    Low Tech Origin FX Loop Solution...

    I already did some searches on this topic, but didn't find a specific solution. I know the FX loop default setting is 'off' and the amp requires the footswitch to turn it on. I saw someone make the following comment in an older thread.... " ...you could probably build a dummy plug to act as...

    SC20H FX Loop Noise Concern

    Hi all, I purchased a brand new SC20H recently, and ultimately, the amp rules. The tone is everything I've ever looked for. Classic 80's Zakk Wylde tone when boosted with an SD-1. I love it. HOWEVER, there seems to be some FX loop issues, and five minutes of research was enough to verify that...

    JCM2000TSL - Send/Return Problem

    Hi all, I recently bought a Marshall JCM 2000 TSL, it sounds awesome, but when I plug any pedal through the FX loop the volume suddenly drops. If I hit the top of the head with my hand, the problem solves temporarily , but after 1 or 2 minutes of playing the volume drops another time. I am an...

    Marshall mashup: MG30FX in an Origin20c's FX loop?

    Similarly to using another amp as a slave of an origin amp (say, to use its preamp and power amp in the slave), can I use the slave amp as a "FX board"? Specifically, if I have a MG30CFX combo and an Origin20c, can I place Origin's "send" to MG's input (or line/mp3 in? probably not subject to...

    Quick Question on FX loops

    Hi Guys, So I’m trying to use my fx loop more - I got the return and the send mixed up on the pedals- the amp made a bit of a hiss and that was about it. Normally I wouldn’t mind but I’m trying to be super careful with the valves- would that do any damage? Also I need to get good reverb...

    FX Loops- a few questions

    Hey guys, So it only hit me recently.... m is very very poor- particularly when I've worked in a studio for years. I find myself generally working as a mix engineer/online service where we mix more than actually track and I think that may be my reasoning for my knowledge sucking so bad! Any...

    Is it possible to use a digital reverb (for example a plug in from logic) as an Fx loop into an amp?

    Any suggestions would be great!

    Code 100H FX Loop

    I just started playing with my FX loop on my Code 100H and found a couple of disappointing things. First, all outputs except for the cabinet come before the FX loop so I cant record via USB using anything in the FX loop (nor can I hear it through the headphones). My looper is particularly a...

    JVM 410H FX LOOP HEADACHE

    So... For some reason or another I cannot get the serial loop to work using pedals, and I cannot get the parallel loop to work at all. So far I have eliminated any cable and pedal issues (Through the front of the amp everything is fine) I have only tried the OD2 channel but i don't see why...

    FX loop problems (?) on a valvestate AVT 2000 50H

    My band plays out a lot and I’ve borrowed my bass player’s Marshall Valvestate AVT 2000 (50H) head and 4x12 cab. I use an old L6 POD only for vol pedal, boost, flange, delay, and rarely extra reverb, so I send the pod into the FX loop (I only have wah in-line to the front between me and my...

    Hi all, I have a JCM 900 4100 and the FX return is not working. I can get a signal out of the send just fine, but if i try to put any signal into the FX return, I get nothing. If I bridge the send and return with a patch cable, when I crank the master volume I get a very low volume...

    Marshall Origin50H FX Loop sucking highs out?

    I have all my modulation in in the FX Loop "Volume Pedal" first & I like it. I accidentally turned off the fx loop today & it's like my Origin came alive with that great vintage Marshall sound & brightened up & got more crunch. It also seems to get a bit quieter with the fx loop on. Anyone else...

    Hi All, I have two VS100's. I also have the schematics (it's 4 parts) but no voltage charts. My problem with a strange buzzing when I use the FX loop. There's something going wrong with the board, but I'm not seeing anything obvious by reading the schematics. The buzzing is only present when...

    Fx Loop Broken. Gig In 2 Weeks. Possible To Replace Loop Circuit?

    Hi there, I have a problem with my JCM2000 DSL's fx loop. Basically the problem is that the amp works for about 10 seconds then there is volume drop. This is when there are cables plugged into the Fx loop. When I take the cables out the amp works fine. I just got this amp serviced/repaired...
