I am in process setting up the Helix Line 6 with 2 additional expression pedals, Earnie Ball volume pedal, JVM410HJS (master), second JVM410H, ProCo RAT, Ibanez FL301.
I am making the following connections:
- FX Loop 1 connect to PROCO RAT
- FX Loop 2 send to JVM410HJS input, and return to the 410 FX send
- FX Loop 3 connect to Volume pedal
- FX Loop 4 connect to FL301
- Output Left to JVM410HJS FX return
- Output Right to JVM410H FX return
- Midi out to JVM410HJS Midi in; JVM410HJS Midi Thru to JVM410H Midi In
- EXP 2 and 3 connected with line 6 expression pedals
Issue: master volume on both Marshall amps set to 5, both amps drive a 1960AV cab, the volume from the second JVM is remarkably lower. I checked, use same programmable JVM FX loop and set to full wet signal.
I am running now the Output right to JVM410H input and use channel 1 in clean mode. This helps to put both amps at same performance level. Don't need to run Midi to second amp.
Does anybody have an explanation for this?
I have bypassed all effects, and only have FX Loops 2 and 3 active.
Additional info: use the following effects (all mono) before the JVM410HJS - Wah, Distortion, FX Loop 1, EQ, Phaser; after preamp - EQ, compressor, FX Loop 3 and 4, Chorus, Delay, Reverb, Looper; programmed clean, crunch, OD1 and OD2 for each of my guitars (Les Paul Cst, ES335, Strat 1, Strat 2, Driskill Diablo); can now operate at Bank and Preset levels and still use the JVM foot switch as well.
Use internal expression for Wah, external expression for various effects parameters - reverb depth, etc., all cables are high quality planet waves; effects sounds are excellent; still need to tweak Marshall and EQ settings for each guitar
