Trouble with level/gain Loop ACTIVE or NOT - 3ch Dual Recto

[3124+]

I don't recommend the series mod. The parallel loops are best and work perfectly if you follow these steps:

1. Set loop to always on.
2. Set fx processor to 100% wet.
3. Use amp's MIX knob to control wet/dry blend.
4. Leave your FX processor active at all times, then use a volume pedal or mute box to control the fx like this:

Amp send > Volume pedal > FX processor > Amp return.

Heel down will give you 100% dry. Toe down will add the fx. Give this setup a try. I'm sure you'll be pleased with the results.

Hey 3124+,

Thank's for your complete answers, so cool man, I learn a lot about my amp thanks to you.

What if ... I use the SOLO function to balance my output level when LOOP is disable ?! I've followed the schematic and I've well understood the issue with J175R and the Mix pot grounding. I put below the scheme of my config. I think I will use the "AMP CONTROL" output of my GT-8 (Which is controlling the Voodoo lab by MIDI and then CH1, CH2, CH3 and LOOP of my Recto), So, I can configure it to activate the SOLO mod when LOOP is OFF/Disable...? Because I really need my 2 loops, one for my TS-9 and one for my Modulation and Delay Line6 Stomps. So by this way, my SOLO pot will act as the Volume pedal you advised me to add.

Thank's !

I have to respectfully disagree with 3124+ about parallel being better, because it has drawbacks, especially on a Recto. The parallel loop sits between 90% and 10% wet at all times. This isn't ideal. Unless the effect(s) unit has a kill dry feature, there are going to be phase issues and it will sound like a stationary comb filter (flange) on the combined signal. It is most apparent when the mix settings are somewhere other than fully clockwise or fully counter-clockwise, which is where you'd be aiming with a 100% wet signal from the effects.

Parallel also makes any filtering or EQ effects useless, unless the loop is set to 100% which this loop cannot do.

Series also has its strengths and weaknesses. If a poor quality effect is used, the whole signal suffers from it. That might have been a concern 20 years ago, but not so much these days. The benefit is there is no messing about with controls to determine the effect mix on the fly and the comb filtering is gone. Just set the wet/dry on the unit when creating the patch and carry on.

I guess it depends on what you need. Both types have their advantages. I did a different series mod and I'm happy with the change. I want a balance between precision, control, and ease of use with my effects. Also, that comb filtering drove me nuts and the basic tone of the amp improved with effects in the loop, but not activated.

I prefer parallel because the dry signal does not pass through any cables or fx processor circuitry. It works like a send on a mixing console. You get full reverb and delay trails, seamless integration, no level issues, best signal integrity. It is also more reliable.

You can create EQ and filtering effects using short delay times. Modulated delays generate chorus and flanging. The Recto loop was never designed for stompboxes. A Lexicon or Eventide fx processor in a parallel loop is bliss.
