HD Pro dual amp patch...stomping an amp on/off?
by jjulien on 2012-12-18 07:30:12

Hey all Just got an HD Pro yesterday...learning in process....does anyone know if with the shortboard MK II can you assign a button to stomp an amp on and off withion one patch that has two amp models running? For instance...Seven Mary Three- Cumbersome..starts with a real high and presence amp and then a deeper throatier amp kicks in an they play together...could i make a patch that does this without having to make two patches...?

Thanks!

Sure you can - just assign the Amp to any footswitch, like you would an FX model. The associated footswitch on the MkII will toggle the amp on/off.

If you assign the footswitch to one of the two amps, when you switch off one of them you would still hear the guitar signal (without amp) from that path mixed with the amp active in the other path .. not an ideal solution I would say ..
to obtain a perfect instant mute would be much better to put a volume pedal fx set to 0% after the amp (that you want turn off and on) in its path and assign the footswitch to it ..
when you'll press the footswitch it will remain audible only the other amp

There's a couple of ways to go about this, and making it work perfectly is a little more in depth than "turning an amp on and off." 

For starters, assign both amps to the same footswitch, then set the default of the patch to have one amp on and one amp off.  Pressing the footswitch will toggle both at the same time - turning one on while simultaneously turning the other off.

Then there's the issue of the raw guitar signal still being sent through the off amp.  You have a few options:

one, as hurgnanico suggested, put a volume pedal set to 0 immediatly after each amp, and set them to the same footswitch as the amps, also one turned on and one turned off. 

Alternatively, scratch all the footswitches discussed here, and set the volume on the pedals to be controlled by an expression pedal.  Set one volume pedal so that Max=100% and Min=0%, and the other that Max=0% and Min=100%.  The pedal will then crossfade between the two amps.  In this setup, both amps should turned on. 

My two cents worth, you're trying to reinvent the wheel.  Dual tone patches eat up alot of DSP, and if you're only going to run one amp at a time, you are better served with seperate patches.  Still, if this is what works for you live, I hope the above advice helps.  Happy tone hunting.

I want to be able to start with one and then kick the other one on so their both on....sounds a little tricky..but still a capability I have not had in the past...here's a follow up question to this....I have a Pod XT Pro with the FBV shortboard as well... (just got the HD) the book says the FBV shortboard is compatable but the the MK II is perferable. I planned on getting the MK II but do any of you guys know what are the capability differences between the too for the HD Pro's case?

Ah, actually that's way easier.  Yea, like hurghanico said, set the amp to a switch, set the default amp to off, and set a volume pedal set to 0% after the amp.  Then set that volume pedal to the same switch as the amp and default the volume pedal to on.  Then stepping on that switch will turn the amp on and deactivate the pedal (letting the signal through). 

You'll probably want to "mono-ize" this signal, so both the left and right outputs get both amps - set both left and right on the mixer block to center, or use a mono effect after the amps. 

I know nothing about the FBV vs the mk ii.

Not sure about the HD Pro, but with the HD500 there's an easier way to completely mute the non-active amp path. Just go to the first page of the Amp Edit Display, there you will see a single volume knob for the "off"-amp model. This is the Amp Model's Bypass Volume, turn this to 0 and that path will be quiet. Using the arrow keys, choose the second amp and turn that bypass volume to 0 also.

Simple, and you save two effect slots in your patch compared to the volume pedals solution. (See section 6-7 in the Advanced Guide, http://line6.com/support/manuals/podhd500)

bravo!..

surely that's the best and perfect solution..

I had forgotten the existence of the bypass volume (I never use it)
