Signal Level Question with HD400 + Boss AC3 Stompbox

I have a unique setup I need to pull off. I'll try to keep it simple.

 

I play Electric Cello. I use a Boss AC3 Acoustic Modeling stomp pedal. It has 2 ouputs. A or B (not A+B)

 

Output A (effect off) is instrument level, and goes to my POD HD400.

 

Output B (effect on) is Line level, and goes straight to my mixing board/PA.

 

What I want to do, is get another HD400 or an M13 and send Output B to it. But I'm concerned about plugging a Line Level output into an input designed for Instrument Level.

 

Can the HD400 or M13 accept a Line Level signal without any problems?

 

Or is there an adapter unit or something that can change Line Level into Instrument Level?

 

Hope I described that well enough.

 

Thanks

    There are certainly devices that adapt Instrument level to line level and and reverse.  Off the top of my head ....

     

    Ebtech Line Level Shifter --> http://www.ebtechaudio.com/llsdes.html

     

    GLab SA-1  --> http://www.glab.com.pl/sa-1_en

     

    The alternative is to plug the Line out on the AC3 into the FX Loop Return on the HD400.  This can run at line level if required.   I think you may lose your first effects block but the rest should be ok.  You would need to configure the FX Loop within your preset.

     

    Depending on what you want:  you could even look at using the FX Loop Send to go out to the amp (set at instrument level) and the main POD output to go to the PA (at line level).  You would need to mess with the FX Loop Mix control to ensure that you still got signal at the output but you would get most of your effects and use just the one output on the AC3

      To clarify more, my goal is to plug first into the AC3, since it also acts as an A or B switch.  From the AC3's 2 outputs, I want 2 separate effects processors.

       

      When the AC3 is off, it sends a dry signal (output A), which I would like to process with effects tailored towards heavy distortion style of music.

       

      When the AC3 is on, it sends an acoustic modeled signal (output B), which I would like to process with effects tailored for that 'real cello' sound.

       

      This way I can switch back and forth between 'clean authentic cello'  and 'heavy metal cello' with 1 stompbox. Each with its own separate  effects processing. (2 HD400's)

       

      This also enables me to have 2 separate channels on my mixer, since I use the HD400, I don't use an amplifier. I just record directly, or play through the mixer/PA system.

       

       

      A little digging yielded me the "REAMP JCR" by Radial Engineering. This looks like it does precisely what I need, but also costs $200.

      If thats my only option, so be it. I was hoping for a cheaper alternative.

    I think some lateral thinking might solve your problem easier.  If you're going to be stomping on something - and using only one sound at a time....why not stomp on the HD400???  The 400 has an effects loop. 

     

    Cello -> Pod -> FX send -> AC3 -> FX return -> Pod -> PA/recording device.

     

    Then set your patches up accordingly.  In the metalz! patches, don't use the FX Loop block, in the acoustic patches, use the FX Loop block in the first slot.  Then you can change patches to change sounds, and no more mucking about with line levels.
