    So I have a love hate relationship with my TSL60. I love the sound I get out of it, I just wish I could use my delay and modulation in the effects loop. Right now I have them out front and then that inhibits me from using them with the TSL's built-in crunch and lead channels. FWIW, the lead channel can dial in a great Sweet Child o Mine tone that I love.

    The problem is this: the effects loop is parallel. Whenever I use the delay and modulation in the loop, even with the effects mix knob on 10 and a booster in the loop, it still does not sound quite right and I can't get the effects as pronounced as I like them. I would love to be able to convert it to serial. Is this possible? Does anyone out there do mods for this or know how? Or am I doomed to sell the TSL and get a different head? Kind of upsetting considering I finally found a head that I like.

    Have the same problem with my DSL401 combo, the parellel FX loop provides a direct signal that is usually 180 degrees out of phase with most effects, so if your effect is providing a direct (dry) signal the direct will cancel. some effects that have only one output will not work in the effects loop, you need an effect that has a seperate wet, dry output or if the effect has a mixer, set the mix to 10 so the effect is providing only the wet signal.

    google parallel effects loop, I had seen some conversion on the web, but not finding them now.


    here are free marhall schematics, you might find an easy fix for the parallel loop

    You might not like my suggestion, but I've given up on loops. The only way I know for you to preserve your tone is to re-amp your time based f/x with a 2nd amp using the line out on the back of your main amp.
    Maybe you can find a 2nd TSL/DSL used or even something else that will just amp your f/x?

    I'm currently not gigging, so I use another amp for this, but I was actually thinking about grabbing a small combo for my re-amp/wet sound and placing it right next to my other one so it sounds like the dry & wet signals are all coming from the same source.

    A fix for the out of phase direct signal can be accomplished with a couple of different boxes by Radial. They have the Bigshot Mix pedal with a phase switch or their ABY switch will work by using the transformer B side of the unit and changing the polarity. It might help to know what efx units you are using. Sometimes running two in series can be a problem.

    My amp has a parallel efx loop but the delays I use all have the ability to get a 100% wet signal. My EVH Flanger doesn't and it is out of phase in the loop.

    Right now I'm running:

    Strat -> EB jr -> OCD -> DS-1 -> Micro Amp -> MXR Stereo Chorus -> DD-20 -> RC-20XL -> BBE Sonic Stomp -> TSL60

    Would also be great to get the RC-20 to play nicely in the loop so I can record the Marshall's sound instead of record a clean phrase, loop it, and then swap the Marshall channels (though I haven't tried the RC-20 there since I got it).

    The MXR Chorus should soon be replaced by a TC Nova Modulator.

    Kind of the worst configuration, Marshalls not the greatest clean amp in the world, but its a great amp, as flameout said running two amps live is good, I would run a distorted Marshall direct and Fender clean amp wet off of a Memory Man pedal, really sounded great that way, when I was playing as the only guitarist could make it sound like there were a couple gutiars playing, The Whammy pedal with its detune gives that effect as well, pretty cool.

    not sure that a TC Nova is going to work in a parallel FX loop, have not played one, but its a left and right, and I don't see a mix on the pedal.
