Tips & Techniques:A Pet Trick for the 2500 Fans out there

Someone was asking me about the l/r link on the 2500 in another thread, and my ramblings reminded me of a trick I use all the time and figured I'd share here, I imagine some guys will find this as cool as I do.

The 2500 has one set of controls, but there's a very cool way to use the two channels serially and have separate control over the amount of GR you get on each channel.

This is how you set it up:

1) Patch channel 1 into channel 2

2) Set L/R to Independent

3) Engage Feed Back mode

4) Engage Manual Output Gain, set to 0

5) Set your meters to view Gain Reduction

The combination of #2 & #3, coupled with the way #4 feeds the energy back into the detector, is the secret spice here.

Try this:

1) Send a mono drum buss, a good balance of kick snare and room, into channel 1. Out of 1 into 2.

2) Set your ratio low, start with 2:1. Set your attack to 10ms and your release wherever you like it. Maybe 50, maybe 400, maybe 1.5, depends on the thickness/distortion factor you want (or don't).

3) Use the threshold to get some squeeze on channel 1. Note how at some point channel 2 starts reacting too, but probably less.

4) Goose the output gain knob; what should happen is the GR in channel 2 will increase at a greater rate than channel 1.

This is where the fun begins. Essentially the Threshold is threshold control for channel 1, and Gain is the threshold control for #2 (that's not actually what's going on, but the effect is roughly the same).

So grab both the threshold and gain knobs, and move them around simultaneously, one up the other down, or both up, or both down. Listen to the ways that the transient gets shaped differently by having the different channels do their thing in greater and lesser proportions.

The amount of control you have over the sound here is phenomenal. Don't forget to play with attack and ratio's.

Very cool! This is thinking outside of the box. Or more in the box in this case!

I do something similar with the 2500 at times. A double dose can really amp (or rather... comp) things up.

Secret spice is an apt description!!

Hey Greg,

How would you do something like this in Logic?

I set up a drum loop in ch. 1, out to aux 1, set up a mono 2500 in each, but can't really seem to hear what I'm supposed to (?)
