I have been linking channels in my Trinity 18watt. It sounds very nice as the difference in the two channels creates a thick THICK sound. I don't know why it didn't work before but it is now.

What I have done is plug into the top input to the normal channel and put a short cable between the bottom input of the normal channel to the TMB channel. I set one channel for brighter sound and the other for a bassier darker sound. I then mix to taste.

While I am on the subject, sometimes I set the TMB channel with the master up full and the volume on 3 or 4. This gives a rounder less edgy tone that reminds me of a cranked Super Lead. It is quite different than the preamp cranked and the master on 3 or 4.

Yes, we have done this as well. Very full, complex, meaty sound. Great tone. Great ranger of tone control as well. I would highly recommend eveyone try it out at least once!

I thought there was an issue with doing that on the TMB as a result of the phase inverter setup or something. Wait I found a post from Zaphod_Phil. I guess it's just the opposite.

"You can't jumper the two channels of a regular (trem) 18W, as they are oppositely phased to each other. A TMB's Normal and TMB channels are in-phase with each other and will therefore mix nicely. This is another great feature of this amp design.

I guess that makes sense since the normal channel signal goes through one triode preamp and the TMB goes through 3 triode sets. Normal is "flip" and TMB is "flip flop flip" so they both end up as "flip" ?

I'll have to try that ! Does it matter which input you use as the guitar input and which one jumps the signal to the TMB channel? You have two choices, right?

Don't think it matters. See lbets post above

I tried this as well with great success. As a usual TMB channel user, it was nice mixing in the Normal channel. Anyone try using an ABY box instead of jumping? That might be a nice way to really get a variety of sounds, especially in a live setting.

Good Idea. You can have differnt fx down each branch of the Y too.

Yep. It has to do with phase. A stock 18 trem will not allow you to jumper the channels as they phase relationship is even so you will end up with a thin sound as the 2 channels cancel each other out. A TMB has an odd relationship, so it's all good. Jumper away and enjoy the tonal buffet!

I should mention a trick I picked up from EJ. He doesn't jumper the channels, but uses a Monster Y cable (audio section of your fav A/V store) to split his signal into the high input of both channels instead of jumpering them with a short cable the old fashioned way. That gives you even more effect.

I've just discovered this thread.
I must try this as well. I thought that I couldn't jumper with the 18 TMB Trinity but like the post above states, that must have been the classic 18 watt with tremolo (not the TMB)

Does the sIII have the ability to jumper channels as well?

Yes. the 'Classic' sIII has 4 inputs, but no reason you cant do it with the 'Classi' 3 input version of TMB. The Trinity TMB has had 4 inputs for a long time as well now.
