How do I use TheGigRig with the effects loop in my amp?
If your amp has an effects loop it can be great to use effects like chorus and delay in the loop of the amp while your OD effects go direct to the input in the front of your amp. So how can I set this up with TheGigRig? Have a look at the signal path diagram below, and then I'll guide you through it. |

| | | I've done this diagram using TheGigRig Pro-14, but of course you can do exactly the same thing with the MIDI-8. You can use any of TheGigRigs effects loops, I've just used no.7 for this exercise.
Following the signal path diagram above, you can see that the guitar signal enters TheGigRig Pro-14 on the right, then progresses through the first 6 programmable true bypass effects loops as normal. From there it travels from the send of loop 7 into the input of TheGigRig HumDinger, out of the Isolated out of the HumDinger and into the input of the amp.
Why have I used a HumDinger?
Many amps are very sensitive to earth/ground loops, and you can get a ground loop when you join the earth/ground of the pre-amp and power-amp sections in the same amplifier. The HumDinger isolates the earth from the input and the FX loop section of the amp ensuring quiet operation. Some amps don't need it, like my Two-Rock for example, but many do.
(If you buy a HumDinger for this purpose and realise you don't need it, there are loads of other geat things you can do with a HumDinger and TheGigRig, but of course you can always just send it back for a full refund.)
OK, so, all the FX placed in loops 1~6 will be routed to the input of the amplifier. Now the signal in the amplifier goes through the pre-amp section and out of the 'FX Send'. That signal is now sent back to TheGigRig Loop 7 return. Your pre-amp tone is now in TheGigRig. Selecting any preset that includes any effects loop after loop 7 (8,9 & 10) will send the pre-amp through those effects, then finally out of Output 1 the amps 'FX Return', which send the signal to the amps power amp.
All the pre-sets MUST include loop 7 (or what ever loop you have used to engage the FX Loop) otherwise the signal will pass directly to the power amp.
