Proto YOU ARE THE MAN! THANKS!
I have another amp in the Rg-16 as well, and now my little brain can't figure out where to put it, I basically had the the beginning of the signal the same (output to loop 5, I AM using an RG-16 by the way) with the VHT UL, and then on to loop 6, but I cant figure out how to put the UL in there now :/....Any ideas?
Basically, want the UL on its own, and then the herbert/ ENGL rig to switch between, but to be able to run both the UL and diezel or UL and diezel poweramp/engl preamp together in stereo.
No problem, glad to help!
In order to add in the UL and not sacrifice another loop, you can try combining the input signals to the Herbert, ENGL preamp, and UL with Y cables. I would definitely use a buffered output if you do this as there is potential for tone suckage of your guitar input.
RG Output --> Split with Y cables to --> RG In 5, Herbert In, ENGL In
RG Out 5 --> Not Connected
RG Send 5 --> UL In
That will enable you to switch the UL in for a blended tone, but it won't allow you to use the UL by itself. If you want to be able to do that you'll need to sacrifice one more loop... Now, engage Loop 5 to give the UL a signal, turn it off to only have the Herbert/ENGL.
If you want the ability to run the UL by itself without the Herbert/ENGL do this: (whole diagram again)
Guitar --> Input
RG Send 1-4 and Return 1-4 are for your preamp effects.
RG Output --> Buffer In
Buffer Out --> Split with Y cable to --> RG In 5, RG In 6
RG Out 5 --> Not Connected
RG Send 5 --> UL In
RG Out 6 --> Not Connected
RG Send 6 --> Split with Y cable to --> Herbert Input, ENGL Input
Herbert Loop Send --> RG In 7
ENGL Out --> RG Return 7
RG Out 7 --> RG In 8
RG Send 8 and Return 8 are for your one loop effect
RG Out 8 --> Herbert Loop Return
To enable the UL: Loop 5 ON
To enable the Herbert/ENGL: Loop 6 ON
To select the Herber: Loop 7 OFF
To select the ENGL: Loop 7 ON
Loops 1-4 are for your preamp effects, Loop 8 is for your loop effects. Loop effects will only work for Herbert/ENGL.
Loop 5 allows guitar signal to pass through to your UL. Loop 6 allows guitar signal to pass through to your Herbert and ENGL. Loop 7 selects between the Herbert and ENGL output fed into the post effects and Herbert power section.
NOTE: This scenario does not account for:
1. Potential ground loops between amplifiers. You may need to add transformer isolation to the input of one, two, or all amps. This is due to potential ground loops forming between amplifier inputs, effects loop send/returns, etc. You may be able to lift a ground or two on the amp side of audio inputs as a cheaper alternative.
Do not ever lift grounds through the amp power cables!
2. Phasing issues. I imagine since you have already run the Herbert and UL in stereo this wasn't a problem. You may however have unexpected phase issues once you bring the ENGL into the mix. It may have a phase output switch, and/or a balanced output. If it does, then you can easily adjust it to be in-phase with everything else. If not, you will need a transformer isolation box with a 180 degree phase switch to bring it into phase with your other gear. Oh the joys of stereo!
3. With both the ENGL and Herbert receiving an input signal whenever Loop 6 is engaged, this could present a problem where the returns are blended in Loop 7. Both signals have the potential to be very hot and you may get some bleed from one or the other, or both. The easiest way to counteract this will be to make sure to run both preamps at a lower level and compensate with the Herbert post loop master volume. Otherwise, you will need an additional loop to turn the signal off to the ENGL when not in use, just as in my first example.
