Members Battery Posted August 5, 2011 Members Share Posted August 5, 2011 I just played my blockletter 5150(was bought used) for the first time in months, but when I plug effects into the loop the effects don't respond. I still get normal volume, but the loop ignored my EQ , flanger, and chorus pedals. I know the pedals are not the problem, they work fine when plugged into the front of the amp. I plugged the input of the pedals into send, and output into return; don't understand why it wouldn't be working. If there is a problem with the loop, is it worth getting fixed on a 5150 or is it better to just use the front, even for modulation pedals?

Members guitarbilly74 Posted August 5, 2011 Members Share Posted August 5, 2011 Do you have the footswitch plugged in? Is the loop turned off? Sorry to ask such a basic question, but hey.... Link to comment Share on other sites More sharing options...
Members Battery Posted August 5, 2011 Author Members Share Posted August 5, 2011 Well I'm away from the amp now, but yeah there is a footswitch plugged in. Like I said I haven't played it in awhile. Sorry to seem like a n00b, but you think the footswitch could be the problem? Link to comment Share on other sites More sharing options...

I BET the loop is turned off in the footswitch Link to comment Share on other sites More sharing options...
Members guitarbilly74 Posted August 5, 2011 Members Share Posted August 5, 2011 Do you have the stock footswitch or a different one? 1 or 2 buttons? Link to comment Share on other sites More sharing options...
Members Battery Posted August 5, 2011 Author Members Share Posted August 5, 2011 It's a custom footswitch if that matters, but yeah maybe that is the problem. Bear in mind this was my first amp head. Link to comment Share on other sites More sharing options...

I am 99.9 % sure that's the problem. Very simple to find out for sure: try again without the footswitch plugged in. If that fixes that problem, call Peavey and order the right one (or get an used one from eBay etc... ) Link to comment Share on other sites More sharing options...
Members wrongnote85 Posted August 5, 2011 Members Share Posted August 5, 2011 i have the same amp, but alas, i have never fuct with the effects loop. if you have a two button footswitch you should be sure to check that the loop is engaged there. hint, it will be the button that does not change the channel from rhythm to lead.

Members BenoA Posted August 5, 2011 Members Share Posted August 5, 2011 I'm with guitarbilly74 above! Good advice. If you have a stereo plug, just put it inside the remote input in the back of the amp. By default, it should activate the FX loop. Tip of the plug is the FX loop, ring is the channel switching. Try it out and keep us posted. Link to comment Share on other sites More sharing options...

Members darkestdays Posted August 5, 2011 Members Share Posted August 5, 2011 I am also having problems with my 5150 FX loop. It acts like it's a parallel loop, but I e-mailed Peavey, and they confirmed that it is indeed a series fx loop. I get no volume when using the Axe FX four cable method. I've posted about this before here (fractal forum. hope a cross thread link is ok). If anyone wants to read through the thread, and try to help me out, that would be awesome. I've also tried the fx loop with my MXR 10 band eq, and it just acts like it's in series. It's like it's just blending the fx loop signal with the main signal. I have tried it with, and without the foot switch. I dunno, I got frustrated, and pretty much gave up on it thinking I would eventually take it to a tech.

Members BenoA Posted August 5, 2011 Members Share Posted August 5, 2011 @darkestdays You must have some issue with the FX loop as my Boss GT8 works great with my 6505 with the 4CM. Link to comment Share on other sites More sharing options...

The fx loop tube is shared, so a small signal will bleed inside the tube. It is common, but become negligible once the volume is louder. Try different tubes to find one with less internal bleeding...

Members darkestdays Posted August 5, 2011 Members Share Posted August 5, 2011 Thanks guys, I figured I'd have to take it in. I bought the thing second hand, so who knows. Shask, it's not really internal bleeding that is the main problem. It's the fact that I get no volume with the four cable method. It's like the Axe Fx isn't getting an effects return signal, but I've tested the fx loop with pedals on the axe and it works. If you still think it's a tube, I will give it a try. Do you remember if it's v4 or v5? Link to comment Share on other sites More sharing options...

Do you remember if it's v4 or v5? If you put a cable in the send, and one in the return and don't connect them to anything you should technically get no sound since its serial. But, its common to get a low volume sound that doesn't change much with post volume changes. This is common, and is the problem that I mentioned. Anything beyond that might be some weird problem yours has.... Link to comment Share on other sites More sharing options...

I didn't think to try that. Thanks! Edit: Didn't mean to derail the thread. Did you get your FX loop working Battery? Link to comment Share on other sites More sharing options...
Members Shask Posted August 6, 2011 Members Share Posted August 6, 2011 Oh, and when I have messed with 4CM with my 5150 and POD HD500, I have to put the post on the 5150 on like 4-5 to come out right.... I then balance the volume with the HD to get even levels... Link to comment Share on other sites More sharing options...
Members Battery Posted August 6, 2011 Author Members Share Posted August 6, 2011 Yeah I just got back it, was the footswitch. While we're on the topic, let me ask this: If I do the footswitchable crunch channel mod, will the 2 button switch I currently have be of use to this?

Members nandus Posted November 15, 2016 Members Share Posted November 15, 2016 had the same problem, footswitch was the culprit:in the 5150 fx loop is engaged when switch aint plugged inand it actually worked whithout fswitchbut with remote plugged fx was'nt engaged and pressing the swicht dind'n even turn the led onso I opened it and realized that the tip signal that controls the loop passes thru the led before getting to the switchso when the led is dead signal won't passchanged the led, everything ok(the led was covered in glue, had to mess with the solder and breathed that {censored}.. I feel a bit dizzy and headached... but maybe I always do) Link to comment Share on other sites More sharing options...
