Post Amp Effects

[m.z.]

I want to try and run my delays/verb etc. post speaker what is the best way to do this? Have any of you tried it?

[TweedBassman]

hm... you mean, effects after the signal is amplified and sent to the speaker?

the only way i can think of is in a live or recording situation, where a mic'ed signal has reverb or delay added. in that case, you'll need a mixer with an aux send, a good sound guy, good PA, some nice rack effects...

amp -> Hot plate set to load -> effects -> clean FRFR amp -> cab.

I haven't tried this, but I've read about others getting good results. I've done the amp -> hot plate set to load -> other guitar amp -> cab and it works amazingly well.

Chris in Grizzly bear does this with his vocals and a clarinet, I'm sure you could do it with a guitar cab. Get a mic and a small mixer, 2 channels should suffice, then run the out through your effects and from there to the board.

If you're just doing this at home, it's not really cost effective as you would need a PA to hear what you're doing, but it's easily doable live.

sorry... I'm lame. What's FRFR stand for? :o

If you are a stickler for a real speaker tone at perfromance volumes, you have to mic.

If you accept speaker simulators/load simulators, you can use a hot plate or similar device or use a modeler (Line 6, Tech 21, etc.) and place the delays verb after the modeler and then into a PA or other clean amp system (I do this with a Tech 21 TriAC)

I tried most of the above:

Amp -> THD Hotplate (Line Out) -> HOG -> Delay -> Recording Device

Sennheiser Mic -> Recording Device

Recording Device = MOTU 828MkII 8 in, 8 out audio interface/line mixer

Recording Device had a line out to my Roland keyboard amp. Got unwanted distortion unless I turned the Line Out level really, really low. Never did figure out what I was doing wrong.

Ended up using a VoodooLabs Amp Selector to split the signal - one to the amp, the other to effects, running the effects directly to MOTU, so I had separate tracks for dry guitar and effected guitar. I had the mic carrying dry amp signal to one of the MOTU's Mic inputs. Was happier with this result.

Thanx for all the ideas guys!

As stated above, you need to either mic your speaker and run that to effects, or involve a speaker simulator into effects.

Are you wanting to record directly, play live, or just hear the post speaker effects for home use? That will impact what you end up doing.

For years I have successfully used my THD Hotplate as a load box hooked to the amp's speaker out, and then run it's two line outs to an ADA cab simulator (Microcab II?), and out from the ADA to effects. From there you can go into a power amp or recorder, etc. I think David Torn uses or has used this system. The ADA is no longer made, but Palmer makes boxes for that purpose (some may include a dummy load and speaker emulation, if I remember correctly).

I'm mainly interested in live application... I've wanted to do this for a while. I can't always count on there being a decent p.a. though... so I don't know how practical this would be... but I want to try it anyway! I read about Bernard Butler (Suede) doing this. I think I read that he went stereo... but with one amp (micing front and back of the combo) then to fx and small board...
