As an external mixer I will have a soundcraft EFX8 and a Mackie 1202 (sub mixer). Also a Delay, a stereo filter and one outboard compressor.
+1 on Soundcraft, -1 on the EFX series.
Save yourself some money and get the EPM6. Same mixer, no internal FX. Then hop over to Reverb and/or eBay and grab some rack hardware...since the EPM6 has a typical small-mixer mono-send/stereo-return setup, devices such as the venerable Yamaha SPX90 will work very nicely in that situation, and give you a lot more FX capability than a little onboard FX chip.
I’m hearing your advice on Maths as a lot of people tell it’s one of the best! Do you think it can adapt well in this setup ?
I don't even have to look, since Maths is perhaps one of the finest modulation sources devised. It works in ANY setup, as long as you've got space for its 20 hp.
Even people who grumble about Maths eventually wind up with one. No lie.
