I'm glad you have discovered TE. I had an AH200 for years. Definitely agree with not using the mid pre shape, especially live. I boosted the low mids and had a great live sound and with my Ray cut through the mix. I use a TC 450 head and Barefaced Retro 210. Do I miss my TE head? Yeah I do at times but I'm happy with my current rig and glad I ran some TE equipment in my past.
I'd be interested to hear what you make of it in gig situation.
