on).

It's a pretty easy problem to avoid or at least mitigate and to be honest I'm really surprised these EHX pedals are doing it. I've never heard of a speaker/amp being killed by it though, it's a very quick spike. Short of modding them you could put them in a bypass looper (with a better bypass) so the pedals themselves are always on.

 

Bob @bobbass4k I missed your response earlier. The pop is trouser-flappingly loud. What is a bypass looper? 

I've no idea what I'm doing with the @ thing btw...

Bob.

I'll try the switch thing again @jrixn1. Tried the multiple on and off @burno70 and still pops. I think it's worse on the soul food. I'll try them both when l get home. Shame as they are great pedals but it's putting me off using them.

I think it's something to do with true bypass, is it not? My Neo Clone is the same.

Yeah, I thought the same, so opened up the Soul Food and switched it out of bypass (well, I think that's what it does) and still thumped. When things are cranked up - and let's face it, that's most of the time - it feels speaker damaging. 

I've got a Soul Food Bass and a Big Muff Deluxe, both of which give a really loud POP when switched on. I've tried using a battery, different power supplies, different leads, switching on and off a few times and still that pop is there. Do they all do it? From a search on interweb, it seems this happens on the guitar pedals, but couldn't find anything on bass ones.

My whole life seems blighted by electrical pops. If it's not the old Marshall solid state (ditched now, but thanks for the advice, forum people) it's my pedals! Never had a problem with Boss, may go back to them, although the Soul Food is so much nicer.

Cheers,

Hi all,

 Anyone know if these pick ups are the wrong way round? I read that the raised pole pieces were to combat a weak A string but these are  under the D and G. It's a MIJ 62 reissue from 1991.

Cheers.

Thanks, I'll get onto that. Likely to be resumed  when I get one and realise I haven't a clue how to wire it in. 😀

😀 yes, I've been doing that but I'm likely to forget. And I always need something to tinker with (stop sniggering at the back.)

Hi all,

I picked up a Marshall IBS 100w head at the weekend for literally a few quid. It works ok and is quite nice in its own way, but makes  really loud pop sound through the cab when switched off. It sounds like something discharging. It is proper loud, not a normal shutting down sound. Any ideas of a fix? I looked inside and no burn marks - some huge capacitors in there!  

cheers.

Yes - this is exactly it. I shifted a lot of very good heavy old gear and went Markbass and Barefaced. And somehow I find a behemoth of a Trace Elliot rig looming over two all valve heads one of which I seriously contemplated buying an engine hoist to move.

You see, this is not about the rational. Oh no.

I'm the same. Downsised to a lightweight cab but now find myself bookmarking a GK 8x10 on this very forum and planning journey times to pick it up. Oh, and I'd have to borrow a bigger car to get it and borrow both sets of neigbours to get it up the 17 steps to the front door. But I still want it! As you say, this is not about the rational. Now, back to Google maps.

John Paul Jones. Just because, well, he's John Paul Jones.

Bought a pedal from Brian. Easy transaction, fast delivery. Top bloke!
