I've tried it basically everywhere except for in front of my wah and distortion, and it sounds good pretty much anywhere I put it. But I always end up putting it at the end of the chain, goin' into the front.
I'll give you guys my rig: various
Ibanez guitars into Input of Boss NS-2 (then the following effects going through the Send/Return of the NS-2)- Bad Horsie II (first in effects chain) Boss MT-2(Distortion), Boss GE-7 (EQ), Boss CE-5 (Chorus), Boss DD-3 (Delay), Boss RV-5 (Reverb) and then the Sonic Stomp. All this into the front end of a Legacy 212 Combo. THIS IS THE ARRANGEMENT I HAVE AS OF YESTERDAY. This set-up fixed the problems I was having with my delay through the fx loop, which was a staticy, distorted quality to the repeated notes, getting worse with each repeat (this was only with distortion ON). With that set-up, I had the chorus, delay and reverb going through the fx loop of the Legacy. Take them out of the fx loop and their fine. Thought my delay was shot there for a while.
I just found out that the fx loop on the Legacy is a serial loop, not a parallel. Delay is suppossed to go through the fx loop. The Chrous and Reverb sounded fine through it, just not the Delay. That's what made me think it was shot. But then I read this on Gear Monkey:
Just my .02 cents and nothing more...
Effects loops became a demand item by crazy producers like Phil Specter. By 'crazy', I mean crazy in the studio, although with Phil, the term's appropriate no matter where he happens to be. Anyway, Phil and those like him went for bigger and more outrageous production in the studio and it's never been the same since. Before the Beatles' 'Wall of Sound', producers were just concerned with accurately capturing what the band sounded like. Phil's idea was to be a creative genious and paint with sound. The noise the band brought with them was just the starting point.
Eventually, the sounds and tones that got recorded were way different than what the band could produce on it's own on a live stage and the Uh-Oh factor came into play. So, in an attempt to apply effects in a more consistent manner and in a way that at least came close to what was recorded in the studio, the effects loop was born. Yeah, they existed in high end audio gear long before they appeared in geetar amps, but it was still a new thing for axe-wielders.
Useless information, but now you know.
Here's the way I use them:
I try to keep manual filter effects (wah, Leslie sims, etc), volume, and drive effects (overdrive, fuzz, distortion, etc) between the guitar and amp. I'm either trying to push the front end of the amp or I want the amp's overdrive to go to work on the effect's signal. I leave the effects loop for modulation effects (phasers, flangers, auto-filters, etc), noise gates, reverb, EQ, and stuff like that. Generally, I want those effects to impact the whole preamp signal and I want the power amp to magnify whatever comes out. There are no hard and fast rules, so switch and swap as you like.
Another question about loops is which is better - serial or parallel? A lot of pro players like parallel loops, which mixes the dry signal (no effects) with the wet signal (effects). The effect has a more subtle 'effect' on the amp's tone that way, but some feel it's more powerful. One aspect of parallel loops I like is that if you use digital effects (yuck!), some of them have a bit of a delay because the sound drops out when you switch patches. A parallel loop makes sure you always have sound coming from the speakers.
Personally, I like the series loop, which is all wet all the time. That doesn't have to mean gobs of reverb or chorus or whatever. That's why those little boxes come with knobs and stuff - set it how you want it. It also makes sure your noise gate for a
high gain amp actually does something... and with most high gain amps, it NEEDS to do something. Just because the computer cleverly disguised to look like a guitar amp is dead quiet when you're not banging away at it's digital sim chip, doesn't mean a real tube amp should be as polite. This is rock-n-roll, after all.
The last consideration is signal level. Your average guitar hanging on the wall at Banjo Center puts out around -20dB, your average stomp box around -20 to -10dB, line out level is 0dB, and your favorite rack gear operates at +4dB. Boosting a signal 3dB is a doubling of power, so you can see that there's a huge difference between -20dB and +4dB. The best loops (like the Swamp Thang) have a level switch and/or level knobs to allow you to use whatever you brung. What about those loops that don't? Check your documentation and you'll see that they're most often rack level (+4dB). What's that do to your little green stompbox? Nothing, except distort the heck out of it - and not in a good way. Keep that in mind the next time you plug in a box to your Marshall loop and are tempted to say, "Dang, this pedal sucks!"... It might not be the pedal.
Just fishing for suggestions you know. BTW, my rig sounds pretty bad ass as it sits now, BUT IT CAN BE BETTER DAMN IT!!!!!
