Carl Martin Combinator

[tomgreaves]

I am currently using all eight loops on my combinator and would like to add a noise reduction pedal in between the 5th and 6th loops to be on constantly, regardless of what loops are selected.

Would it be possible to wire up the remote outputs/inputs to cater for a loop to be constantly on between those two loops? If so any tips or help on how to do so would be great.

Open it up. If it's all layed out on PCB (likey) it'll be hard. You'll have to find a via where you can add an insert and you'll have to cut some traces on the PCB to break the existing signal paths.

If it's not PCB-based it wouldn't be that hard to put an insert in between any loops. You'll have to deal with drilling the enclosure to add a jack. I suggest adding it as a single TRS jack, not two TS jacks. True insert-style. You can use a switched TRS jack so that when you don't have something using the insert (i.e. no plug in the jack) it shunts the insert and your unit works like it was stock.

Even if it is PCB though do you still think it'll be possible or will it be a bit of a gamble? I've already got some jacks at the top of the combinator that I don't use for some 'remote' which Carl Martin never advertise what it actually does, so I'll probably use those if possible. I don't know if this are a just TS or are TRS, how can you tell?

I'm really new to all this so I don't really know what's possible and what isn't.

Even if it's PCB-based it's possible. But if you're green like you say you are I wouldn't recommend you make your first foray into modding an expensive pedal be cutting PCB traces.

I also wouldn't try to reuse anything on the unit. I'd drill and install a new TRS jack.

Open it up. Take some gut shot pictures. Post them. I can get more specific if you want.

The remote jacks send a signal to an external device like your amps channel switcher. Say you have a compressor in loop 2 and you only use that compressor for your clean tone. When you select a patch that has loop 2 active, the signal is sent to your amp to change channels and then change back once to the loop is deactivated. At least that is the way I understand it.
