I had at one time owned an H9 Max.  One preset that I thought was brillient was called (I think) Les to Leo or Leo to Les.  It did a remarkable good job of making a Les Paul sound like a Strat.  I am thinking of rebuying an H9 but most likely a Core model.  Will I be able to find and upload this preset?

As a broader question, I will be using this for live performance and don't need 99 presets.  I will use only 5-7 that I can scroll through on stage.  Probabally a Flanger, Phaser, tremolo, a delay, etc.  Will the core unit be the best was to go for this usage?

The Les to Leo preset is from EQCompresser algorithm. H9 Core only has one algorithm H910/H949, which cannot do flanger, phaser, tremolo effects. You may purchase algorithms for $20/each if you get a Core. I think an H9 standard or Max may be better for your usage. 

If you already have a Max or Standard, you can get a Core and share all the algorithms on the Max or Standard with the Core.
