I'll agree with fyziqs about Eden gear having a strong mid presence, but the flexibility of the EQ on those amps is vast. There's nothing about them I've ever found hard to tame.
You already know you like the Eden tone, but bear in mind the WT-550 is still a 10-pound amp, which is not so light by today's standards.
If you didn't already own Eden gear, I'd steer you that way, but since yopu already have some in your stable, I suggest you try something new. Go for the Epi, and you can always drag out the Eden if you're jonesing for that sound.
