Hey guys!

I've recently got into building a stereo amp setup/pedalboard and unfortunately have ran into some issues I can't seen to figure out on my own connecting everything. I was wondering if anyone from the Toronto area would be available to come by and possibly help me get the issues straightened out? I'd gladly pay for your time

If you or someone you know might be able to help let me know

Cheers!

Yes post pics and write out the pedal order / chain. You can just say Boss OD1 ---> Chorus ---> etc.

Thanks for the replies everybody, I've tried to map out my signal chain in this diagram and hope its not too confusing

I'm running Loop 1 into a Marshall a Silver Jubilee and Loop 2 into a Marshall DSL 100 set to clean. I'm running both heads at 8ohms into a stereo Marshall 1960B 4x12 cab and switching between heads with a JHS A/B pedal at the end of my chain. The board is being powered by a Walrus Audio Phoenix power supply and the MXR EQ and H90 and being powered by their own power supplies

The issues I'm running into are the following

-Massive volume/tone loss on both amps when loops are being used
-The Timeline works okay but when the Boss DC-2 or Eventide H90 is activated there's a HUGE volume spike
-The Fortin Zuul and MXR EQ are effecting the other loop even though their not in the signal path of the secondary loop
-The EQD plumes is after the A/B pedal so I can leave it on as a boost all the time and not have it effect the clean amp when I switch over. Unfortunately when I do switch it on it's still effects the clean channel and adding noise even though its isolated in its own loop by the A/B pedal

I really appreciate all of your help and comments thus far, I've bitten off more than I can chew with this set up clearly and would love some help from more experienced rig builders. If I can't get these issues straightened out on here I'd gladly cover the gas/time of someone if they'll come hangout for a bit and help me get it working

Thanks guys!

OK, so not a simple signal flow. To be clear, when you say you got both heads driving the stereo 4x12, you are using it as 2 2x12s in one box right? Like each head is connected to 2 dedicated speakers vs all 4 in mono mode e.g Jubilee to the "Left" stereo input and the DSL 100 to the "Right" input? Also is the chain like this:

...............................................................................------Loop1 -------Amp 1
Common section chain -----JHS A/B--|
.............................................................................. ------Loop 2 ------ Amp 2

have you tried with a different aby pedal like the radial one? I’m wondering if maybe there is a polarity issue.
I also am not very smart with this stuff and could be 100% off the mark, so keep that in mind haha

also The real problem is the dimension chorus and you should ship it over here for me to keep away from your pedal board! 😆
